    Summary: A static deflection test was previously performed on several carbon tubes allowing them to be compared based solely on “stiffness”, or the “spring constant” for each tube. A link to the discussion can be found here: http://kitelife.com/forum/topic/7329-carbon-tubing-comparison/ Experienced Rev fliers have responded with comments regarding the “reflex”, or response of the carbon tube frame being more important than the “stiffness” or weight of the frame. Experienced fliers select a preferred frame based on wind conditions and the selection of sail type (vent options: none, mid, full). Additionally, modifications may have been made to the “stock” sail design to improve performance of the kite. The data presented here represents the dynamic properties of a carbon tube independent of a sail. The Data: Let's get right to the data! Here is a link to the current Excel spreadsheet with both static and dynamic test results for the rods that I have tested. A copy of the table is included in this post but does not let you sort by manufacturer or characteristic. http://www.donkush.com/CarbonTubeProperties.xls here is a copy sorted by 1st Amplitude 5” Perturbation: Here is a copy of the worksheet "Deflection and Reflex comp" which compares dynamic measurements with the commonly used Rev 3-wrap rod with silver label: A positive % means that the test value for that tube was greater than the Rev 3-wrap test value. Likewise, a negative % means the test value was less than the Rev 3-wrap test value. Discussion: Specifications for carbon tubing that you purchase for the purpose of constructing or modifying a frame combination yourself only include tube ID and OD dimensions, and an overall weight. Some tubes and frame sets will only provide a model ID and no other information. The more experienced kite flier or builder will be interested in more information than this. Hopefully the tests that I have conducted will be useful to you although you will see from the pictures that I don’t have a NIST certified lab. I was able to conduct these tests with readily available household items (for me these were readily available ) and a little ingenuity. Description of the Carbon Tubing Response Test: A 31” tube was secured at one end of a test table by a ferrule allowing a full 31” section of tubing to be deflected and oscillate. The 31” length was deflected by 5”, released, and allowed to oscillate until it settled. The amplitude of the first vibration response was measured in inches. The frequency of vibration was measured in HZ (cycles per second), and the settling time was measured in seconds. (settling time is defined as the time it took for the tube to stop vibrating after the initial disturbance). Test Table Picture: The measurements were taken using audio technology. A small wire (whisker) was fastened to the end of each tube that was tested and a small microphone was placed exactly in-line with the stationary tube. As the tube oscillated past the microphone it recorded the impact of the whisker. Since the audio was sampled at 44.1 KHz the data is quite precise. Frequencies and settling times were analyzed using audio editing software. Data Sheet Picture: A data sheet was used for each rod tested. The data was recorded and then entered into the excel spreadsheet that has been posted. Sonic Performance Pictures: Multiple tests were performed on each rod and the results were averaged. Here is an example of a rev 3-wrap rod showing 3 response tests: Here is a picture of one test with markers drawn at each impact of the microphone. Two impacts define the Period in seconds. 1/Period defines frequency in Cycles per Second known as Hz (see highlighted and circled value in the picture). In the case of a 3 wrap rev rod the Period is .062 seconds on average and the frequency is (1/.062) or 16.129 Hz: The first amplitude deflection however was measured manually. A toothpick was held perpendicular to the testing table and at the end of the tube. The toothpick was adjusted until the tube barely touched it during the first amplitude deflection. I don’t have a picture demonstrating this test but here is a picture of a sample test sheet showing where the first reflex of an example test sheet for the 3-wrap rev rod where the first amplitude was marked. It is at the end of the perpendicular line drawn from the Centerline (CL): What does this all mean? Hopefully this information is useful to you and can inspire further discussions regarding frame preferences and sail choice in the forum. I will offer my initial interpretations of the data with hesitation because I know that many of you will have your own observations... Again, Wind Speed, Sail Choice, and Sail Modifications are all factors in the kite’s response and performance. Frequency test: The frequency test results are very similar between each rod with the exception of the SS P400 and the Rev 3-wrap Green-stripe. Almost all the rods oscillate at a slightly lower frequency than the Rev 3-wrap. The frequency value could indicate how quickly the rod, when used in a sail, will try to return to a static position after a disturbance. Perhaps a point for discussion… 1st Amplitude Response from 5”: This test possibly indicates how “springy” a tube is. A large 1st amplitude would indicate that the rod wants to flex easily. Perhaps this would give you a very “bouncy” experience when used in a sail. Silver Race rod test results would indicate that they would seem considerably less bouncy than the 3-wrap. The SS P-90 is the bounciest of all which I would agree from my experience. Settling Time: This test would also seem to indicate how quickly a rod will return to a static condition after a disturbance. It adds another dimension to the frequency characteristic that describes how quickly the amplitudes during oscillation diminish to zero. Race Rods and SS PX tubes have a shorter Settling Time than the 3-wrap standard; this has me curious now and perhaps my first question back in the forum: For those of you with SS P-3X frames, how do you compare this frame to the Rev 3-wrap? The SS P400 seems like it wants to vibrate forever! Well, I will end this blog now and look forward to continued discussions in the forum. S.F.

    Boxing Day 2015. I was going through the recyclable bin in search of some instructions that were reported missing from my littlest girl's "Frozen" Lego set. I kid you not! I noticed a guy with his two kids and a kite at the park. I paused to watch, like any kiter would do. I watched them struggle to get it into the air. I saw the kids lose interest. I had a déjà vu from exactly 4 years back. Quickly told my wife I was just going to help them out and over I went. Went and introduced myself and offered some assistance which he readily accepted. I gave the kite a once over. It was a cheapo dualile, would've cost $20 at most. Plastic sail, cheap lines. First I gave him a basic run through, let out all the lines when it's down on the ground not in the air. Give to the kite if you heading South to the ground. Small hand movements not massive arm yanks. After a couple of minutes of successful flying, there was a gust that just stretched out the sail in a very unkind way. I quickly ran ran back to my house and grabbed my SKD Seven Std and 80 foot lines. Quickly set up, explaining what AND why I was doing. A quick flight to make sure the bridle was dialled in. Then handed over the straps. All the frustration just melted away from his face. Sure we didn't do any tricking, just flew around. But! He was flying and not struggling. His kids called out to him that it was time to go so he handed me the straps back and I flew a few figures, stalls and slides for a bit of fun. We talked while I packed up. All about kites. I think I opened his eyes to a lot more than a $20 dollar kite. Then, and there is always a then, he asked me how much my Seven was. The smile didn't disappear totally from his face when I told him... I explained that it was an investment over a few years. Break the cost of kites down over a few years and most people see the value. I pointed him towards Kitelife.com as a portal into kiting. Gave him a website for a kite shop here in Oz. Gave him my details. Hopefully there was enough of a spark to keep going. Only time will tell.

    Sometimes we leave on a vacation having no idea where we'll wind up or how long we'll be gone. It is a powerful kind of freedom that our vast country provides. So we decide one evening to load a little gear into the RoadTrek the next morning & head up to a small town on the Ohio called Madison. We chose to leave with minimal preparation planning to buy anything we might have forgotten along the way. After a couple evenings on the road we decide we will venture onward. There was something in a store that we wanted. Wall Drug is in western South Dakota. I like to drive. When I left home that first morning I actually thought about not taking any kites. Maybe try to buy a few along the way was my logic. But at the last moment I just had to grab a few. I chose from some laying on the kite table. Tornados were threatening in the mid west so we were watching the storm patterns in order to avoid severe weather. We have had some crazy times on previous trips. We stopped for the night in western Illinois. Stayed in a campground that was surrounded by fields of ankle high corn. The wind was blowing from the west at a good pace with some gusting. Time for high wind kites. Pulled out the Micron, attached it's tail & entertained the neighbors with the humming & buzzing little gem. The wind picked up a bit. Usually, where I live, the evening brings calm conditions. But wind started gusting higher causing the lines to sing & the leading edges began deforming. So out comes the B2 mid vent with a 50' x 50# line set with 11" handles. I could launch & fly around a bit but the turbulance from numerous small trees made sustained flight tough. I walked around trying to fly myself into a better spot without any real improvement. It looked like there might be a bit of a wind tunnel where the entrance road came into the campground near our site. I was lazy. I did not bother to wind up my lines to walk across a seeminly harmless stretch of taller grass carrying the kite & dragging the lines. Not too good. So I parked the kite at a good launch site & dealt with the line issue. I knew the lines should straighten out if I kept my head & did the right things. There was a good snarl of loops & knots at the twenty foot area of the line set. I staked the handles & gently teased out the snarl in no time. "Dang, I must be starting to get some of this kite knowledge I've read about!" I thought. The wind blew down the road, through an opening in the trees & out over the pristine corn field. The small flying window was about 30 x 30 so I practiced small manevers & positional hovering. The B2 mid vent is a wonderful kite. After a half hour I heard a toot of the horn signaling me to return to the campsite. Life is good. Next morning we stopped at Antique Archeology then battled the wind driving across Iowa. It would be a couple more days before there was time to fly again. SHBKF

    Friday, March 11, 2016 I set off early in the morning with a fellow kiteflier on our 400 mile drive down to Huntington Beach for Kite Party 14, my first Kite Party. It was raining for most of the drive as a storm was moving south at the same time we were. When we reached the LA area, the rain was so heavy it was hard to believe that the forecast for the weekend called for sun and good kite flying wind. By the time we reached Huntington Beach though, there were slivers of blue sky poking through, and the rain had mostly let up. We paid a visit to Kite Connection on the Huntington Beach pier to meet the owner Dave, who is also the organizer of Kite Party, then said hi to the early arrival kitefliers who were still flying on the beach despite the rain that had passed through earlier. We finished off the day with dinner at Fred's Cantina, where we met more kitefliers who had arrived for Kite Party. Saturday, March 12, 2016 Saturday morning, I awoke to blue sky and light wind. What a difference from the day before. Kitefliers began to gather on the beach for Kite Party. There were two roped off fields for the registered kitefliers to fly in, one for sport kites and one for single line kites. Fliers set up "camp" (chairs, banners, sunshades, assembled kites, etc.) along some of the edges of the fields. There was a fliers meeting where everyone gave a quick introduction, and then Kite Party was on. Since Kite Party was a party, and not a festival, the roped off fields were for everyone to fly in, and there was no schedule. There were always many people flying in a small space, so sharing space was important. In fact, lines were limited to 75' for sport kites. There was a lot of Rev team flying (yes, on 75' lines), which I participated in quite a bit. I took a few opportunities to walk around to the single line field to take some pictures. Jose Sainz set up a banner display in one corner. In the afternoon, we did a memorial fly for Ron Despojado. More than 30 Rev fliers participated, and the line of kites and pilots stretched from one side of the field to the other. We spelled "RON" and made a few balls. With that many pilots spread across the field, instructions had to be passed down the line from one end to the other. After the sun set, we all migrated over to Lamppost Pizza for dinner and the kite auction. Sunday, March 13, 2016 Sunday was much of the same, albeit with a slightly slower start due to the Daylight Savings Time time change. I decided to set up a dualie, but by the time I did and walked around looking for a place to fly, I was feeling claustrophobic with all the kites already flying. I can fly a Rev in close quarters no problem, but I am not quite comfortable enough with dualies to do that yet, so I left my WidowMaker by my kite bag and went off to fly my Rev again. I did find a brief opportunity around lunch time to fly my WidowMaker, so I didn't set it up for nothing. One of the major attractions on the single line field on Sunday was this dragon. I also took a walk on the Huntington Beach pier to get some pictures from a different angle. Somehow most of the sport kites were on the ground when I took the next picture. Kite Party ended with dinner right next to the beach at Zack's, where we said our goodbyes. Monday, March 14, 2016 Monday morning, I looked out the hotel window and saw gray sky and wet ground once again. At least the drive back was mostly dry. We really lucked out with the weather during Kite Party. Ron must have been looking out for us from above.

    Diamonds in the dark Decided I wanted to take my seaming technique to a feasible limit. Using the same materials as the Midnight Royal and Yonder, I went with a diamond pattern and worked it through nearly the entire sail yielding over 450 panels. Encouraged by the mock up, I pressed forward. Once the sides were nearly done I realized how much actual area I had lost with the 1/4' overlap.. i decided to wedge some poly at the top to give it a bit of a retro look. Ready to join the center and make this a flyable sail at this point.. More to come soon.

    Just a short post to talk about getting a new kite! I found a green prism quantum on craigslist while away for work for $60 The owner said it had been flown once but everything seemed brand new including the lines so I'm guessing it was just opened up once or twice indoors. I took it out yesterday and this morning, and it flies great. Interestingly, when flipping through the manual I found out that you can tune the lower yokes on the bridle for "radical" or "forgiving" flight. Both quantums had been set for 'forgiving'. It is crazy what a difference it makes switching things to radical makes. I'm pretty sure I could snap stall in properly strong wind with these settings! I wish I had paid more attention as another flyer at the point mentioned 'cinching up' those yokes once but it was before I knew what they really meant! Here's 6 minutes of me flying yesterday evening with the new settings. I'm still digesting all the ways the kite feels different with these settings but I'll update this post as I have thoughts. It feels like there is a bit of a delay between my input and the kite's reaction, but the response itself is actually more precise. I think this is because the kite 'wobbles' out of plane a lot more easily on this setting. So far I've only tried the radical setting in conjunction with the 'nose forward' light wind bridle setting but I'll try other combinations this weekend I'm sure! Edit: Here is the 'standard' wind bridle (still on radical settings otherwise)!

    The last month has been interesting for kiting! The weather continues to worsen and I find myself having to be much better prepared to go fly. Compared to last fall as a non-kiter I’m now much more sensitive to weather! I didn’t realize how gusty the winds get once summer ends. The erratic rain is less of a problem (at least for the kite), but it isn’t super satisfying to come home soaking wet J. Worth it though, and nothing a raincoat can’t solve. I’ve also moved from walking to the point into a driving routine, and my car’s trunk is colonized by kites and lines. On to flying I’ve been focused on a couple key things each time I hit the field. · Stalls- Getting the hang of these, except for stalls while traveling upwards. I’m not 100% with stalls yet, especially on low wind bridle settings and in winds over 10mph but I’m feeling good. · Slides- o I’m good with initiating slides at the edge of the window but less good the closer to the middle I get. I have come close to starting slides from an axle but it still feels pretty random. o I’m pretty solid at holding a slide, but not at ‘pulling’ the kite past the middle of the window to keep sliding. I have pretty much no practice sliding from the center to the edge of the window. · Axles- I’m trying to develop a solid feel for the range of inputs that all result in an axle. It seems like you don't have to be totally stalled to do an axle, but you do have to be able to give the kite lots of slack after tugging. Being stalled lets you really push back the wing which I think sets the kite up better but I'm nott toally sure yet I think the 'sharpness' of the pull makes much more of a difference than the intensity. I can axle with one finger no problem this way. On the other side, a longer pull almost always ends in a wingtip snag/wrap. Even when the tip doesn't wrap, long pulls rarely get the kite to rotate all the way around. I think the intensity of the axle input determines how quickly the kite rotates, and how far the kite falls (or rises) during the axle. I’ve noticed that in low wind you can actually lift the kite with an aggressive enough axle. I’ve been saved from the lack of ground-level wind a number of times with a nice fast axle! · Fractured axle-to-fades- I know what I’m supposed to do, and I know thee ‘lock in’ feeling of a well-executed FA. Flatter axles would help, as would better timing for the pull (my videos show me this is my biggest problem). I’m also still learning how much slack is ‘just right’ so the nose doesn’t over-flip. · Cartwheels- I think I’m good with these now, though they aren’t pretty yet. At least I’m doing the walk of contemplation less. · Fade launches- It might be that I’m always practicing in pretty low wind but I'm finding fade launches tricky. It seems like as long as I pull out of the fade the instant i enter it that I can fly off most of the time. I'm pretty bad at maintaining the fade near the ground still though. · Half axles- phew, what a challenge still. I still don’t really get how they should feel. I can pull the top wing down into a ‘flare’ like position (but with the nose pointed to the edge of the window). I can even sometimes then pull to rotate the nose around the other way, and even fly the kite out of it sometimes. But it doesn’t feel or look anything like a half axle. I met a flyer at the point who is great with slack line tricks!! I watched him for awhile and felt like just doing that taught me lots. I think my problem is that I'm not 'snappy' enough with the input, just tlike with the axle. I tend to try and pull the kite right into a flare which I think means I'm pulling for too long. I feel like I was getting closer in this last session (with my I2K) until I broke a lower leading edge... I think it must have been broken when I got the kite as it was a soft crash (landed on both wingtips but with some sideways momentum) that popped it. New parts are waiting across the border for me and I can pick them up today in Blaine · Air recoveries- Exult’s blog talks a lot about “provoking the kite”, and how it gives one a chance to feel how the kite responds to inputs from a variety of positions. I’ve noticed that when the kite starts to tumble, 9/10 times it can be fixed by walking backwards a few meters! If that doesn’t work I try tugging one line then repeating the backwards walking. I have no idea how to save the kite when the line snags on a tip, but at least I can guide the kite gently to the ground when it happens. Between the ground recoveries, air recoveries, and axles I’m in the air and actively practicing 5X more than when I first started leaning the axle. I’ve really noticed this in the videos! Previously I might get 10min of good footage per hour of flying. Now almost the entire hour is usable. Reviewing this footage has been so instrumental in improving my skills so it is nice to increase its information density! I’m also spending more and more time in a stall/slide and less with the sail ‘powered up’. I'm slowly improving with flip tricks too! I can finally turtle, both while flying upward and a 'snap turtle' while flying horizontally. I'm still not great at maintaining a turtle. I went out a few times to try night kiting! My BF brought home a couple packs of LED fingers from the dollar store which worked really well! They are a bit over 6g each so they don’t add too much to the weight of the kite. That said, with one clipped to the spine and one on each wingtip the kite controls pretty differently! I did my first (cruddy) multi axles within minutes of being airborne and weighted. I’m now playing with keeping one clipped to the spine in medium and stronger winds. I also want to play with nose vs spine weights! Finally, I'm playing around a bit with the way I film and edit my flying videos. If I put a camera close to me as well as one behind the kite I can make some 'overlays' that better show off my hand movements. I don't think I'll do this every time but I learn a lot about what I'm doing wrong when watching these!

    Winter isn't so bad here... I just wish the sun would come out more. 34* F and a 8mph breeze keeps most people away from the beach. I think I saw 5 people in the 3 hours I was there this morning. 3 hours of peace & quiet, enjoying the solid on-shore winds... I could've stayed longer but the urge to eat & find a bathroom won out in the end. The Ultrafoil 15 got tied off to a memorial bench. I flew it nice & low so I could practice flying the Rev next to it. It's great fun to steal the wind from the SLK, watch it fall, then regain it's shape and soar up again. The other kites of the day... the SkyBurner XXL and Mid-Vent Rev. The mesh hasn't totally torn out on the Mid-vent, there might be a few more good flights in it before it gets retired to the repair pile. Still working on flying the Rev with one hand... not much progress in that, once I get too high, I freak out and have to land quickly. I get about this high, and have to land before getting too far out of control. I've been thinking about linking the handles together with a cross of some sort in order to make 1 handed flying easier... I wonder if that's been done all ready ?

    For the longest time, I was my own worst "block" to advancing my skill set. Starting out I quickly learned when I could fly and when I couldn't. As my skills came along I fell into the "comfort zone" and basically stuck to that wind range. Sure, as I got a vented sail I would venture out in the higher winds but still stuck to what I was comfortable flying in. Comfortable. I was stagnating. I started to wonder if this was it. I began to make those excuses we all have done. Not enough wind. Too variable. Too tired. Then my work and family responsibilities began to creep in. It became easy to go "next time". Then I began to alter my perceptions. My mind set. I had light wind kites so I had the low wind equipment. I saw others fly in ultra low winds so I new it could be done. I stopped making excuses and started to apply my skills to fly outside my comfort range. I got over myself. Half an hour every day after work and one week I began to feel very comfortable in low low winds. Eventually was able to fly in Zero. And with that came a mental change. If I can fly in nothing then I can fly in anything. Anytime. Just like that! Low winds are no longer no fly days, they are a chance to advance my skills. Dirty air is now a challenge not an obstacle. Dont accept the conditions, adapt to them.

    While driving down the freeway I spotted someone flying a Revolution kite at Riverview Park. I had to stop to meet this person. His name is Geoff, he purchased his first quad line kite after seeing my "First Flight" video on youtube. Geoff drove to Riverview Park in hopes of running into me, using his kite as a signal in the sky. We have kept in touch for a few months and in that time he made his own kite! We are putting together measurements for new kite designs. An Arizona kite making community is born. 2016 is going to be a great year!

    Since the new year, I've turned my attention to materials other than tails.. Nothing wrong with the tails constructions but I wanted a new perspective.. and that perspective was perspective.. Angled shapes started out as a lazy harlequin pattern in complimentary colors. Because of the pattern it became the Jester. This was my first run at edge joining materials that were not already hemmed. The Jester followed by a vanishing point perspective in dissimilar materials. Because of keeping the grain of the fabric somewhat aligned for Midnight Royal Taboo, those strips fit together in a B2 sized kite I call Yonder. (Those that participated in my Christmas riddle got the reference right away) Finally I went back to the Jester color scheme and created a new kite experiment with 2 perspective.. I suppose this was also inspired the cubic look of some of the @Polo design. The sail shape tens to lend itself to the dual perspective images in a somewhat natural progression. . Going with the Jest from Jester and the obvious checkerboard effect, Jest Checking In is laid out and ready for sewing. Enjoying the way it truly bends the eyes, I decide to move the vanishing point to the bottom and the center instead of the top. While I have to finish one kite before I lay out another, I did use the small endpieces you see in the Jest Checking In picture to mock up a 70 panel version. Nothing precision here, just wanted to see if the pattern will stay consistent. It was pointed out tp me the points of the pattern don't line up perfectly. and I will acknowledge that fact. My goal here isn't perfection but effect. It has to look right at the end of the lines.. the overlap for the long angular strips (in all three kites since the Jester) is 1/4" those angle just don't line up when you slice and overlap them in a different direction.. but at 100ft the effect is still there so I'm happy with it.. I have a bit more of the orange and blue so a large triple perspective will probably be next but I want to finish what's laid out before going down that route..

    Suddenly, it's May! The weather has been turning colder here over the last few (eight!) weeks. Work has been busy, and combined with the end of daylight savings time, it has definitely put a crimp on my flying! I finally got a chance to debut my new ribbon tails last weekend, they looked great! Unfortunately I can't show you any video, the GoPro wasn't working properly - operator error! Then I got rained on and it dawned on me that I now had to work out a way of drying 2 x 25ft tails... The answer I settled on was pulling each tail through a folded towel, that seemed to work pretty well! I managed to put my first puncture in the sail, but my kite repair kit came to the rescue and it handily patched the small hole before it had the chance to become bigger. I got to go out and play for about an hour the following day in about 10 - 14 km/h winds, I had a lot of fun just keeping the kite in the air and moving it around in the window. Nothing fancy. I need to go back and review all the slack line trick videos again before I go out next time, that wind speed seemed ripe for trying a lot of tricks.

    We have had a few pretty days here in the valleys of western Virginia. It even hit eighty degrees for a bit this afternoon. So spring fever has everyone in a good mood round here. Then you feel a nice warm breeze blow late in the evening. And after a lot of work you may somehow get to the point that you're saying to yourself "Why am I doing this? Might as well spend some of the hard earned money, on a, on aahhh, another kite!" Just one more, don't really need one but why not. So it goes when you have this addiction. Later, at home, you check KiteLife to see what's going on. There's a post about a kite that has been for sale for a bit & now it's been endorsed by a Master Flier. It's one you have always been curious about. And it just happens to be a SUL version which will be perfect for the summer lulls that follow spring in these parts. Nice looking, excellent condition, good price & a great seller. What are you waiting for? Jump on that thing before someone else goes through the same thought process. Right. It's similar to the sequence of rationalizing another great kite that has occurred right here in this chair more than a few times. So it should ship in a day or two. Does all this sound somewhat familiar? Or maybe I'm alone in all this kite quest thing. SHBKF 3-14-2016 So it arrived today....

    Down here in Oz we have just turned the corner into Summer and I'm hoping to be out a lot more during the daylight than I have been. Where I live we have this belting Easterly that comes rushing down the escarpment making a Vented sail pretty much the only option. Then tapering to NOTHING around midday giving the SUL and Indoors a go. Then early evening "the doctor" comes in to provide some respite from the heat and lends itself to Standards/Mids. Literally an entire bag could be used in the space of 24 hours. Due to work and family commitments I find myself mostly flying at the "unholy hours" of early morning. 2 or 3am is nothing new. Quiet. Peaceful for sure. Lonely, you bet. Not many flight buddies at that time. It does open up some opportunities that normally wouldn't be there during daylight hours. Shopping centre carparks are empty. Playgrounds and basketball courts are vacant. Shadow flying on great big walls using the floodlights is immensely satisfying. Always scouting for the next "after hours" site.

    So it's four in the morning, cold & raining here in the mountains of Virginia. And I am reading KiteLife & thinking about kites. I thought kites might be an interesting thing to get into again a few years ago. Knew they were an old passion but did not think they would dominate me as they have. So now, for what it's worth, I will attempt to have a place to ramble on about my thoughts & efforts along the way. Just got back from an extended beach trip. Even the beach has less than great conditions many days but all the inland flailing I've done payed off & flight was continuously possible out on the sand. Got some new kites but did not fly them. Flew vented kites the first few days & then SUL's as the conditions changed. But that's past & I think I will just talk about the moments of kite flying as they occur. Later....

    So I found an older colorizer over on GWTW and adapted it for the diamonds design.. It's not web based but gives me a pretty good idea of how I can set up my color schemes. Here are a few quick samples.

    So I came to a rude awakening yesterday.. Despite my best attempts, it's really hard to get all my framed quads in an easy configuration for travel.. Part of this is because I don't know how to leave ANYTHING behind.. Given that I've made a bunch of kites since my last outing to OBX, I decided to make a dig bag. I came up with a 11"x11"x44" pumpkin of a bag after visiting Joann's Fabrics this morning.. I picked up some Orange duck cloth and zippers that all combined with a tiedown strp I had handy to form this bag.. Definitely a first effort but also a usable item.,,Lots of space for Revs, Freileins and home mades. So far, it has my home made rolloup bag, My Freilein Dig bag with all the Revs and both the Freilein and Spectrum stacks inside with room to spare.. Pretty sure it will hold ALL of my framed quads without breaking a sweat..

    Mars 2018, ITW Kymera 25m lines One, lately a bit rare , pre-work session on a piece wise slippery field. This morning offered a sun dog scenery along with a faint halo. My current DLK main focus is to get the flic flac going/start/getting a tiny bit reliable. Considering that the FAs are not 100% it is actually more than one thing that is being practiced in parallel. Sometimes even one rung of a JL just happens to come out of it (typically if the light pop when flared was uneven and you happen to end up in a turtle). It is kind of a continuation of last springs "tricking en masse" (~keep the kite unstable and let it tumble around without the lines getting tangled) project, but perhaps/hopefully some more intent shows though. This focus (and also the, to date, three quarter of year of QLKing) means that other tricks get less attention, so I guess that (if the above would get successful), the next project could be to make earlier tricks (now more neglected) to co-exist - all available simultaneously. First image: Notice the sun dog and a faint halo around the sun. Second and third image: I like the mood of the greenish toned winter. In addition the green themed Kymera goes well along with it. However I can't say if the reddish or the blueish image from the same session is the truest one. Beginner flic flac problems: Feet stopping when they should be running downwind typically during the flare after the first fade. Sometimes the kite just gets towed instead of exiting the fade (to flare) - it is getting rarer now though. Sometimes the short tug that ends the flare is un-even and "un-planned tumbling" is initiated. Not really knowing the details to look for or feel that should trigger the movements when doing the trick (but I just recollected the hint about looking for the spine in http://kitelife.com/forum/topic/8554-zephyr/?do=findComment&comment=69059 , so that is something to try). Sad news: my Infinity starts to get worn. Good thing: In the often light winter winds the green (for some reason I currently seem to fancy green) ITW Kymera is a good option for the flic-flac training. Even though the Infinity was the kite that first allowed me to do a few flic-flacs, the Kymera allows me to get the same training in somewhat lighter winds. These finger straps are OK once when they are on, but it is tricky with gloved hands to get fingers in since the straps have a tendency to go flat. The now not so cold weather allows the easiest approach to get the finger straps on and off - just take the gloves on/off when before/after the walk of shame/contemplation.

    Sat Sep 30 16:38:39 CEST 2017 GF, forecasted 3-4m/s Fazer XL and XXL stacked on 35m 180kg lines Two 23m (75 ft) prism tube tails To carry stuff After the soon 3 months on QLKing I decided to end that test/project and return to DLKs (and "at the same time" continue with QLKs). During the QLK time I got kind of "transportation spoiled". I only had two kites to carry around: B-series 1.5 std and full vent. The full vent venting holes are patched with removable thin sheets of cellophane attached with (centimeter wide strips of) tape.* Included in the package was two, three and four wrap spars, so these two kites could handle (well could be used by me to practice at least) all the wind conditions that I met during this period. The two quite small QLK kite sleeves were tied together using the strings already on the sleeves (the strings normally used to close the bags i.e.) and hung comfortably over the shoulder and backpack during transport - it wasn't even necessary with a kite bag. Today however the ski bag was the available option to carry the Fazers, the tails and the QLKs and a few line sets. Suddenly a 5.5 kg (12 lb) ski bag was hanging on the shoulder again. * The second iteration of cellophane/tape patching would be to make the tape strips towards the LE somewhat wider. The reason for this is that sometimes I need to press it at the start of the session and possibly one more time to make it stick well. Hopefully the wider tape closer to the LE would improve things. The tape used here is intended for large sheets of polyethene/polyethylene used here because the glue has never left any residues for me. Preparation, making and repair This the first time I pilot a stack or see any stacks of more lines than one. Some info on how I made it can be found in in http://kitelife.com/forum/gallery/image/6234-stack-work-in-progress/ : The stack was made earlier during the summer. The kites themselves have also been resting for more than half a year. Part of the reason has been broken stand offs that had snapped/cracked. The reason why only the Fazer stand offs are the only ones that snap for me is due to the often long line lengths making it difficult to see if a line is wrapped around a wing. You also typically pull harder when starting, meaning that if the line happen to be around the wing the stand off is more likely to break. This Fazer XL stand off was damaged during a start resulting in delamination and snapping fibre (bundles). Could tape keep the fibre bundles together and work as a mold during the repair? Nope, the tape mold approach didn't work out well. The resulting surface was very rough - best seen in the shadow edge. And, I really dislike sanding down glass fibre - itchy, itchy, itchy! The Fazer XXL's stand off was instead repaired using heat shrink tubing. Here the heat shrink tube and epoxy repair had to be split into a two step process, because the cracks were long and the tubing could not be slid over the ends of the standoff. Look closely and you can see that the first step is already finished. No sanding required when heat shrink tubing was used. The pin was not absolutely straight afterwards. Using some kind of a alignment jig would likely have produced a straighter result. To the right you can see the hot air gun used to shrink the tube. The dog in the background might look cute, but is really internally about to explode: "The BALL, the BALL - STUPID!!! Can't you see the BALL stuuupiiid??!!". She might not be of much use when it comes to get work done in outdoors (making you feel bad for not playing with her constantly), but at least fanatically returns any tennis ball shot if you work on your serves in the garden. When playing with (stealing from) the German shepherd she wins by outmaneuvering, even though the German shepherd runs faster when running in straight line on a field. A very never ending playful dog! I decided to try to repair the stand off rods themselves instead of making new ones. I believe that there are several benefits in getting better with epoxy and fibre repairs (or other plastic fibre composites?): if spares/spars break at the wrong time and you don't have spares you have a way out, the feeling "I did this" instead of buying, if your kite ever would require no longer available rods, doing composite repairs could offer a way out. I also consider (/an idea could be) to increase the strength in LE of DLKs just to make it more robust when tip stabbing etc. or if I ever would come to the kite surgery of making a frame lighter. Spars are often uniform throught out the length, while the loads are not. You can have an extra high load in LE connectors or just below the LLE/LS-connector e.g. When it comes to keeping the fibres (somewhat) together, squeezing out excess epoxy, speeding up the curing of the epoxi and minimizing the after work, heat shrink tubing rules and tape "sucks" (to my somewhat limited experience). A requirement is that there is enough room so that you can slide the heat shrink tubing on and it shrinks enough. Tape however is good for masking - covering places where you don't want any epoxy. A common type of heat shrink tubing shrinks to half of its original size (1:2). You can however get hold of (in shops like (Farnell, RS components, ELFA, etc...) sorts that does 1:4 and 1:6 shrinkage at various temperatures. Out on the field The stack. The wind was a bit on the lower side for the somewhat heavy Fazers. I had to work a bit to keep them in the air. After briefly testing the XXL just to verify that I remembered the DLK (Fazer) control well enough (after the DLK pause) I assembled and connected the XL to the XXL. The result was surprising - it just worked out of the box! I didn't feel that it was necessary to do any tweaking. On the other hand one of the to sources of how to do the stack lines was KL so the bridle should be just fine. In the stack the XXL nose was tilted backwards about a centimeter relative to the XL. The stack line connectors on the Fazer XL were prepared for further adjustments, but it didn't seem necessary. The XL had a slight tendency to wobble a bit during most starts, but was quite well behaved otherwise - unless you are "asking for it". Perhaps not so strange oversteer has always been a "hallmark" of the (my?) XL. It is not such a bad thing once I learned to handle it. During windier days I'd say the XL got the temperament of a leaping calf that suddenly can grab you and make you end up three steps downwind. Only one time during this session I was a bit surprised when the stack fell out of the sky after a snap stall. Unless provoked, the kites flew synced, albeit the XL got some oversteer. The main goal of the day was to get the stack working and if it did, try it with the tails. In the a bit low wind and new circumstances I limited the flying to figure flying (how much more than that can you do with a stack b.t.w.?). Only a few times I had the privilege of being dragged by the stack. The most trick like I accomplished was a cart wheel, which demanded a bit more persuasion than usual to work with the stack of different sized kites. Side slides were also possible. Well another thing, but I don't know if you can call it trick-like, was when running quickly backwards to stabilize the stack in the low wind during a start, which caused me to fall backwards like some fall in a Laurel and Hardy movie: Even though I somersaulted backwards on the ground over one of the shoulders it didn't hurt. I guess the pull from the kite limited the speed of the fall. Unfortunately I don't have any photos of the stack in flight. The tails were attached to the bridle of the XXL where the LS meet the LE. Visually it would have given the same effect if the tails were attached to the wingtips of the XL. The perspective I had of the kite almost made it look like one kite except if the XL was oversteering/wobbling. Otherwise the size of the stack, long lines, double tails and slow flight gave it kind of dignified look. The effect of the double tail when doing tight loops was however a bit of a disappointment (slow turns of forward travel looked great though). The inner wing tip and tail hardly moved. Moving the tails inwards to somewhere closer to the stand offs could be one way to make the tight loops look better. Another way to make the loops look better could be to attach one tail to each spine (should at least be interesting to see from the side). Perhaps tight loops with the current position also looks better from the side, but piloting the kite meant that I hadn't that view. The position of the tails can be adjusted to make the tight loops look better. Forward flight looked good (as seen from the pilots view). Future The Fazers are quite robust (heavy). One project I consider (i.e. I like the idea but it is not very likely to be implemented) is to make an extra set lower spreaders to use in lighter winds. The diameter of the current ones are 10 mm for the XL and 12 mm for the XXL. Preferably, if it would be good if it would be possible to get hold of thin walled tubes of the same or larger diameter so that the stiffness of the tubes didn't go down too much. What I really would like to do when I "grow up" as a kiter (if you can ever do that with kites) is learn how to handle my sewing machine well and for some reason get an enormous amount of spare time. Then I'd do a kite based on a truss construction ( https://en.wikipedia.org/wiki/Truss , https://en.wikipedia.org/wiki/Forth_Bridge ) instead of single spars. A starter project could be weight reduced spreaders for the Fazers. The weight of the Fazer XL spreaders, 1 TS +2 LS, (according to a very old scale) are 190g for the Fazer XL (680g for the whole kite incl. the stack bridle connectors, total weight according to the Fazer XL datasheet is 615g) and the spreaders of the Fazer XXL are 410g (1305g or 46oz for the whole kite including stack lines and end caps, literally "~xxx g" in the Fazer XXL datasheet). A truss shaped spreader could have a smaller cross section area, while the larger total diameter prevents them from flexing out sideways during compressive load. The, still dreaming, project after that would be the all truss and all mylar sail kites. On the other hand (still sticking to large kites) acquiring another large kite (like Topas 3.0 or Hot Stripe XL?) could get the diameter of the spars down and hopefully the kite up more easily in low winds. No I haven't done much research here - sometimes you just want a kite. No I don't think that I'll fly this stack very often. I miss the tricking possibilities to much. My plan is to get somewhat more acquainted with the control and also to see how much wind I can handle. For next years kite festival the stack is a possible contribution, provided I can find a good place with good winds a bit from the centre of the festival and with not to many people around. Although there have been no good multi line kites during at the festival the two last years (which equals to the times I have been there) I like to increase the competitiveness (yes there are a few prices) by always offering something new and most likely put a tail on it. Does this approach have a light scent of crowd-pleasing? During the last festival I handled it in the following way: Before the price ceremony I flew dual DLKs with tails and after the ceremony I did DLK (one kite) tricking to also demonstrate that aspect of kiting as well. If there would be room for the Fazer stack at the next festival I'd say that the odds look good - the bystander interaction today consisted of three chats, while the usual number could be a chat perhaps every third time. When walking of the field after the 4h stacked session it instead felt like after long day of outdoor (garden/house) work. It was early to bed that night. A slight muscle soreness remained for a few days after as a receipt of that kiting can offer good physical exercise.

    My first pre-work session May I ask for 10 more of these sessions? Fragments to decipher - tricking that leaves questions These sessions were all in the tricking en masse spirit. Approaching tricking from this different angle turned out to allow me to catch glimpses of tricks that if I would have worked on a trick methodically one by one, would have been several years ahead. This once again leads me into thinking of the beginning of the Trickery Flickery video ( http://kitelife.com/forum/topic/3477-trickery-flickery/ ): "Once you understand what to expect, you then start to be able to control these and then they become moves". I hope that I'll be able to benefit from the insights/samples gained. Yet, I'm not a believer in some only way that does it all. More grabbing bits and pieces of trick learning by applying several methods. The schools in Stockholm have their sports leave during week nine this year and also at work some have left for typically a week in some ski resort. We (my family) did "our trip" during in December (less crowded then), so we remained home now. It turned out that I didn't need to go far to do sporting of the kiting kind instead. ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ My first pre-work session Tue Feb 28 09:22:43 CET 2017 GF forecasted 4m/s Kymera on 25m 38kg lines OK, I've reached a new level of nerdom today. Tennis training is cancelled two weeks in a row, so therefore, I figured instead of being late to work because of playing tennis, I could do some sport kiting! Observations from the flying were not that many during this shorter session (can't be immensely late at work). The little longer of my line sets that I most often use served me well. The winds close to the ground were a bit low and slightly turbulent. So, a bit higher up in the wind window (one time) a cascade attempt (only like two half axels or so) was unexpectedly soft and floaty. Could I hope to repeat this? Flying with the Kymera, for me, I need to actively strive for the "tricking en masse" practice that I rather recently decided that I would try, because the figure flying with the Kymera is tempting because it looks good. The walks of shame were frequent today, but is something that needs to be accepted when trying to trick en masse - Welcome the walk of shame! When going there I two times crossed the cross country ski tracks but I thought I was alone. However two "pre-work sport extremists" of the skiing type showed up later. Moving backwards and forwards was somewhat restricted by ice. It was more ice on the side of the ski track that was lower than the track where one would expect the meltwater to go. Unfortunately this was the place that suited the wind direction best and was quickest to get to during the limited session time. ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ May I ask for 10 more of these sessions? Wed Mar 1 09:04:26 CET 2017 GF forecasted 4m/s Hydra on 25m 38kg lines I can wish no more of a session than this (apart from that it should have been a little longer). The wind suited the Hydra perfectly and the lawn was well cut and free of ice. To describe it, from on-ground nose down, you could just force the kite onto its belly when being supported on the LE, so that a fade launch could be initiated quickly - no running up or downstream was required. The morning sun shone occasionally on my back. Today I was in the middle of the ski track surrounded by several skiers that also had discovered the nice weather. The session felt like a step forward in the en masse tricking - tricking with little rest - keep the kite out of normal flying. I believe that I was helped by the good conditions, the little higher wind than yesterday that suited the Hydra better and also that the Hydra seems to accept much tossing around (thinking mainly of cascades here). I got the (snap) lazy susans going (also) with the Hydra, and that felt good. The trick seem to be - don't wait after the snap turtle - just do the lazy quickly. I should experiment if I could lower the nose by moving forward however to see if I could do this trick more calmly. The exit was often a bit early so I need to work on this as well. Today's highlight was the cascade. It could go on until I lost count and then flew away without the ending in a turtle! Realizing that the session time was limited I started to instead do the run of contemplation (well I shouldn't over emphasize the the contemplation part - the thought was simple: "Get that kite up and that quickly"). If this instead had been a "marathon session" the run of contemplation would have been pointless - frequent running would just have caused a pause of rest/inactivity. Another good thing was that a few of yesterdays softer cascades happened as well! This tricking en masse that I currently try to do, I believe that letting go of the setting up and analysis offers a new way of learning for me. For some reason the cascades seem to go on (for today and this kite) - perhaps I can figure out why one day and then learn the difference so that the half axeling/rixeling get predictable/controllable. If I manage this, then my hands has taught me how to do do a trick (well at least on the Hydra). One end of one of the mini battens was found to be loose - when/how did this happen? So weren't there any not so good things today? Well the FAs and the belly launches weren't reliable. The tricking en masse leads to more walks of contemplation (but I think when learning/discovering new stuff the walks are inevitable). I also discovered that one of the near-the-wing-tip-mini-battens was only attached on one side. When you have this perfect session going, stopping for going to work is not really at hit. On the other hand it might be more efficient per hour than my usual session, often ending in the dusk or when my wife reminds me of today's planning ( ...Now!). Talking about my wife, she didn't know that I went here before work because I left home much early. It looks like that I've sunken deeper into the kite swamp. When almost everything is going you way it is so tempting to continue the session - but NO this alternative wouldn't be reasonable today. The number of morning skiing pre-work extremists were even higher today. I deemed the best spot for kiting was in the centre of the ski track loop. One of the skiers is can be seen in the background. ¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤ Fragments to decipher - tricking that leaves questions Thu Mar 2 09:21:12 CET 2017 GF forecasted 2m/s Hydra on 25m 38kg lines One lesson learnt - don't put absolute trust in the forecast (even if checked just 1h before!). I'd expect that on this field 2m/s would have meant the HQ Shadow - not the Hydra. Small intrusions and large intrusions. The GF field gets nibbled, a playground, (artificial) beach volley and areas for vegetable plants reduces useful area and makes it somewhat more difficult to find good wind. Another field just south of Stockholm has really fallen victim of some landscape architect? There a 400m large "ring of evil" has been created by planting trees in a circle covering much of the field. There is some campaign going on to save this field from other use, but whether they think anything about the trees or not I don't have a clue. I have not tried this field so I don't know, but that ring just can't be good news. Besides, it seems to be every landscape architect's duty to plant trees the instant they see water. Here in the inner parts of the archipelago the nature itself grows trees all the way down to the water making the kiting fields close to water very few. The erosion from the water is also small so the zone without vegetation (beaches i.e.) is very small as well. When randomly doing axel-like inputs, I sometimes get a very soft axel going beyond the "natural stop", but doesn't fully double axel. Should perhaps compare this to the double axels that the (Prism) Alien does. The turtles lasted for some period for some reason. No I can't say I understand why and I didn't actively do any attempts to control the pitch of the turtle during this session. Another trick to be deciphered from today is a rolled up fade launch. After a failed low sloppy snap lazy I ended up on the ground. The kite was rolled up in such a way that when pulling the lines it rolled up on the ground and did a fade launch! It happened twice! It is like certain codes for entering doors - You can't picture fully was happened, but you know what to do when you are standing there, it is the situation that triggers the memory/action - the next time I'll try to observe and remember more "theoretically". ... (one night's sleep passed, in the morning I think that I sorted it out how it "must" have happened): After the failed snap lazy, the kite had ended up flared on the ground with the lines (starting from the kite) going over the trailing edge, then over the leading edge and then on the ground - i.e. rolled up once (the back-flipped rotational way). The un-rolling/launch was performed by a non-hesitant but not too hard initial pull, followed by just maintaining a faint line tension (like when maintaining a fade). It was much like a fade launch, but the lines wrapped over the kite forced the nose down and under into a fade. How to repeat the snap lazy "failure" to be able to to this fancy start again? One line under the wing and one line above being held by a yoyo-stop. Is there a way out this snag? If the Hydra now provides me with tricks during tricking en masse that I don't fully understand yet, its bigger brother, the Jinx should be slower and could perhaps give me the time to decipher it? When checking the fortuna-forms (.com) website it seems last updated in 2014 and the offered Jinxes lacked specifications (so also the reviews in Kiteclique). If I only could make my wife convinced about the great thing in buying an American kite (or actually any kite) again - already as it is, buying/importing a kite directly overseas would add tax and more expensive shipment compared to buying within the EU. If the trade protectionist climate would further harden and also be met with counter measures one short term effect could be that a kite import here would be even more expensive. Being very optimistic this actually could provide a temporary opening for getting the Jinx: "Darling, don't you reeeeaaaaly think that I ought to get that Jinx kite before it might risk getting more expensive?". Kites might eventually be somewhat more confined to their region of origin on either side of the Atlantic. On the other hand, making predictions is very hard, especially those about the future. Unfortunately it also seems like I moved too slowly, the Fortuna Design page was no more when checked and also when verified again. Well I guess I shouldn't be considering new kite purchases for some time now anyhow (at the time of posting this blog entry I've already failed doing so horribly). So in the end I think I'll invest more time in kite repairs to see what I think of them after the time that has passed since I last used them and having learnt more, thus postpone purchases for now. I discovered today that the clip preventing the centre-T from moving is completely missing. Hopefully I can find the marks of the old one, so that I know where to put it. Or rather, go for a double clip - it is not the first time that I've had them sliding and damaging the sail. I guess that the rip could be repaired with a dacron patch. I wonder what type of thread that should be used for this? The image is from a later date when the ugly tape field repair had slided.

    Being relatively new here I'm not yet familiar with all the features/functions of this site. I kind of "discovered" the blog section quite recently and then figured out that ... hm... those earlier lengthy posts (like http://kitelife.com/forum/topic/7093-welcome-exult/#comment-57515 or http://kitelife.com/forum/topic/5459-what-do-do-in-high-wind/?page=4#comment-57785 ) might better had been put in a KL-blog instead? Even after a month I'm still in the process of finding my way around here. Agenda (as of now at least): I aim to cover parts of my dual line stunt kiting here by now and then sporadically writing reasonably well edited posts and blog posts that I would like to read myself. English is not my native language though. It is not only finding expressions that are spot on (which can slow down somewhat), but also avoiding unintended alternative meanings of words. E.g. the name I first intended instead of Exult turned out to be dubious I believe. Quite often I check what happens to the kite when you make a short flick on the lines in various situations without much subsequent feed back and try to see what the kite wants to do. Therefore I thought "Fling" would serve as a good descriptive forum name that describes the kites movement after the short tug. However, after carefully looking it up, it turned out that the alternative meaning might make it a good name in some other type of forum, which is very far from what I intended. Reason for limiting to dual lines is because that is what I happen to do and know. Currently I feel a four line would distract to much in learning tricks at my current level and also from to some more extent for apply the contents of John Barresi's "Kite Flying with Intent" ( http://kitelife.com/kl-archive/flying-with-intent/ ) for my dual line kites. Later when reasonably through (???) with this I'd perhaps feel more ready for a 4-line challenge. Another aspect is, in a time that still feels distant, I imagine that 4-line kiting might add a few more kite active years. Dual line slack line tricks can certainly demand that you rapidly run downstreams, which at an age no longer might be possible. When I come to think of it, there is more old but reasonably recent stuff that could make it into this blog, like this (second) e-mail to Invento-HQ and a kite retailer/source of mine: There was no reply. OK, HQ is not a kite forum and might need to focus on working to get the bacon on the table.

    Not much wind today. But it was so pleasant out that I just had to fly. This is my lightest wind Rev. With a set of diamond rods in it. Flew it on 80 foot lines. In the thermal gusts the wind went up to about 8 mph. Otherwise it was light and variable. Good day for that slow backwards walk then floating forward to gain ground.

    The weather for the weekly kite club fly was once again unfavorable. So instead of flying we went to the kite shop to visit with other flyers and see what was new. The problem was there was something new and I ended up taking more kites home with me. Check out the following blog link to find out what is new in my kite bag.

    Added 21st of June 2018: So in a way @RobB was right, the repair didn’t last. Well there was no catastrophic failure, but a new fissure emerged (still using the tube though). Today I'd increase the glass fibre content. For images and the second iteration of the tube repair including heat shrink tubing (and more) see: https://kitelife.com/forum/topic/8458-widow-ng/?do=findComment&comment=68307 https://kitelife.com/forum/topic/8458-widow-ng/?do=findComment&comment=68335 # Original blog entry from 2016 below #### After a too hard ground contact with my HQ Infinity there was a set of small about 1.5cm (~1/2 inch) long fissures parallel to the axis on the inner end of one of the lower spreaders. This is a description of how I repaired it - not necessarily the best way. If you consider to use other fibres I've written down what I learn't in a comment to the previous blog entry "An Infinity...". Feel free to comment in (close to) any way. Material: Nitrile gloves (epoxy is not healthy) Sand paper Glass fibre - here is long fibre strand used (but I suppose a thin mesh/fabric would do) Tape Epoxy Spatula/flat pin CA-glue Wire Scissors and a hobby knife Nice to have/possibly needed: Hot air gun Heat shrink tube No snug fit - The fissures caused a play when connected to the other LS via the (normal) DT-15 connector rod. Also click on the image to see the small fissures that should be visible in the image then). Using a wire to compress the expanded/stretched opening while pre-gluing it with a small amount of CA-glue. Verify that this part goes well enough before proceeding. When I tried it the result at this stage wasn't perfect, but it tuned out quite OK in the end. Sanding the surface to remove varnish (if any?) - is this a necessary step? Tape the parts of the spar that you don't want to apply any epoxy to. The simplest way to extract the glass fibre strands was by cutting parallel to the strands to be extracted. Limiting to one cut minimised the number of itch inducing short glass fibres on the loose. Before cutting the strand loose from the fabric, put a droplet of CA-glue on either side of it to keep it together, before cutting through the strand/CA-glue. A 3dm long strand was extracted. The damage to the welding sheet was reduced by making the cut in the double layer fabric close to the end and then sealing the hole with a strip of gaffer tape. The sealing of the hole also reduces the number of exposed fibre ends. The way I tried initially to cut one strand end and then pull the strand out step by step using a needle, only resulted in a several places broken strand - not recommended. No the image does not show a broken fiddle stick - it is another old broken (pultruded) carbon tube (used for a practice repair) - here with a CA-glued strand attached. You could of course use tape to attach the strand as well. Wear rather thin nitrile gloves (really not worn or with holes in them though) when handling the epoxy so that you don't lose precision. Be in a well ventilated area or outdoors. Now mix a blob of epoxy with the spatula. Coat the area on the spar with epoxy by smearing it out. Soak the strand in epoxy by dragging it a couple of times through the epoxy puddle. Now roll the soaked strand around the tube to be repaired. Connect also the free side of the strand, so that it doesn't attempt to unroll itself. Add some more epoxy and/or smear/make it uniform. Let the epoxy harden. Cut and/or sand points of the repair that you suspect will point out from the second layer of epoxy. Mix some new epoxy (not much required) and apply the second layer. When the epoxy is almost hardened, remove the tape. The tape closest to the repair might need to be cut using a hobby knife. If the epoxy remains (already solidified but) slightly sticky longer than your liking, have a go with the hot air gun gently for a couple of minutes. At this stage the repair was finished. I was a bit concerned that the diameter of the tube after the repair would be a bit to large. When connecting the two lower spreaders together, the spreaders could be wiggled so that the outer tip could be moved (like a flapping bird) about 1cm relative to the other spreader. However when comparing this to my (still intact) Maestro 3 the amount of play was very similar. If it would have been necessary to handle I would have tried to put some heat shrink tube around the connector part of the other LS to act as a cylindrical shim making the spreader to spreader connection play free. So far I've tried the Inifinity only one time after the repair in quite light wind due to the winds lately and I might have gone slightly less risk taking after the incident. Will it last? - only time will tell. However if it would break I would comment on this blog post and try with a higher content of glass fibre if feasible to repair. The next time I think I would have two strands in parallel to increase the amount of glass fibre in the repair. Perhaps a next project could be to see if it is possible to repair some old broken lower leading edges of my Prism Illusion (Avia Sport G-Force UL)? Yes, this repair could have some unfortunate effect on flight behavior, especially since it is far from the centre of the kite and also might affect the curvature of the leading edge. However, the Illusion spars just snapped in two pieces when they broke, so some other approach is required to repair them than the above - a thin walled carbon tube that fits nicely into the Avia spar and a very fine fibre mesh would very nice to have here. (A spin-off from this project - now I got a nice long glass fibre source for sealing the spigot of the wooden stove. No definitely not the epoxy for that - got a special heat resistant type of goo for this.)

    It's been a whiles since I added any entries to the blog but it not for lack of sewing kites. After Jester II I decided it was time for some new color chemes AND new fabric.. 22 YArds of Icarex in Black White, Silver and Gray followed soon after.. I decided to take a chance and make an offer on the scrap bin and received a good bit of the full spectrum of colors..A full sunset fade was the first endeavor followed closely by purple fade with several different shades of purple A touch of blue was commissioned by a friend and what color was left went into a true color quilt I call Scrapestry.. I PLAN for all of these kites to get first flight at the Rogallo festival at Jockeys Ridge, Nags Head NC in just over a week. Still a ways to go but Leading edges are made and the panel sewing is all done except for the center panel section of Scrapestry.. Hopefully there will be video soon..

    Finished Sails for 5 Kites from one 96' Rainbow Transition Tail today. Will finish the Endcaps, Bungees and custom Skyshark frames this week. Hopefully first flight will be at the Wright Kite Festival in 2 weeks. It's where I flew my first home made 2 years ago. These kites all have 72" LE sleeves and will use 74" LE. I'm still considering putting a vertical black stripe on the center of each sail.

    Progress has been slow. Flying from the center panel has been my main focus for the past couple of weeks. Line equalization prior to each flight is now a must. 110+ F days for the next 4 months. The next step is learning some fundamental drills. (video has been removed due to a copywrite claim on the music, here is a version with no music)
