  1. High wind is not required for this. It happened for me (see image) after two years on my B-series std and I really prefer to reach for the mid vent when the wind picks up. OK, I suppose I got some “help” cutting through the dacron from the worn bridle line - only the core of the bridle line remains there. It could have happened earlier - didn't notice it until today.
  2. The heat shrink material appears advantageous when doing a read up. Apart from the sanding issue, the strength to weight ratio should increase when the excess epoxy is squeezed out. This because of two factors. First getting rid of excess epoxy leaves a higher fraction of fibres remaining which is the major contributor of strength in the fibre/epoxy (or vinyl ester resin) matrix. Second it should allow to use more epoxy during the wetting of the carbon fibres (which are more tricky to determine if wetted than for glass fibres) which should reduce the risk of not wetting the fibres properly everywhere (we don’t want any weak spots in a load-carrying beam). Written heat shrink instruction: http://www.sollercomposites.com/MakingShafts.html The heat shrink material also appear to be advantageous for reducing the bubbles: “If you are not using shrink tubing... many people complain about bubbles when epoxy is drying” ("drying"? - rather hardens/cures I believe). Vacuum bagging seem to be the next step more expensive way of removing some more epoxy: “You can vacuum bag the shaft to achieve a slightly lighter shaft at a great expense.” From the discussion in: https://www.rocketryforum.com/threads/using-heat-shrink-tape.69266/ It appears like overheating also can lead to bubbles. Sorry if providing some obvious info above – I do part of the above read up to teach myself. As I said before my experience is limited to using electrical insulation heat shrink tubing for spar and stand off repair purposes.
  3. Much interesting project. You ( @Andy Klie ) mentioned sanding to even out the tube. Do you intend to use heat shrink tubing or perhaps heat shrink ribbon (since you are not using vacuum bagging)? In that case all or most of the sanding might be redundant. Heat shrink tubing: https://www.youtube.com/watch?v=jwExI_vnchE Heat shrink "tape"/ribbon: https://www.youtube.com/watch?v=wOZRALnsmwU I have only some experience of carbon fibre or fibre glass repair of kite spars and stand offs using heat shrink tubing for electrical insulation (because that was what I had available). I’m sure that was far from perfect, but it reduced much sanding afterwards because the resulting surface was smoother. It also squeezed out excess epoxy.
  4. One way would be to look for spare parts for the HQ Fazer XXL, since the tube diameters of that kite also are 10mm and 12mm. (and if a shop carry a special item like this (an unusual connector e.g.) it is likely a good kite shop that could be considered to be supported by thinking one time extra if you have any current or future needs for items that could be bought there in the same order). OK this is clearly not your local kite shop, but Drachenmarkt in Germany got connectors for large kites – up to 14mm. Drachenmarkt still got the large Pure kite in their logotype b.t.w. Look for “Kategorien > Baumaterial / Ersatzteile > Verbinder, Stopper”, then navigate using the images if necessary. When comparing different thread dimensions you might get some parts of the puzzle from my rookie kite making topic. There I tried to make sense of the conventions used when describing thread “thicknesses” (actually mass per length or length per mass...) of threads. Diameters of something that is soft, like treads, is hard to measure and is therefore not (I presume) used to describe threads, but is used in a (almost sensible) way to describe the needles instead. Compare measuring a needle diameter with a caliper to trying to measure the diameter of a soft thread... See the “The Thread” section in the “List of Material...” post: https://kitelife.com/forum/topic/8756-a-first-model-kite-probing-the-kite-building-ground/?do=findComment&comment=70689
  5. QLK – quad line kite And while we are at it: DLK – dual line kite OPKs – other peoples (persons?) kites
  6. This must have been towards the end of the first week+! First when seeing the video I thought: good speedy QLK flying without the unplanned landings, then later in the video you had the hovers as well. It seems like a very good progress rate there!
  7. Naaah, I’d say it is more parking the kite. If it happened to be so that it was unintentional only you would know. Funny you said so, as far as I can remember, it is the only kite that I managed to dead launch with.

    For that price consider going for some dual DLKing with this wide wind window kite. Now the over all effort is not that large. Botch-up two straight pin bar-handles(*). Allow 1-2 sessions to get used to pilot one kite. Then I’d *estimate* you’d feel reasonably confident in perhaps five sessions. For me learning to pilot two kites in a *rudimentary* way was less of a trick than learning and claiming a DLK slack line trick. This being said, this was not something I stuck to (last time was about 2 years ago), but it was a nice self confidence boosting side project. There are so many aspects and things to do in this limitless sport!! For more visual effect, attach tails to the pair of kites because you are not going to trick them anyhow (wait… is it really so that it is ”impossible” to trick a DLK through a handle?). The feeling (in the end) was a bit less relaxed than for more normal kiting with occasional ”survival mode” two second episodes. Also I’m sure that there are other kites than the Kymera that could do this, but the large wind window giving room for the two kites fits the bill. * At the time I was (perhaps too) much into the direction of wooden fibres after a broken long axe shaft incident where the wooden fibres were not parallel with the shaft. Therefore I initially put effort in making sure that the fibre direction of the handles was OK. Actually the final(?) iteration of the handles was made from a light wooden (~1.5USD if I remember it right) broomstick. After all the forces from the kites are not that big.

    Vented Kites

    Considering: Perhaps?:

    p { margin-bottom: 0.1in; line-height: 115%; }a:link { } I know what you are talking about when I pilot my happy mad calf oversteering Fazer XL in high enough wind, suddenly making one to end up three large steps downwind. It is the only kite that has made me laugh out ever.

    Though I got “a couple of kites” I can’t stop myself when I see a Thor’s Hammer (image) – I get a desire to acquire – but no, my kiting goals are currently going in another direction (and I’m now on a kite buying diet b.t.w. 🙂 ). However I’m much curious on how it is to fly, the feeling and if you manage to get any tricks out of a kite this size. A minor detail, this kite “requires” some known size structure to compare to to immediately see its size.
  12. Also, a bit late, I’d like to thank @drdante and @Louise for the related arrangements.

    I have been in a green preferring kite period but now it looks like I might enter a blue one perhaps. I really like to be helpful and specific... (You can't go wrong!)

    Out of the blue

    You see “Out of the blue” is just the beginning then it becomes “and into the black”, i.e. fully into the dark side (well occasionally DLKs then…). “You pay for this but they give you that” must quite literally correspond to your KL-subscription and the B-series you just won. The following two lines “And once you're gone, you can't come back; When you're out of the blue and into the black” is just to emphasize that there is really no way of out of QLKing. Have you figured out what I’m taking about?: Once more the tune “ƃuno⅄ lᴉǝN ʎq ʎW ʎW 'ʎǝH ʎǝH” has proven to be applicable to kiting. 🙂

    Found a video where the turtle type of “fade” was presented quite clearly and besides could be performed indoors. See at 2:20 :
