There are a few topics about putting LEDs on your kites but to my knowledge none about putting reflexes on the kites. This is not anything I've tested (when I no longer can see a kite it has been time to go home), so I can only share ideas (for what they are worth) and listen to others suggestions/experiences.
When I saw this kite being offered, Hot Stripe XL Reflex (3.4m) by Space Kites I started to think about the matter. If you don't happen to have a kite that got band/ribbon of reflex material already sewed into every seam you would need to attach some reflexes yourself. To see the reflexes you would need a light source close to your eyes - a headlamp with a not too focused light cone would be the option I suppose. If the light cone is too narrow and is not adjustable, perhaps a transparent but frosted piece of tape could do that? Why? - To diffuse the light so that the demands on head angle to kite gets relaxed.
So what to use for reflexes then? Reflex stickers would be quick and not demand any sewing/holes to be put in the sail. Of course you wouldn't like to leave any glue residues from reflex stickers or tape on the sail. Therefore I'd suggest the special tape type for construction sites when taping polyethene/polyethylene films. This tape has to my experience not left any residues. The sticky adhesive has never aged and never hardened even though the patch was sitting on the wall for more than a year. I have reused (for non-kiting purposes) these tape patches for several years. On the data sheet of one of these tapes it states that it should be UV resistant for three months. On the negative side of this tape (figuratively speaking) is that it is somewhat less sticky than ordinary tapes - when I've tried to protect the LE with it it didn't last for so long time. I think that it has to do with another limitation of this tape - when going around small radius convex surfaces one side of the tape would lose contact with the surface and start to peel off.
The way I imagine using it, is to use the special tape to hold thin stickers attached to the sail by covering the sticker by a larger patch of tape. Obviously you would need to use the transparent version of the tape. The glue of the sticker needs to be destroyed or covered - we don't want stains remaining on the sail. These combined sticker/patches could be transferred between the kites and be stored attached to a somewhat stiff sheet of plastic or perhaps a piece of card board covered/wound with cheap packaging tape.
Some bonuses would be that there is only one lamp's batteries to keep track of - the one attaches to your forehead. Having a good headlamp should also make it easier to disassemble and pack the kite and gear in the darkness afterwards.
Another characteristics would be that the reflexes are more stealthy than LEDs in that you need to direct light origination from an observer for them to be visible. On the other hand if a powerful light source, such as the head lights of a car would be used, they would be very visible from that car. More advantages would be that light is reflected from a large area and that the reflexes can be rather bright all over the surface. I'm not realising the reflex stuff now, after all, the days are getting longer in the northern hemisphere and the nights here are going really short soon. This is more handing over my current thoughts in case it would be of use for anyone.
Now if I only could be more persuasive so that my children also wore the reflexes to a higher degree to be more visible in traffic and darkness. To defuse the argument "but you are not doing it!" I wear them more than necessary.
I got permission from Space Kites to use the kite images there here by e-mailing them. The method I used was to use the e-mail address they give in their web page (and wait), while I haven't had any luck with the contact form (of course I can't 100% exclude the possibility that it could have been my spam filter, but I don't think so).
Hey guys! Me again! I'm here on behalf of a Mechanical Engineering Project that requires a mechanism to be built that will launch a kite in low winds so that it will be shot up to 50m where the better winds are. I'm back with another few questions to ask all of you. Any help is appreciated!
1. How do you normally launch your kites? Besides tugging and running backwards?
2. Were there any methods that didn't work? Why?
3. At what speed do you consider low winds? How fast must the wind be to lift a kite?
4. What's the weight of your kite along with the photography rigging?
5. What types of kite do you use? What are their specs? What winds do they fly in? How heavy can the lift?
6. What type of cameras do you use?
7. What has been the smallest and largest kites/payloads you have used?
8. Do you KAP on land or at sea? Which do you prefer?
9. How much would a full set be? Kite and rigging included?
10. Have you ever used methods that involved an energy source? Batteries etc.
11. Do you fly on your own or with a group?
