This is a simple winder for KAP. KAP generally uses strong single-string kites as lifters: you get the kite and the camera up there, and you don't do a lot with it once it's there. Meanwhile, you want to be working your controls to take photos.
This is a design that I've seen around on the internet for a while. I'm sure the resemblance to a Klingon bat'leth is entirely coincidental.
Step 1General dimensions
You'll need a piece of wood about 26" by 7". A lifting kite can put plenty of force on you, so choose something thick and strong - a floorboard or a bit of sturdy plywood is ideal. I've got MDF, because that's what was handy.
More wind = more sand. Also, it helps to sew a large patch on the bags that reads "DON'T MOVE!! These sand bags are for kite launching and landing purposes. Please don't touch them unless you've been asked to by the kite pilot"
