I'm working on an Estes Vapor. I want to put streamer recovery in it. The streamer is 20'-0" long but fits into the BT60 easily. In fact too easily. Even though I wrap like 3 feet of Kevlar string around it as soon as I put it in the body tube it unravels and ends up wrapping on the shock cord. One thought I had was a small piece of body tube that the rolled up streamer fits into nicely. On one end of this body tube I would put a small parachute. The idea is that upon the nose cone with the streamer attached will pop out and the small parachute will pull the body tube away off the streamer allowing it to unroll. Maybe there is a special way to tie the string around the streamer in such a way it will hold it until the shock and wind of deployment will pull it loose? Any other ideas? I'm sure someone has thought of something.
