Bought a 29mm casing and now I need something to fly it in. I've had great results from a standard Big Bertha bashed to 24mm, so I'm exploring the logistics of a BT-80 Big Bertha to fly the Aerotech 29mm reload. Any and all advice appreciated (and possibly heeded.) What's a good source for 29mmID tubing for the motor mount? Does anyone know a mail-order source for ripstop nylon for making parachutes? Since I'll be using two 14-1/4" lengths of BT-80 tube, should the rocket separate in the middle or pop the nosecone for recovery? What size chute should I use? I plan to use 1/8" plywood for fins and centering rings, with an aluminum positive motor retention ring. Thanks for the good advice!
