What is the best way to join plastic to a body tube? I had one of the plastic fins come off my Dark Zero on it's first launch. It was attached with contact cement at the top/bottom thru the wall lugs, but the ejection charge blew out the top contact hole. causing the fin to come off ( I want to join the entire length of the fin to the body tube). I'm also now building a MAXIALPHA 3, and have read some reviews where it was recommended that instead of just attaching the fins to the upper and lower plastic rings, the fins should also be attached the full length of the fin to the body tube. Will CA glue work, or do I need to use epoxy? Also on the workbench is a U.S. Rockets "Duel 18mm Rear Eject" model, and I want to make sure the nose cones do not blow off.
