Hello all, I need some advice on fin attachement on min dia airframes. I am constructing a 54mm min dia rocket that will have surfave mounted 0.140 carbon fins on a phenolic tube with a carbon sleeve. The root is 5 inches and the fins were attached and filleted with JB weld. I have read that the Performances's mongeese (?) have surface mounted 1/8" fins that suvive mach+ flights when attached with the only provided adhesive. My question is should I add another fillet layer with chopped carbon fiber or tip to tip fiberglass or both? Ultimately, I would like to see this bird fly on a full K or smaller L but test flights will be on an H or I and then a J 350 that sims approaching mach 1.
Any advice is appreciated.
Thanks
Craig
