plywood

Hello! This is a thread on my attempt in repairing fin damage to my rocket. Recently I flew a successful L2 attempt at Tripoli Houston on a AT J270W to around 3300 ft. Due the fact that I launched at Hearne, my rocket decided to land on the runway with the picture being the damage to one for...

I have a Loc ultimate buzz rocket which has 1/4 inch ply split fins, that are unglassed. I have been looking for information on split fin flutter, but can't find any. Will the fins be able to survive going mach 1.1? It would be on an l2200.

While you can expect a wide variation in the strength of different types of plywood, when it comes to low and slow M power builds are the bulkhead generally fabricated from ¾” or 1” thick ply? Something else?

I see some sellers out there do clones of OOP kits or kit parts. Does anybody know of a business that sells plywood fin duplicates of the Estes Executioner kit?
