All,
One of my BALLS rockets is a CF 54mm Mongoose that is built using the epoxy that comes with the kit. There is no additional layup on the fins or fillets. It's my first rocket of this nature - all my others have been CF laminated over either G10 or plywood and followed by tip-to-tip for rockets that will see +Mach.
The rocket completely ready to fly (sans motor) with trackers, dual deploy, chutes, etc. is 1530 grams or 3.4 lbs.
My first flight will be on a CTI L265 6XL motor. I'm pretty comfortable with that flight. But for the second flight I want to use the CTI L935 Imax motor. That sims to well over Mach 2. Does anyone here have experience with a similar flight on a 54mm CF Mongoose that was built stock? I'm not looking for speculation but actual flight experience on success or failure of the same kit at Mach 2+ speeds. I've read that the epoxy that comes with the kit is extremely good but I'm wondering if the fins have actually survived those speeds without additional reinforcement. I haven't yet done a fin flutter analysis but I also wanted real-world experiences as well.
Thanks for any info you can share,
Tony
