Well, the bottom half of my Formula 200 is no more.
Yesterday was the first flight with my new EX motor hardware, and the forward end of the motor blew to smithereens. I am assuming hardware failure, since the propellant was a very well-known formula, third time I've used it. My motor mentor supervised the whole thing, and nothing was out of the usual with the mixing, casting or assembly.
The motor case was made by one vendor, and the closure, nozzle and rings by someone else. I am just chalking it up to minor incompatibility. O-rings were abundantly greased and all four were assembled.
The booster was completely scorched, and since the epoxy holding the G12 together melted, the G12 frayed. Looks like spaghetti! The G10 CRs also came apart in layers. In the center of the second-to-last picture, that's the exploded motor casing.
Enjoy the pics. She will be rebuilt! She will :fly: again!
