Hi all, I had what I have to call a double cato this morning. I put a Quest B6-0 and C6-7 into my Quest Navaho. When I pushed the button, there was a big whoop sound and the upper stage smoking and falling to the ground. On investigation, the booser motor had cato'ed (2nd one from this package of motors) causing a cato (well a spit nozzle) in the upper stage. Only minor damage to the rocket, but it was a bit of excitement.
Fly straight and true!
