Vectored Thrust. Model lifted about 4"-6" above blast deflector and spun around on the launch rod until burn out. Delay and ejection charge was nominal. Examining the motor shows obvious erosion of nozzle on one side, some residue present in nozzle likely result of ejection charge. 180 degrees of the clay next to case shows no or very little burn residue. Case has approximately 1/3 of thickness eroded from vectored flame front.

As soon as the motor came up to full pressure it became obvious it wasn't right. Rocket rotating around Launch rod was second clue. No failure of launch rod attachment allow for a safe and amusing closest to the rod recovery after recovery deployed.
