description
Flown in a stock Aerotech Cheetah. Motor seemed under-powered during ascent and was making a kind of "ripping/rippling" noise on ascent. Rocket got to about 50'-70', seemed to lose more thrust, then the ejection charge ignited (while still under thrust). On removal motor adapter showed extreme heat damage and carbon buildup -particularly at one point about 1" above the top of the ejection nozzle.

Comments
Thrust seemed short and incomplete, with premature ejection. (stop snickering!) Note: most of the carbon has been cleaned off in the pics.
