Thanks one and all!!! My faith was not misplaced!
I think the problem may be solved thanks to m102404!!!!


I'd never have figured that out with my background in kinetic engineering.
After backing the motor off, the gun runs though the gears and my son thinks I'm a hero! (Don't tell him any better..please!)
I think it was that and the battery just plain being a POS as Zone 69 suggested.
Any suggestions where I can find a better battery?
Thanks very much guys!
Now I just need to teach him to keep his eyes off the sights and on the target!
