The tail blade only nicked the ground it was not stopped for very long. I'll see if my LHS can help me out and see if that is what it is.

If I use an amp meter (it just shorts the circut and measures the max current) than would I be able to tell if the motor was lacking power?
I could put the motor in the circut with the amp meter and see what I get.

I'll of corse take the motors off the heli so it has no blades to hit me with.

Thanks,
Justin
