Sam,

I think I found my problem. I put a scope meter on the power terminals on my receiver and discovered that my motor was not the one generating the spikes. It was the servos. I had bought a couple of GWS mini std servos by mistake once and thought that the slow stick would be a good place to use them. And it would have been except that when the servo motor changes directions it would send a spike back to the receiver. I could capture it on the scope. the spike would be about 2 vdc peak to peak. It would take the reciever voltage down to around 3 vdc, which I suppose was low enough to basically reset the receiver electronics and the speed controller would cut the motor due to low voltage or something. I put some old, and I mean really old servos on it after I discovered the problem and they created no such devastating spikes. I put it through several tests that I devised to try to recreate the problem with these old servos, but no resets and motor runs smoothly. I even got out my other full range receiver and put it on and all works great. I sure hope that I have solved our mysterious motor cut out problem.
