Funny i just had the same thing happen to a mamba xl esc. I tried everything, even a motor with no load if given throttle to fast loses power. I tried different batteries, i tried a receiver pack (took out red wire). different motor. Finally gave up and sent it back to castle today. weird i just read this.

Edit: I had to change the lipo cutoff or it wouldn't recognize anything other than a 2s lipo. All batteries are in good shape and work in all other vehichles.
