Is it possible to brick a set of esc's in a hard crash? If so, is it possible to get them working again? I've got one out of 3 working, but that one I replaced because the motor didn't spin freely. Thought the others were fine, but no tones from them. When I arm the only motor that spins is the one with the replaced esc.

I had a hard smack recently and now motor #4 on my ESC is done for. I get continuity between the A and C pads, motor has Fet Drag when soldered, and the motor doesn't spin when armed and just jumps when throttled up. Its possible for one ESC in a 4n1 to "Brick" or die after a crash. I was using a Diatone Mamba 20x20 40a BLH32 ESC.
