We had everything to gain and nothing to lose on the ESC on which I changed the caps. Two of the caps were bent, and two also had one lead each pulled out of the can, so the ESC was unusable as it was. If I had failed, we were no worse off except for the expense of 3 $.85 caps.
The case was also broken, so we used clear heat shrink on it, and cut out a hole where the label and heat sink plate is. The thing looks like it has a condom on it!!
I got the parts from DigiKey for about $0.60 each and they seem to be working fine. I tested it on the bench with a Pletty EVO and ran it from 500 to 6200 rpm smooth as silk. At less than 500 rpm there was a high frequency screech that might be due to the 32kHz PWM frequency but we don't need to run it below 500.
