Guys,
Static of sufficient energy to kill FETs would have been causing problems everywhere else, too. These FETs have internal protection to prevent damage (zener diodes) and are part of a circuit board where 12 FETs live. For only one quadrent to die from static is unlikely. It is still a big puzzlement though. For only one quadrant to fail (Not two opposite quads) then there had to be something wired incorrectly in the external circuitry. Something like one of the battery leads going to the motor and the other going through the controller. This could put full battery voltage across one quad set but not destroy anything else. It seems so unlikely though since the wiring error that would cause this would be easily diagnosed. It could happen, just not high on my list of possibles. It may remain a mystery for the rest of eternity.
