Have a trex 500e, the plastic head model with the align 500mx and 70 amp align esc. It has done less than 40 flights and has not been crashed (not yet at least ).
The esc started screeching on spool up the other day and then power dropped to nothing. It seemed to have lost its esc settings so reset and it worked fine for a couple of mins then died again. Tried to spool up one more timeand esc starting smoking.
Ordered new esc but took the motor out and the pinion appears out of shape when spinning the motor. new 13t pinion ordered too.
Is it possible to bend a pinion without crashing and could this have killed the esc?
