ESC: Desync or a bad FET

Post by Cereal_Killer »

Hey guys, not a MW issue specifically but I'd rather post here than RCG...

Is this a bad FET or a simple (or maybe not-so-simple) desync issue happening in this video? It will run for the full battery at <50% power, the jitter / "miss" happens only above ~60-70% and it's nearly constant however this is as bad as it gets. Other videos I've watched of desyncing ECS's seem absolutely horrible with the motor coming to a full stop and sounding crazy.

Note I had one FET that appeared physically damaged so I replaced it (with a tested working, matched FET of a MCU-fried identical ESC I had in the bin) which is why I'm not sure what the problem could be, I guess there could be another bad FET but I'm just not sure, replacing the one FET made no difference, but again I replaced that one cause it appeared physically damaged, I'm sure there could be another bad FET that's not visible damaged at all.
