I was assuming the drone had been in a crash and had the motor obstructed causing a mosfet to fry. Sounds like something different. I ordered a box of MOSFETs to attempt to repair control boards instead of replacing them entirely... Ordered 50 of them a month ago, still waiting for it to clear customs. Also picked up a rework station to do the repair. Hopefully im able to salvage up some damaged mainboards and offer them up here for some savings.
