Flite board folding prop running in reverse (ESC or PWM Issue?)

Hey experts

Mid ride my Fliteboard pro motor cut out. I got back on, connected, but the prop started to spin in reverse. Slowly and not in line with the motor revs. I turned the controller off and on a few times with no luck. Only after ~20 times there was a loud ‘clunk’ and then the prop was in forward like normal. (I know there is no reverse gear).

Has anyone had this issue? I’m thinking maybe the ESC or the PWM controlling the ESC? Fliteboard are not helping at this stage. Telling me it can’t happen. But I know what happened. Of course the motor is out of warranty.

Please help.

@aussieatlarge you seem to have some experience with builds and fliteboards. Are you able to help with this? Much appreciated in advance. Thank you
