I have a FSESC 4.12, and a Bafang 8fun geared hub motor, and when i do the motor configuration and control it with my keyboard it oscillate at the end of the RPM, and when i change the KP of the controller it stop doing that(there is always a some vibration). But when i set the app and throttle config, the control whit the keyboard it ll make noise(ti,ta, tac) without rotating.
I have a video this may explain more.
the motor is working flawlessly with the original controller.
