H520 to h3 conversion

Replaced leg and arm there now, no led to new arm, clearly a solder issue or imu. Hopefully just a badly soldered connection.

Back to old reliable h plus to use up the stored power in the batteries

Which arm is having problems?

For me this looks like a missing power on one of the three coils. Contact or short cut in the coil or ESC. I would replace the motor or exchange with another just to see if the problem moves with the motor or not.

Confirmed led on replacement arm was faulty. So both arms still give the same fault. Next step I’m thinking is reflow solder or replace wires on mainboard linked to arm with the issue. If not working after this step a faulty imu could be next suspect

Yes replaced arm stil gives same error. If one of the 3 wires wasn’t connected correctly would the motor fail to spin at all or would it give the same symptoms I have currently where it does spin but not correctly

Another thought that crossed my mind just now is if I wanted to test a potential faulty imu, could I change the flying mode? Currently I fly with throttle on the left stick, i think it’s mode 2, if I changed to a different mode would the faulty motor still show in the same location or would it move to a different arm, provided Imu was at fault of course

Flying mode only changes which stick on the controller generates the signals. Nothing changes on the drone. You would see no difference related to ESC/motors/IMU.

A yes that makes perfect sense, thank you .
