I’ve had that issue once before and it ended up being my receiver... I honestly doubt it’s the motor - I would see if it’s the esc or receiver first.I spent a few hours repaing my Apprentice S 1.5 which had a broken elevator and a couple split connections between the elevator and the control surfaces. I also am working on my Radian XL 2.6 m glider which I believe has a bad motor. The ESC will work the control surfaces but not the motor. No start up beeps. when i manually move the prop there seems to be some resistance. Perhaps my imagination. I have resoldered all the connections but there is no response from the motor. I will pull the motor, once I can free the prop spacer from the prop spinner. If anyone has a suggetion, I am willing to entertain it.
Thanks in advance.
