So I have flown this copter 20 times, didnt change anything apart from the SD card to try and avoid it failing to boot up for SD card problems. So I fly it last week, bring it in to change batteries, go to take off again and the motors won’t spin up on arm. I bring it in, re-calibrate the ESC’s because that fixed it once before.
Re-install the firmware and start again, nothing. Same thing every time with the exception that it sometimes will arm the first time I try on new firmware, but not again.
Tried new transmitter, nothing.
Tried new ESCs and motors. Nothing
3DR tech support keeps telling me that it is a setting problem, but please watch this video to see that I follow the correct procedure for binding the radio and calibrating the radio and ESC’s and it will “arm” but the motors will not spin for any throttle position.
I am 99% sure that the board is bad, but I would be more happy if someone could tell me what I did wrong.
Thanks for the help
