I am at a loss and have exhausted everything within my knowledge and research. I have a 250 quadcopter with Naze32 board, lumenier 12A simonk escs, fysky d4rII rx with taranis x9d plus tx. I am using betaflight to configure. I can get the motors to arm (green led lights and icon lights in betaflight) but the motors will not spin up. I've tried doing an esc calibration and I don't get beeping so I assume it's not working. I believe my min/max values are correct in Betaflight and with the Taranis, so I don't know what else to do to get these motors to spin up. Any suggestions would be greatly appreciated. Thank you.
