Hey, I was just wondering if you could help me out. I just ordered a new F3 femto flight controller from emax-USA, because I had to replace a bad one. This flight controller is being used with the emax micro power pack for a flite test gremlin. I went through the whole process of flashing new firmware through betaflight on the flight controller. I got everything soldered up and I then went to the motors tab to calibrate the ESCs. I unplugged the battery and disconnect from betaflight, I then reconnected and went back to the motors tab to check motor direction. Motors 1, 2, and 4 spun up fine. Motor # 3 didn’t spin up at all. So I then went through the process of testing, motors and ESCs. I took the working motor and ESC from motor #2 and swapped it with #3. Motor #3 still didn’t work, but the motor and ESC from #3 worked fine on motor #2. Any ideas? Thank you for the help!
