I need help and advice
I build small quad with pixhawk ( firmware 3.4.6) and ESC EMAX NANO 12A OneShot125.
First I have a problem with calibration. I do step by step ( http://ardupilot.org/copter/docs/esc-calibration.html) but after step 3 I get only yellow solid led ( the big one). I follow to next steps ( press sefty button) .
It’s seems to esc were calibrated. ( I heared meny beeps)
But after restart motor wont spin in the same time.
Motor 2 and 4 spin after arming but I have to incrase throttle about 20% to start motor 1 and 3.
Thaks in advance for any help and suggestion
