I am building a DJI F550 with APM2.8. I have calibrated all ESC’s using the manual one by one method and all beeps seem to be fine. When I then unplug the LiPo battery to get out of ESC calibration mode and then plug it back in to begin to fly, after a few seconds one motor spins( number 6 in the HEXA X configuration) at full throttle and wont stop until I unplug the battery.
I am unable to arm the hex after this happens as well.
I took the copter outside again and this time I swapped the ESC wires 1 and 6, i.e. I swapped the motor inputs 1 and 6 going in the flight controller. This resulted in motor 6 no longer spinning when the battery is plugged in but now number 1 is. This leads me to believe that there is something wrong with the signals going to motor output number 6 on the APM2.8 itself and that the problem does not lie with the ESC’s or the motors
I hope something in there is useful. I’m not exactly sure what I’m looking for because there are a lot of .bin or .log files but most arent just that. They have extra eg. .bin.log.gpx or .bin.kmz or .bin.log.param or .rlog or .tlog etc…
