Discussion Motor Arm Issue (CleanFlight/Betaflight ) Multirotor Drone. But if I leave it armed and plug my usb back in the motors start spinning.
Hi,I have a diy quad using the pixhawk. I’m using the latest stable qgroundcontrol and flashed in the latest firmware. Configured as generic x quad.After arming, only motors 3 and 4 spin, an the other 2 are not, even after raising the throttle. When I physically tilt the quad to add some roll/pitch, one of motors 1 or 2 starts to spin to compensate for that. This behavior also seems to be dependent on the current yaw of the quad.I did calibrate the ESCs and also verified that motors/ESCs/power distribution is working by connecting the rc receiver straight to the ESCs.

I also tried to raise the min pwm and min idle throttle params which did not help. Raising the min idle throttle increases the speed of the 2 motors already running, but not run the other 2 motors.Sometimes, after fiddling around with the control sticks of my rc transmitter for some time, all 4 motors start to spin and I was able to fly it. But every time at the instant i arm it, only 2 motors spin and can’t take off properly.Any ideas whats wrong?ThanksEnyu.
