Pixhawk 4 ESCs on arming


I have wired up my Pixhawk 4 with carrier board as per the Airframe Reference guide for a Hexarotor X. Upon starting up the drone and arming it motors 3, 5 & 1 fire but 2, 4 & 6 do not, when I increase the throttle these extra motors start up.

Is this normal behaviour? If anything I would expect opposite motors to start up.

Here is a video to show what I mean https://youtu.be/c_93IRYNZDw

Thank you

Have you tried ESC calibration?


If the ESC calibration does not help, try to increase the “idle throttle” in the “Tuning” menu or increase the “PWM_Min” Parameter in the “Parameters” section.
