Hi community, What could be the reason for a quadcopter, CW motors always spin harder than CCW motor during a position flight? A recent build of my drone shows the CW motors get very hot after 2 min flight, much hotter than CCW motors. After review the flight log: https://review.px4.io/plot_app?lo…

Hi @cjffly , This is due to a misalignment of the rotors; the drone is basically always fighting against a yaw torque. Instead of trying to align them perfectly, a better approach is to tilt them in the direction where increasing the motor RPM will not only create yaw torque by the propeller drag …

Thanks @bresch , will test this and update the result!

Hi @cjffly,

I also find this for my drone. Do you have any update about new tests?
