On my last couple of flights, I noticed that the CCW motors were noticeably warmer than the CW motors. I’ve tried this indoors and outdoors. On close examination the two CCW motors aren’t vertically aligned to each other, only very slightly off, but the CW motors are. Could this be the cause, i.e. they are having to work a little harder? If so, am I safe to twist the legs a little to align them?
