Does being at high altitude may affect the throttle input in rise of quad?

The motor directions are correct for a KK2 and every other flight controller that I have seen. As to the props, when they turn is the leading edge higher than the trailing edge on each blade ?

Did you fix the problem noted in your other thread pointed out by johnwasser ?

   esc_1 = throttle - pid_output_pitch
   esc_2 = throttle + pid_output_pitch
   esc_3 = throttle - pid_output_pitch
   esc_4 = throttle - pid_output_pitch

In fact, why did you start a new thread at all ?
