Most quadcopters have motors where the propeller is situated on top and the motors pull air down and through. I am interested in building a quadcopter with the motors above the propellers. Is this simply a matter of building a frame with appropriate mounts, putting motors on inverted in the standard rotations (#1 upper right = ccw, #2 lower left =ccw,... etc.), but then putting the pusher and puller props on in reverse locations? This makes sense...unless I am missing something. Anything in the Pixhawk setup that I'd need to adjust? Thanks in advance.
