How does 3d work without variable pitch props? Reverse the motors?
yup, you nailed it on the head! You reflash the firmware on the ESC's so that mid throttle is now off, anything positive spins the motors normally, and negative reverses the thrust. So the props needs to be efficient in both directions, that's why it was screaming in inverted flight since I had normal props on
