My question is, do I keep the motor-to-motor position ratio 1:1, or could this be tuned out if the vertical motors are four times the distance compared to the horizontal motor position (See the sketch for reference)?
Based on the motor rotation direction per the Ardupilot document, I think Yaw will also cause stability issues. Would it be better to have bigger props on the horizontal axis to control the Yaw effect or change the rotation direction in the diagram?
