I have built an OctoQuad Plane that seems to have potential. I have used the X type as I have not seen any real performance difference in H type. I know I need to increase my Yaw authority by introducing some induced tilt in the motors to have thrust assist but I am a little confused on the direction of which way to tilt the lower motors… I have read the “TIP” on this page https://ardupilot.org/plane/docs/quadplane-building.html indicating that in a X config the motors would tilt out from the plane 1 or 2 degrees following the natural torque of the direction of the motors. This seems to make sense to me as I can visualize what is happening but when it comes to the lower motors I guess tilting them in the same direction might actually be working against torque of the lower motors. Can anyone provide some insight on this. Should I tilt the motor pairs top and bottom with the thrust planes parallel to each other or contrasting angles with the top motors tilted out 1 or 2 degrees like it was suggested in the tip, and the bottom motor would be in 1 or 2 degrees.
