so... I've been including a compass in my MF 220 Drachen since I made it a 2-seater, but I'm having the following problem, I have it set to a rotator but it torques the whole plane everytime the compass rotates, and it is so strong that I can't even park the plane because the compass rotates, which creates more torque, driving it crazy and it's uncontrollable... any solutions pls?
put a free-spinning rotator behind the moving one
Add another hidden needle that twists the other way. That should balance out the torques.
