I'm making autogyros. What I actually needed to touch was the rotation speed of the rotor blades. Also the sound which I'll get to tomorrow. And I ended up adding a bool to disable the scaling down of rotor steering with throttle because things were just nosing down or up out of control and I didn't have the pitch authority to deal with it at full throttle (that was an actual code change, I don't think I could do that from another dll).
