Regarding the issues with the FPV on the Bi-copter… Please correct me if I’m wrong!

Reason why the MV22 Osprey doesn’t have an issue like this in real life is because of how slow the action of changing the tilt angle is. This and the mass of the aircraft dampens out any oscillations from tilt change.

Having a think about the Bi-copter, with the little weight it has and the speed of the tilt change from the servos it’s bound to induce some oscillations. The friction of the gearbox inside the servos is probably whats causing it to pitch down when the rotors tilt forward.
My immediate thought is adding mass to the whole drone and centring the CofG to be inline with the two rotors. But with such high speeds of tilt change it won’t be worth it (and who wants a heavy drone!?).

It may require a third small rotor at the aft of the drone hiding near the body which powers up to keep the drone level when the rotors are tilted, but that would be taking away from the ‘BI’copter feel, basically a tri-copter.

Any thoughts on this welcome.
