My Concept flies inverted with 4.5 deg of neg pitch in hover, up to 9 at forward flight inverted.
But basically I agree with NickP and MoneyShot. The model rotor is doing about 1800 RPM and while the coning angle is less comparatively, the room between the rotor and boom is greater (comparatively).
When discussing inverted forward flight, or even an inverted hover for full scale, I also tend to wonder "Why?"
No practical use for either maneuver, certainly would be hard to maintain references while hanging upside down.
Or maybe just as a last ditch combat tactic? To quesinart your opponant with the mains ?
