This is pure hypothesizing on my part, but it seems to me the X3 arrangement woiuld be a bit "mushy" in hover. With the props that close to the main rotor hub, they don't have nearly as much of an arm as a normal tail rotor. If they are, say, half as far from the center of rotation as a tail rotor, they produce half a much torque for same thrust level... meaning they have to produce twice as much thrust to counter the same level of torque. Which may well be easy... but fine control would seem to become much more difficult. So a conventional helicopter might remain rock-solid in a hover in breezy conditions, but the X3 would seem more likely to wobble arund a bit.Retrofit said:How a co-axial rotor (X2) or a tilt-rotor (Bell-Boeing V-22) behave vs a single rotor + tail rotor or, in the X3 case, a single rotor + lateral differiential propellers?
Of course, it could be that control is good enough so that this difference is hardly noticable.
