Definitely high tech and complicated. Normal helos are speed-limited to about 160Kt because the advancing rotor blade tip goes supersonic. The X2 has to unload and slow the rotors as forward speed picks up. The winglets (if equipped) carry the lift and aft prop provides forward thrust...both of these vectors are provided by the rotor disc in a normal helo.

I think an early version was flown manually using mechanical linkages (by two pilots) but the workload would be too high for normal ops, to say nothing of combat.
