uuuuurrrrrggghhh?
Not too sure about that. Fly them daily and haven't encountered this technique yet!
Nobody has mentioned the DASH yet which is fixed into the cyclic pitch control run. It fools you into thinking that the controls move EXACTLY like a 'normal'chopper, whereas the fact that the two heads go translational at slightly different times would otherwise give an odd feel. It just does this by expanding and contracting within the control run, all controlled by the AFCS (Auto Flight Control System)
Awesome helicopter, and great when people are shooting at you!!!!!
