When Sikorsky first developed the XH-59 the engineers thought that because of the high control moment generated by the extremely stiff rotors they should reduce the amount of cyclic control available to the pilot. However, in certain flow conditions you still need the full cyclic range just to generate the minimum control moment for maintaining aircraft control. Unfortunately they learned this one the hard way by crashing the first prototype when the pilot ran out of cyclic control. Just food for thought...
