Tilt rotors vs. helicopters-- manueverability in VT mode.

Lightly loaded, either can do a full range of hover maneuvers. Forward,
backward, sideward, up and down. Heavy, not necessarily so. But then,
the
same is true of conventional helicopters. . . .

Just a question-- how does the X-15 or the V-22 compare to a real
helicopter when hovering? Can they do helicopter style manuvers, or
are we talking more just up and over on the way to horizontal flight?

The tiltrotors have not optimal rotors for hovering and not optimal props
for crusing, Therefore they are les effective in hovering than conventional
helicopters and slower than conventional turboprops in cruising. The only
way, to fly fast with a helicopter is to stowe the rotor blades after the
vertical take off and convert so the helcopter into a fixed wing airplane.
