This reduces rotor hub drag since there are no ...

Location of flight controls in a helicopter. Helicopter flight controls are used to achieve and maintain controlled aerodynamic helicopter flight. [1] Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a desired way.
The Main rotor attach nut, or "Jesus nut", from a Bell 222U, shown in hand for size perspective (left) and installed with locking key (right). Jesus nut is a slang term for the main rotor retaining nut [1] or mast nut, which holds the main rotor to the mast of some helicopters.
The OH-6A helicopter (serial number 65-12917) was supplied by the U.S. Army for Hughes to develop the NOTAR technology and was the second OH-6 built by Hughes for the U.S. Army. A more heavily modified version of the prototype demonstrator first flew in March 1986 (by which time McDonnell Douglas had acquired Hughes Helicopters).
