I was wondering if there has been any attempt at building one fixed hub helicopter with twistable blades hosting at 75% span one electric servo motor actuating trailing edge flap, where cyclic and collective pitch adjustment is programmed in flight computer, instead of having a mechanical synchronization & actuation.
This could allow one simple rotor hub and rotor axis design, only including brushes or brushless things to transmit electrical needs to servo motors.
Mainly getting rid of this:
and using fly-by-wire? If not why?
