Heli-kiwi,
I believe you are saying that the use of 'aerodynamic' servo-flaps require less control force than if the craft had been equipped with 'conventional mechanical' flight controls. This raises a question that you may be able to comment on.
Does the use of the 'aerodynamic' servo-flaps result in a slower response to a change in the cyclic control than would be obtained from 'conventional mechanical' flight controls?
