"Brother Dixson says his experience testing Sikorsky aircraft.....RBS causes the aircraft to roll in the same direction as the blades rotate. American....left, French/Russian....right.
negative ghostrider - brother Dixson says that an aft cyclic demand will cause a roll right appropriate to the rate of aft cyclic demand. That is not the same as a rotor reacting to RBS where the pitch nose up is an aerodynamic reaction not a cyclic demand.
John - what is confusing is that you start talking about S-55 which will be an anti-clockwise rotation with stall giving a roll left and then talk about a clockwise rotation regarding the aft cyclic demand - is that a typo?
