I’m on Abu’s and Vertical’s side on this discussion. I really believe everything about a scale model scaled down from the full size dimensions can replicate the flying characteristics. True the stiffness of model will not represent the stiffness of a full size wing and aero loads will twist and distort differently from model to full size changing aerodynamics but let’s take Abu’s point here. Perfectly scale down models fly like the real thing and show the bad habits of the real thing period. Yes a servo is more accurate then a foot on the rudder bar but that’s not the point here.
