....Models fly in the same air, so do not 'influence' the same mass of air to do the job, and have much lower inertias than full size, so need much less 'bank angle' to turn at the same rate, etc, etc, etc.
Actually if you follow the 'rules' in the article i linked to in post #2 you will end up with a plane that flies in a perfectly scale way in regard to bank angles, turn radius, climb angle, take off distance,etc etc.... However the model will appear to fly faster than the linear scale would dictate because, as the article describes, you would need toallow for'scale time'.. that is time for a scale model runs faster than full scale, by the square root of the scale factor.
