Corrections to aileron and rudder roll moment as function of AOA

[tqroljoe]

The real F-5 exhibits greatly reduced aileron effectiveness at high AOA. Conversely, rudder induced roll is greatly increased at high AOA. Little if any of this effect is noticed in the DCS flight model.

What sort of AoA numbers are you testing this at? In my experience, at higher AoA (over 20 units or so) you statement seems to accurately describe its behavior in DCS - the ailerons become ineffective and rudder is necessary to control roll.
