If your using Dynamic Deflection, I can REALLY give some help. - - - Updated - - - Ahh, I see the problem. You have to much control authority at low pressure. Within DD, for most fighters, you would want just a little bit of authority, enough for basic maneuvers. Then, at higher pressures(40-50Kpa) you want maximum authority, cause at high velocities, an aircraft tends to keep a stable AoA.
