The flight controls pretty much snap to their maximum authority, this leads to excessive stress on the aircraft and oscillations with SAS enabled.
The control surfaces need to move more gradually, ideally this would also be tweakable by the player. In the FAR mod for KSP you can enable a feature that adjusts the maximum deflection based on the vehicles speed, like a real aircraft FCS would. Also would be a good improvement.

When control surfaces are turned on/installed on any craft that is moving through Kerbin atmosphere, above a certain speed (dependent upon craft, usually >200 m/s) when direction is changed or any input is put into the controlls with the SAS enabled, the craft starts oscillating in all directions. If this situation is left alone
