Problem: aircraft like the Hurricane and Spitfire fly one wing low when flying straight at a 'combat' cruise speeds.

Improvement: Ability to manually set bendable trim tabs.

Reason: To enable players to determine settings, speed etc at which aircraft flies wings level and straight at a chosen 'combat' cruise.

Method: Simulate the fixed bending of a trim tab (or bending the trailing edge of the Spitfire Aileron) by perhaps entering a fixed trim tab offset (e.g. -2.5 degrees) in the 'Plane' settings, like we have for gun loadouts, with the resulting aileron effect calculated by the FM or even a simplistic fixed addition or subtraction of the aileron deflection.

The trim tab setting for level flight at particular air speed and power etc settings would be found by trial and error (as was the practice in RL). For example the Spitfire could be flown level at the pilots notes cruise settings with airspeed stabilised at a chosen altitude and the trim tab set to give wings level under those conditions.
