Excuse the separate thread but the 25/05/2012 update thread is geting pretty choked up.
Can you ask Ilya if it would be possible to release another mini patch just fixing a few simple things that are having a big impact.
The Spitfires throttles go from -4 to +6lbs boost over about 30% of throttle travel and engine runs with throttle closed. Also, if fixing the throttle doesn't fix the Spitfire brakes problem, can that be done too? I think these would be fairly simple to fix, probably scaling problems. They are covered in bug reports:-
