Made some changes to improve aerobatic performance, so it can now do pretty
much what i've seen p-51d's do. Be careful of spins. Added vstab incidence (real ones have it) thus improving takeoff behavior. Reduced turbo-mul to what it probably should be. Returned wing camber to Andy's estimate. Increased flap drag. And tried making adjustments to get the thing to not glide so impossibly far.
