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.
