Regarding the update to KSP 1.2, I do not believe the aerodynamic effects are scaling when changing the size of a fin/canard/ control surface. The mass of the part scales properly and you can see the center of gravity move, but the center of lift doesn't change and there is no effect in flight no matter how big I make the part.
For some reason, fixed wings are aerodynamically scaling well along with their mass, the problem seems to apply only to moving control surfaces like fins and canards.
Other than that, I love the mod and I appreciate you updating it. I couldn't play KSP again after the 1.2 update until I could scale things again.
