The pneumatic part looks strange

Did you notice that, when the PartScale of the wing is reduced and the wing is embedded in the fuselage part(The drug of fuselage parts has been closed). The aerodynamics of this plane will become very strange. It feels like there's a strange force acting on the fuselage. Even the wing parts originally designed for use as horizontal tails provide a flap like effect.This didn't happen in simpleplanes.
Here is an example.

So I hope I can modify the pneumatics in the game to make it more complete.
