I shot the wing tip off one of those F4U-4 perkie rides...
This guy goes into a dive and just walks away from my P51.
I get the impression that loosing parts in this game doesn't affects the aerodynamics at all.
It may affect the ability to pitch, yaw, and roll, but lift and speed performance doesn't seem to be affected.
I wonder if multiple .50 cal bulwet holes in the wing affect lift.
