If I deactivate the Bf 109 cockpit mod I can't fly Bf 109E's: can't see the cockpit and can't control the plane.

Same thing here. This is real a problem for those of us who don't have enough VRAM for the (wastfully large) textures in the Bf-109 cockpit mod.

Edit:
nm, I figured it out (you have to disable the bf-109e mirror mod)
