I don't want to be picky, but you should have used the racks from the G-2 and not E-7.

Look here

The way it is now is also problematic as the skin file overpaints the rack, which can look sort of strange, depending on the skin.

Rack is coded in G2 lods. To import it you have to import also G2 fuselage, and it's a nonsense. You'll have another Gustav, may be a G4 but not a Friedrich.
All racks in game seem to be coded in the aircraft lods.
So you can't add for ex. bomb or fuel tanks to Mark.Vc, if you don't import lods from Mark.VIII or Seafire. These aircraft have rack coded in their lods, Mark.Vc doesn't. But at least they have the same cockpit shape. F4 and G2 don't have it.

So, you can only hope in AAA team with 3D converter.

That appears to be rather strange, as the rack for all the Gs and Ks is the one that has its own skinfile and therefor shouldn't be part of a plane model. It appears together with the loadout when selected, unlike the one that you have chosen, which is always part of the plane (uses the plane skinfile) and only has the loadout appear instead of rack and loadout.
