Well the entire 109E needs redoing, period. It's literally impossible to do some camo options because of the way the spinner is hard coded and because of the way the spine is mapped out and the sides are mirrored. (basically, you'll see a lot of 109Es with "8" instead of whatever else they'd normally have, because "8" mirrors while everything else does not).
So just ask them to put it on their "to-do list" for when they re-map the 109E. Would be much appreciated.
