I offers to every member of DfA very simple model of his own plane from game, in result it will be very simple, as you can see on this sample:

All I need is screenshots of both sides of plane, from above and below, if you has more complex airframe like 410 or P38, make some extra shots from above and from below in 45 angle to clearly see all parts of your plane and of course, if you want it with wheels, make screenshots of them too. I strongly reccomend to make screenshots always with sun in back, so turn plane to proper angles in training battle to do that.
If you still had questions about it, write me!
