For me it looks like that the overlaid drawings in Zorin's picture just don't have the same scale. Zorin, try to scale the drawings so that the total length is the same. That should give a much better fit, perhaps the largest error may be no bigger than line thickness.

The fit is better, agreed, before it was 30cm too long now it is only 6cm too thin. Plus, the simple drawing has a line thickness of 3cm... Oh well, I think you can keep it as it is, stefan. Only for the future you should try to get hold of high quality drawings.

I think that if the visual model isn't glaringly incorrect it shouldn't be too bad. Things like the P-40s wings were horrendous, but the overall fuse length being slightly too long shouldn't be too noticable. It's better to be perfect, but better to exist than to not have the aircraft. And this looks to be pretty bloody good overall.

The key to making the game enjoyable is making sure that the flight data and performance characteristics are spot on relative to the other aircraft in the game.
If the model is perhaps not quite accurate, that wont annoy the hell out of people, if it turns out to be an uber plane, that would...

Just IMHO.
