The problem isn't the modelling, but the way 3d objects are represented on a 2d surface.
Unfortunately, planes like the 109s and 190s suffer because things get disproprortionately large. take to overhead rail of the 190, or the bars on the 109.
Thew following pic shows that it's modelled correctly in the 3d model.
Unfortunately, once you do some math to get the 3d stuff done, it ends up looking a wee bit weird.
