Haha, that's a smart way to do it. I've doing a similar thing when making shockies but my "proper" model experience extends only a funfly:




Your method defines the plane in which you wish to draw your former for example, but can you use the shell to determine the "outline"? One last thing for now, though I find your work is of excellent quality and well thought out so no doubt I will be back for more, the curved fuselage sides are determined through what method? As I cannot see how the shell can play a role here?

This is all helping me to get my 120mm EDF project finished, I've got a solid fuse just need to model the wings/empennages!
