Warren, there is about as many ways to do it as.. well there's lots ..
I've done some of what you speak of. It sounds like its a wood project. The Buzz bomb is a pretty simple [ good first project] airframe. Since the wing is a constant chord and you want to do an electric, I wonder if a foam core wing wouldn't be a better choice? If not it would be composed of all the same ribs from one tip to the other so either way its pretty simple..
You would most likely make each of the major components an assembly, composed of parts [ribs and formers etc..] The major assemblies would most likely be the major parts that the a/c breaks down into ie; wings, fuse etc..
The wing assembly would then be made of its respective parts ei; rib's, spar cap's, sheeting, aileron etc..
The fuse would also be similar.. formers.. maybe a center crutch.. etc..
I've got several model's done of wooden aircraft and I'll post a pic or two of the model's in SW. If your just starting out w/ SW its going to be a bit frustrating for the first while as its a very in-depth program.. but take heart.. there's much that can be done w/ it..
Here's a link for a model I did about 1 yr ago..[here] its controled completely w/ manual conic algebraic equations [like 80 of them or something.. I can't remember exactly], you can change the shape of 1 controling spline and it will update the smoothing of the fuselage surface,making the section profile either parabolic, hyperbolic or a circle.. or anywhere in between.. works pretty well too.
Anyway.. feel free to post specific questions and I'll try and help where I can.
I'll post those pic's later tonight when I get home..[ the model is on my home comp.]
