".............I was wondering what kit this is your building and what is the size. Is it a tough build? ......................."

You forgot about mine... hehehe! (haven't started building yet)

Palmer, 132" w/s, plans(scratch) built. Lotsa parts, but I wouldn't guess that it's a really tough build(we'll see! )Palmer also has two other sizes, one thats a 51.75" w/s, and one thats a 87". http://www.mag-web.com/rc-modeler/palmer/product.html
