Thanks for the advise and help I think I do need some experience and more knowledge about design but I don,t realy want any other plane and have already comitted to working out numbers and figures to make it an advanced sport trainer I can not find any kits or plans for this plane anywhere not at 91 2 stroke engine anyway. I was going to make it 71" or so but I think I will research a bit more. I have a pretty good idea of how to build a good strong and lite wing and fuse but where the wing bolts on I think I could do with some more info on different methods basicly would it be sound to bolt it onto hard balsa sides with the blind nuts secured into ply.
