Here are three of mine, which are probably way too small to be of any help. I have neither the capability (or the knowledge) to increase their size, although they may be of some use:
1) A-26 Counter-Invader (a Pat King design)
2) Stinson Model 'U' (an original design - July '89 'Model Builder')
3) Fokker T.V (original - Feb. '77 'Model Builder')
