RE: I.M.P scale
Kahn41,
Top Flite has a GS P-47 at 85"ws which I think is what you where thinking about instead of the 63" version. I think a G-45 would do there. If the Ziroli 70" comes in at 16 lbs wet I think that would be the way to go for 36cc. The only bad thing about bigger is trying to get it out of the house (hangar rash). From all I have read the P-47 is a great starting warbird with all the parts available as well as replacements. If you want to have someone cut the wood talk to Mace Gill at the AeroplaneWorks. Make sure your CG is correct or forward and use a prop of 8 or 10" pitch. Keep the tail light and don't over build thinking stronger is better than lighter. Remember epoxy is heavy.
