Check out the claims for this wooden Spitfire! I want one, but my wife won't let me!

Quote from the site:
"The use of both classic construction methods and the wood sandwich skins result in an aircraft that is a ton lighter than the original Spitfire Mk, IX, yet is stressed to 10G ultimate load. At 2,000 pounds lighter with the 1200 horsepower Allison V-12, the SAC Spitfire will easily outperform any original MkIX. Acceleration and rate of climb, will be nothing short of breath taking. Turning performance, maneuverability, low speed handling, and balanced field length will be noticeably better than an original metal Spitfire."
