RE: Pratt & Whitney 1/5 scale radial engine for warbirds
Believe it or not, some of the less expensive airplanes fly quite well but don't look so hot as for scale fidelity! I am building an exact scale F8F-2 Bearcat for the final home of the R9 that I am testing. I really don't want to do alot of mods on the scale airplane. I would rather do that on a lesser airplane. When first setting up a new engine, fuel system and ignition system, it is better to risk a less expensive airplane to the possibility of dead stick landings, etc.
