I am building the Top Flite 65" P-47 with Century Jet retracts. Since I am an avid warbird enthusiast, I would like to make the gear doors flush with the bottom of the wing. To do this looks like some modifications are neccessary. I also would like to install a retractable tail wheel. I intend to glass and paint the finish so I am trying to give plenty of consideration to weight. Having built many slope soaring warbirds, I realize how important this is. I am at the point of framing up the lower formers and need input on the feasibility of the retractable tailwheel. The powerplant for this airframe is a YS, FZ-91. Is this wishful thinking on my part? Any feedback would be greatly appreciated.
