RE: Retracts for a 40 size p-47
ARF's have gotten darned good, simulators have gotten amazingly good and there are now two generations of kids who grew up with joysticks and electronic controlers. BUT . . . retracts don't have much "play" and a bouncy landing can be expensive. A P-47 WILL bite you if you try and land too slow. Try and slap it down and the retract servos become wing spoilers - if the gear doesn't fold up or tear off first.
Not knowing the particulars I can't say if any pilot I haven't seen fly is ready for retracts and a low-wing warbird, but if you're not then be warned that the School of Hard Knocks gets very steep tuition and will be tough on any "working man's budget".
