EDIT: IMPORTANT (BOTTOM STABILIZER WENT KAPUT AND CONTROL SURFACE NEEDS TO BE INVERTED IN ITS SETTINGS, ALSO, SET FUEL AMOUNT TO 17) The Convair XFY Pogo tail-sitter was an experiment in vertical takeoff and landing. The Pogo had delta wings and -bladed contra-rotating propellers powered by a Allison YT40-A-16 turboprop engine. It was intended to be a high-performance fighter aircraft capable of operating from small warships. Landing the XFY-1 was difficult, as the pilot had to look over his shoulder while carefully working the throttle to land. (Source Wikipedia). This plane is rather hard to fly (almost as hard as it was to build :P). Prop pitch is VTOL slider (note: negative=Insta-death). Flies pretty well, landing... well... let's just say it is as hard as the actual aircraft! Have any suggestions for fixes? Leave a comment below! (P.S. I couldn't get a 3 Blade to work well, hence 4 blades).
