Andy Reynolds' Vought XF5U
The XF5U was an experimental design by Vought during World War II. The flat, round-shaped body led to the nickname “Flying Flapjack.” The entire body is the lifting surface, and its design resulted in low takeoff and landing speeds, but a high top speed.
After some “interesting” prototypes, the final version of the XF5U flies well. It’s fairly quick and maneuverable, yet can slow down nicely. I set the elevons for as much throw as I could manage. This isn’t really needed for normal flying, but it does allow for some tight maneuvering.
One of my favorite moves is to pull vertical, and apply full throttle and full aileron at the same time. The XF5U keeps going up for as long as I like, rolling all the way. Land it under power; it doesn’t have much of a glide, but will settle to the ground nicely with a touch of throttle.
