A VTOL Hummingbird?
I have considered this VTOL variation of the Hummingbird configuration for some time, in response to the question: “Well, if it can hover, why not make it vertical takeoff!” In the case of Hummingbird, this would involve simply shortening the tail (increasing its area in the process) and placing a landing gear there. Voila, a personal VTOL airplane!
While feasible, the idea does have its problems. The configuration would be very unstable on the ground—a high wind might topple you over. Landing ass-backwards would be a trick; you would have to learn to use mirrors or be prepared for a big crick in your neck. And as for climbing in. . .
In short, other configurations are probably better for VTOL. Let’s just let Hummingbird takeoff and land on a runway and leave its tail alone.
