One of my first airplanes that I keep coming back to if I want to test out some new things. Here I transformed the plane into a nice, docile tricycle Sportster that I subsequently used to test various STOL techniques.

If you don't touch the VTOL slider, or even completely delete the control surfaces on the inner wings, you have a nice generic 1950's sportsplane with a takeoff speed of 95 mph. Pull the VTOL slider back completely and with almost the complete wing at a 45° angle, it takes off and lands at 70 mph.

(And yes, this is something like the maximum lift gain I could get out of flaps, which was what I set out to find with this build.)

Use this plane as a base for your own experiments or go straight to the successors of this plane to see my experiments with STOL devices evolve into more complex and hopefully more powerful builds
