This ultralight, weighing in at only 502 pounds can float around the world of simple planes at a measly 25 MPH. Deploy the flaps and you can land this thing at only 2% throttle. This plane is tail heavy, meaning it likes to pitch upward, allowing it to take off very quickly. You can control the pitch up behaviour with the trim. VTOL controls the flaps and activation groups 1-6 turn on lights in the cockpit... nothing else. That brings me to the next thing. A fully functional cockpit, moving controls including: roll, pitch, yaw, throttle and a moving flap lever!
