Simulation of a free-flight rubber engine toy plane.

Using some Funkytrees magic, the moment you touch the throttle, the engine will make exactly (about)1.000 turns at full speed and then stop, leaving the plane to glide to the ground. Using some meticulous tweaking of the wing and tailplane assembly the plane can be flown hands-off or alternatively by just using trim and jaw. It does have full working control surfaces though in case you want to pick your landing spot yourself. However, the one thing you can not control is the engine. Once you switch it on, it will run at full power until it runs out of turns -for a rubber engine, quite literally.

Technical details: The plane uses a fixed propeller pitch combined with a power governor to spin at about 1.000 rotations per minute. An RPM counter, adjusted to the number of frames per second will cut the throttle at exactly (more or less) 1000 rotations. All this is done in the Variable Setters popup window. If you want to study the mechanics, this is the best place to start. If you have more questions, just ask in the comments section.

The large vertical wing area that holds up the wings serves a a a counterweight for the vertical tailplane giving the tailplane something it can rotate around rather than just rotate, making it a true rudder.

Happy landings
