To launch the basic plane on the left, throw it in a small angle upward. It will glide a very long distance and it will loop 3 to 4 times in the process.

If you make 2 fins on the wings, the launch will be even more spectacular. It will make a 360 degree flight and return back to the launching position. If you throw it in an angle upward, it will make a 360 degree somersault and it will return to the original position. With a bit of practice, you can catch it every time after your launch.
