There are two launch methods we use:
Winch Launch: is cheap and involves connecting the glider to a long cable, which is wound in quickly dragging the glider into the air. The launch height is between 1,200 ft and 1,700 ft.
Aerotow Launch: is expensive and uses a powered plane to tow the glider into the air. launch height is as much as you can pay for, but typically 2,000 ft to 5,000 ft.
