How do ultralight gliders acually fly?

There are two major types of glider flying - the firts is when your glider is drawn from a powered airplane. At some time the rope connecting both aircraft gets released and the glider can start it's engine less fly.

The other method is through winch and tower. The glider is connected to the winch throught a rope. The winch starts rotating thus pulling the glider. Once the glider gains enough attitude the rope can be released.

One ultralight glider can fly for many hours without engine and can raise quite a good speed.
