Today's sailplane is the result of constant research and studies since the beginning of manned flight (first airplanes were gliders). Pilot skill and sailplane shape combined extract the energy needed from the surrounding environment (air) for sustained flight and for propulsion.
The sailplane is quite possibly the most aero-dynamic machine ever built.

I hope the following pages will help you to understand a little more about this wonderfull sport.

PARTS OF A SAILPLANE:
A sailplane, or glider as they are also known as, is an engine-less aircraft. A sailplane has all the same control surfaces (ailerons, elevator, rudder, flaps, spoilers/airbrakes), and similar instruments to those of a conventional powered aircraft, but uses gravity as its source of power.
