Motor Gliding

Motor gliding is a form of powered gliding where a small engine, usually a single or two cylinder, is used to power a glider for increased speed and range. The motor often has a fold able prop used to provide thrust during take-off and while in-flight. Unlike traditional powered aircraft, motor gliders use the engine only when it is necessary to gain altitude or increase range. When the engine is not in use, the aircraft is gliding, using only the momentum from thermals or ridge lift. Thus, motor gliders are highly efficient and can stay in the air for hours at a time.
