DLG or Discus launch Gliders

Discus Launch Glider (DLG) is a radio controlled model sailplane launched using a 'discus launch' in which the glider is held by a wingtip and rotated around the flyer by hand before release. Using this method of launching the average flier can achieve launch heights of greater than 140 feet (43 m), with the better throwers exceeding 200-foot (61 m) high launches.

The discus method of hand launching has now in effect replaced the older 'javelin style' launch, where a hand launched model glider would be launched over-arm, like a javelin would be thrown. The discus launch is far easier, more efficient and less physically demanding than the javelin launch.
