Awarded to the Club Champion (six best flights) in memory of Paul Tingskou who was one of the Winnipeg Gliding Club's most able and enthusiastic founding members. The Eppler airfoil was created by Dr. Eppler for an advanced high performance flying wing sailplane which Paul designed over a period of years, and was about to begin to build at the time of his death in 1976.

In previous years the trophy was awarded on the basis of a pilot's best five flights.  From 2003 to 2010, the pilot's best six flights in Manitoba were used in accordance with the CDNC OLC Classic contest rules.  Starting in 2011, the pilot's best six flights in Manitoba have been used in accordance with CDNC OLC Plus contest rules.
