The FVA 1 Schwatze Duvel (Black Devil) was a glider produced in Germany in 1920. Ater WWI aviation in Germany was seriously curtailed with swingeing reparations and very tight regulation. One loophole in the regulations was gliding which was virtually ignored. To stimulate interest in gliding a competition was organised at the Wasserkuppe for August 1920. Professor Karman and Wolfgang Klemperer formed an aviation research group at Aachen University and proceeded to design and build gliders for research and competitions.
