Schweizer SGS 1-36 Sprite SGS 1-36 Sprite experimental prototype, registered N502NA, was acquired by NASA's Dryden Flight Research Center at Edwards, California and used for research into controlled, deep-stall conditions at an angle of attack of more than 30 degrees. The Sprite was used for the test program because of its slow speed and the simple aerodynamics of its long unswept wing. Schweizer Aircraft modified the Sprite's horizontal stabilizer to allow it to produce an elevator angle of up to 70 degrees. NASA also modified the Sprite to permit better pilot entry and exit. Radio-controlled-model, ground tests and simulator tests were conducted before manned
