Introduction 1995

The Little Wing Autogyro is a series of conventional one and two place autogyros with a tractor engine layout using modern engines and produced by Little Wing Autogyros, Inc. of Mayflower, Arkansas.[1][2][3][4]

Development

Ron Herron was concerned about the problem of pushover fatalities in pusher gyrocopters. He set to develop a tractor layout gyrocopter that also met the FAA rules for ultralight aircraft. A Prototype LW-1 powered by a Continental O-200 engine was soon followed on by the LW-2. The design was influenced by Juan de la Cierva's autogyros. [5]

Andy Keech set 29 world records in an LW-5 Autogyro.[6][7][8][9][10][11][12]
