The Easy Riser was developed by
Larry Mauro from the earlier
Kiceniuk Icarus II biplane hang glider. An engine was installed by
John Moody in 1975 so the glider could be launched from flat terrain. Early powered versions consisted simply of a motor added to the foot-launched hang glider version with control by a combination of weight shift for pitch and tip rudders for roll and yaw, with the tip rudders used together as
air brakes. Because many pilots could not run fast enough to achieve take-off, wheeled
tricycle gear was added. The aircraft exhibited poor pitch stability, so a
horizontal stabilizer and
elevator were added. Finally, on later versions, the tip rudders were replaced with a tail-mounted rudder. ==Aircraft on Display==
