07/31/2009. Remarks by Johan Visschedijk: "Edgar J. Lesher, an Assistant Professor of Aeronautical Engineering at the University of Michigan, Ann Arbor, Michigan, USA, designed and built this two-seat pusher aircraft. Powered by an 100 hp Continental O-200 flat four-cylinder engine it was flown in 1961, after two years of construction.

The aircraft was donated to the EAA AirVenture Museum in 2000, registered as such on June 11, 2001. Presently the aircraft is on display in the atrium of the Francois-Xavier Bagnoud building on North Campus of the University of Michigan."
