Electric Aircraft Corporation ElectraFlyer-C
The Electric Aircraft Corporation ElectraFlyer-C is an American experimental electric aircraft that was designed by Randall Fishman and produced by his company Electric Aircraft Corporation in 2008. The aircraft is a converted Monnett Moni motor glider intended to test electric propulsion technology for the future Electric Aircraft Corporation ElectraFlyer-X.〔Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 45.

==Design and development==
The aircraft features a cantilever low-wing, a single-seat enclosed cockpit with a bubble canopy, fixed conventional landing gear and a single electric motor in tractor configuration. The sole example built is registered in the US Experimental - Amateur-built category.〔〔
The aircraft is made from sheet aluminum. Its span wing has an area of . The motor is an ElectraFlyer direct drive propulsion kit motor, powered by a custom-made 5.6 kwh lithium-ion polymer battery pack. The batteries are mounted in custom-made, ceramic-stainless steel firewall boxes, sized to fit the space available in the fuselage. The motor returns an 88% efficiency, with the motor controller consuming 2% of the power. The batteries fitted give an endurance of 1.5 hours and take six hours to recharge at a cost of 70 cents for the power consumed. While descending the propeller generates power to recharge the batteries. The ElectraFlyer-C received its airworthiness certificate on 11 April 2008.〔〔
Fishman indicated that he would sell the aircraft in April 2009, but as of June 2012 it remains owned by his company.〔〔〔
