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.[1][2][3][4][5][6]

ElectraFlyer-C
Role Experimental electric aircraft
National origin United States
Manufacturer Electric Aircraft Corporation
Designer Randall Fishman
First flight 2008
Introduction 2008
Status Developmental prototype only
Produced 2008
Number built one
Developed from Electric Aircraft Corporation ElectraFlyer Trike and Monnett Moni

The design was only intended as a prototype and proof of concept aircraft.[6]

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 18 hp (13 kW) electric motor in tractor configuration. The sole example built is registered in the US Experimental - Amateur-built category.[1][3][6]

The aircraft is made from sheet aluminum. Its 45.6 ft (13.9 m) span wing has an area of 157 sq ft (14.6 m2). 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.[1][3][6][7]

Fishman indicated that he would sell the aircraft in April 2009, but as of February 2017 it remains owned by his company.[1][2][3]
