In 2008 was the debut of the ElectraFlyer-C at the Experimental Aircraft Association AirVenture in Oshkosh. This all-electric, single passenger aircraft, fitted with a custom-built lithium polymer battery pack was able to cruise at 70 mile/h for 1–1/2 to 2 h and charged in as little as 2 hours.
The ElectraFlyer-C was designed and built as a prototype and proof of concept for economical electric flight.
