XNBS-3, tested August 1924, was large twin-engined bomber with steel-tube fuselage and wooden wings.
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.
Dewey Eldred’s Flyer’s Dream NX36282 was a very original prototype floatplane designed by Dewey Eldred and Sol Fingerhut.
