ElectraFlyer C “quietly wows” Oshkosh crowd
Posted By RichC on August 4, 2008
Yet another aviation post from Airventure 2008. This one unique in that the crowd was able to see but hardly here the electric-powered experimental ElectraFlyer C piloted by Joe Bennis. He made 3 passes over the main air show runway to the smile of Electric Aircraft Corporation president Randall Fishman. The specifications are pretty impressive for those filling up with aviation fuel: The 18-hp motor charges in as little as two hours at a cost of about 75 cents with a 110-volt charger. It cruises at 70 mph, stalls at 45 mph, and has a top speed of 90 mph and a flight duration of 1-1/2 to 2 hours.
According to EAA Airventure Today, “the motor direct drives a 45-inch ground adjustable, two-blade PowerFin carbon fiber propeller, which lifts the ElectraFlyer-C at a climb rate of 500 to 600 fpm. Takeoff rpm is 2800. The motor draws power from a custom-built lithium polymer battery pack; batteries are projected to have a life of 1,000 cycles. Weighing in at 78 pounds, the battery pack produces 5.6 kilowatt hours and can be recharged in as little as two hours using a 220-volt charger (or six hours with a 110-volt charger).”
