Fishman Aims For 2008 Oshkosh Display
Randall Fishman, the 2007 AirVenture
Grand Champion 'Lindy' and Ultralight Innovation award winner,
hopes to reprise his performance from last year with the
introduction of his ElectraFlyer-C, an electric-powered,
single-seat airplane at AirVenture 2008.
Fishman, president of Electric Aircraft Corp., flew his
rechargeable, battery powered weight-shift trike last year, but
this year he has upped the stakes with the same motor powering the
all-metal, low-wing ElectraFlyer-C which he expects to demonstrate
in Oshkosh this year.
As ANN reported last month,
the diminutive airplane first took to the skies under the control
of veteran glider instructor Joe Bennis. The nearly silent plane
took two-laps around the pattern without incident.
The ElectraFlyer-C is a re-engined Moni motorglider from the
1980s with an 18-hp electric motor in place of its original noisy
2-stroke engine. The Experimental Aviation Association (EAA)
reported last week the ElectraFlyer-C cruises at 70 mph, stalls at
45 mph, and has a top speed of 90 mph and a flight duration of
1-1/2 hours. The motor direct drives a 45-inch ground adjustable,
two-blade PowerFin carbon fiber propeller, which lifts the aircraft
at a climb rate of 500 to 600 fpm. Takeoff rpm is 2800. The
experimental amateur-built airplane is currently in its required
40-hour flight testing phase.
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). The cost
for a full recharge is 70 cents with the 110-volt charger. Fishman
says it's feasible to carry a small 110-volt charger as baggage on
"People will like flying the airplane because there's no
vibration and it is almost completely silent in the air," says
Fishman, adding you can listen to your iPod or use a handheld radio
without needing a helmet while in flight.
The Electric Aircraft Corp. does not sell the airplane but does
offer complete powerplant packages, including the motor and
