The Sunseeker Duo is a twin seat all-electric solar-recharged powered aircraft.
Designed by Eric Scott Raymond, the plane can take off and achieve enough height for the motor to be switched off and follow thermals like a glider (sailplane), allowing the batteries to be recharged through the solar cells on the wings.
The Sunseeker Duo is a high aspect ratio side-by-side seat composite construction high-wing aircraft with a T-tail arrangement with a single electric motor mounted in the tailfin (vertical stabilizer) driving a forward mounted propeller.
1510 solar cells capable of generating up to 5 kilowatts power the motor and battery pack.
