The ElectraFlyer-ULS was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's 2540NaN0 empty weight limit. The design has an empty weight of 2450NaN0.[1]
The design features a cantilever mid-wing, a single-seat under a bubble canopy, a twin boom tail, fixed tricycle landing gear and a single electric motor in pusher configuration.[1]
The aircraft is made from carbon fiber and foam composite materials. The motor and drive train are supplied by the Electric Aircraft Corporation in the US, while the airframe is built under contract by Airsport in the Czech Republic and is adapted from an existing design, the Airsport Song.[1]
The drivetrain includes a Fishman-designed 200NaN0 motor, electronic controller and 3.3 kWh LiPo battery pack. An additional 3.3 kWh battery pack is a US$5,000 option, which gives a two-hour endurance. A two-bladed fixed pitch propeller is standard equipment, but a folding carbon fiber propeller is optional.[1] [2]
