The Eagle was designed to comply with amateur-built aircraft rules. It features a single main rotor, a single-seat open cockpit without a windshield, tricycle landing gear without wheel pants and a four-cylinder, liquid-cooled, four-stroke, single-ignition Subaru EA81 automotive engine in pusher configuration.
