The 2-seat Sun Flyer will be the first FAA-certified all-electric trainer aircraft. The new 4-seat will closely follow. Features of the Sun Flyer 4 include a 116 cm cabin width, 12 m wing span, ballistic parachute recovery system and a gross weight of 1200 kg with 540 kg of payload for pilot and passengers. “Like Sun Flyer 2, Sun Flyer 4 will run completely on batteries. As a result, the 4-seat airplane will have operating costs 5x lower than costs associated with similar combustion-engine aircraft. With 4 hours of flying time, the versatile Sun Flyer 4 will appeal to both flight schools and pilot-owners.”
