Here are some photos of the prototype Back Yard Flyer UL. With its unique swing-wing storage capability, this aircraft opens up a whole new option for aircraft ownership. You won't need a big hangar with this aircraft. A long trailer will suffice and save you a ton of money in hangar rent. The empty weight of the prototype WITH the Big Twin engine WITH Valley Engineering Series Three PSRU, custom carved Culver propeller, starter and alternator is approximately 240 lbs. Wing span is 25 feet. Width with the wing in its stored configuration is 83 inches. Height is 72 inches. The length of the plane with the wing in its stored configuration is also 25 feet. The plane will come equipped with a built-in ballistic chute. The Back Yard Flyer UL also comes equipped with rudder-pedal-operated individual brakes. This is a LEGAL part 103 Ultralight. WITH A DEPENDABLE ELECTRIC START FOUR-STROKE ENGINE!!
