The Peris JN-1 is an American homebuilt aircraft that was designed by Jim Peris of Lancaster, Pennsylvania. When it was available the aircraft was supplied in the form of plans for amateur construction. The plans for the JN-1 were originally marketed by the designer and then after his death, by his wife, Nancy Peris. Following her death the plans became no longer available. Design and development The JN-1 was designed to be a very economical aircraft to build and fly. The prototype was constructed for US$2500 in the mid-1980s. It features a strut-braced high-wing, a single-seat, enclosed cockpit accessed via a door, fixed conventional landing gear with wheel pants and a single engine in tractor configuration. The aircraft is made from a combination of wood, foam and fiberglass. The main structure is built from sheet foam and covered in fiberglass, as are the fuselage bulkheads, the wing ribs, stabilizers, and the rudder. The fuselage longerons, wing and tail spars, the landing gear mounts, and firewall are all made from Douglas fir, with the spars solid, not laminates. The formers are made from foam, fiberglassed on both sides for strength. All fittings are made from 4130 steel. The landing gear is fabricated from an automotive leaf spring wrapped with 3-inch fiberglass and mounts wheelbarrow wheels. The wheel pants are made from foam, covered in fiberglass and then hollowed out. Its span wing has no flaps, has a wing area of and folds for ground storage or transportation. The acceptable power range is and the standard engine used is the Kawasaki 440 snowmobile powerplant. The JN-1 has a typical empty weight of and a gross weight of , giving a useful load of . With full fuel of the payload for the pilot and baggage is . The standard day, sea level, no wind, take off and landing roll with a engine is . The manufacturer estimates the construction time from the supplied plans as 800 hours. Builders have indicated that the plans are not very clear or complete and much is left up to the builder to figure out. The designer said of the aircraft: "I didn’t go for any high-tech sort of plane; this one was fun to design and build. Really a very inexpensive hobby! I guess you could spend $2,500 in a couple of years playing golf or bowling. The test flight was a couple of hours long,
