The most popular way of obtaining a gyrocopter is by building it from a gyrocopter kit. The gyrocopter kits are sold between $7,000 - $8,000 and $25,000 - $30,000 - at least those that I have seen (You can find some kits here). Before buying an autogyro kit ask the seller if their kits are certified and who uses them. The Barnett Gyroplane is a single-place craft constructed of tubular 4130 steel, fiberglass and aluminum. Its pusher prop is powered by a 65-hp Continental engine (originally a VW engine). The pilot sits inside an enclosed cabin shell. JERRIE BARNETT dies in his sleep on August 4, 2009. Jerrie was one of the gyroplane pioneers with his safe, sleek, aircraft engine powered, one and two place gyroplanes. He was a good friend and he believed in helping others. He had recently purchased the rights to manufacture Rotordyne blades in the hope of providing rotors blades for his kits.

The Barnett J4B is a small gyroplane marketed in the United States by Barnett Rotorcraft for homebuilding. Originally flown as the J-3M with an open cockpit and fabric-covered sides, later versions have a fiberglass cockpit pod either partially or fully enclosing the pilot. Apart from the basic J4B, versions available in 2007 included the BRC540 (two seats side-by-side) and J4B2 (two seats in tandem). A J4B2 piloted by Ron Merkle holds a coast-to-coast speed record in the United States for gyrocopters.
