Helicopter design pioneers like Arthur Young presented and Stanley Hiller long ago that helicopters would be widely used as vehicles for personal transportation in the future. However, small and simple private aircraft gained more importance then helicopters, because not only economic but also necessary for the maintenance costs were low. A small airplane propeller is much more popular than a small helicopter with complicated control mechanisms. Helicopters are notonly high maintenance costs, but higher insurance costs as well.
Stanley Hiller, the biggest advocate of personal helicopters, built a prototype private helicopter with coaxial rotors, and also developed a conventional helicopter, the helicopter costs for individual citizens to reduce. Another aviation pioneer, Frank Robinson developed the most personal helicopter, the Robinson R22. The R22 has a simple design with a pod-like cabin and tail boom assembly of a conventionalAnti-torque propeller and runs on a 124-hp Lycoming O-320 engine that drives the two rotors with two blades. Although the R22 has a higher average accident rate, nor has been authorized by the Federal Aviation Administration as safe. It 'is generally used for light utility work such as cattle breeding lines, traffic monitoring, agricultural spraying and police observation. However, the R44, the upgraded version of the R22, a larger engine and is much more reliable than the basicModel.
Just like private aircraft, some helicopters can also be built from kits, in which a person can buy the kit and then assemble the parts themselves, that the cost of the helicopter significantly. The most popular amateur built helicopter is sold in the U.S. until now, the B-8 Gyrocopter Bensen. Some of the other trendy helicopters commonly built by an American Sportscopter first ultralight helicopter 254 Ultra Sport Kit, The Rotorway Scorpion133 and Dragon Fly333
Although there are many small helicopters built by various manufacturers in the United States, the helicopters could not, with less light fixed-wing aircraft flying not only easier but cheaper to maintain in order to compete.
