Welcome to CELIER AVIATION The original genuine home of the Xenon(s) gyroplanes Since 2006 we are the manufacturers in Poland the world's best Gyrocopter - Xenon. Gyrocopter looks like a small helicopter but the main difference is there is no engine turning the main rotor. The rotor simply self-propel (which we call "autorotate") due to the way that the air flows through them. It also does not have a tail rotor. As the engine is not connected to the rotors, this means that a Gyrocopter is not seriously affected if the engine should stop in flight. This, together with a very short landing roll (we can land in a very small open space, about the size of a putting green), means that a Gyrocopter is one of the safest methods of flying. Today, Gyrocopters are one or two- three seat aeroplanes whose maximum take-off weight does not exceed 560 kg. Modern Gyrocopters offer superb performance, comfort and above all have a safety record second to none in aviation. Flying Gyrocopters is challenging, exhilarating and brilliant fun.
