Park flyer
From Wikipedia, the free encyclopedia
The term park flyer denotes a class of small, primarily electric powered radio controlled aircraft, so named because their size enables some of them to be operated within the confines of a large public park. Some are slow and docile enough to fly within an enclosed area such as a gymnasium or even a living room[1]; while others require the open space needed for larger models due to size and/or speed.
Because of their size and relative ease of setup, ready-to-fly park flyers are among the most popular class of RC aircraft for beginners and advanced pilots alike. Advanced electronic and material technologies have even brought forth high-performance, park flyer sized "3D-flyers", or fully-aerobatic aircraft capable of extreme high g maneuvers and even nose-up hovering. Once the exclusive realm of giant scale, 3D flight is now possible both indoors and out with certain park flyer aircraft.
Park flyers have created an inexpensive and convenient way for beginners to get involved in the hobby of RC flight. The modern materials used in the simple construction of these aircraft make field repairs possible even after significant crash damage. Their small size and quiet operation make it possible to fly them in residential areas.
The trade-off is that a model with low flying speed is more susceptible to wind and turbulence. Some park flyers cannot be flown in anything more than a light breeze: typically a wind speed of > 50% of the flying speed is the limit (although experienced pilots may enjoy flying with a negative groundspeed).
A note on safety: some 'park flyers' (especially small delta-wings) can fly at an appreciable speed. These can cause injury to passers-by in an accident. Pilots should consider what might happen if they lose control or have radio failure and fly into a person/dog/car/building; therefore keep at an appropriate distance.
