One of the most amazing things about modern radio-controlled helicopters is how fast and agile they are. Motor and battery technology has advanced sufficiently to give R/C helicopters a huge power-to-weight ratio, making possible maneuvers which seem to defy the laws of physics!
In real-time, these aircraft buzz about like giant agitated insects, and are difficult at best to follow with the camera. When slowed-down 10x as we here see in this 300fps footage, the mechanical capability of the aircraft as well as the skill of the pilot really becomes apparent.
The aircraft themselves are made of carbon fiber composite, aluminum, plastics, and other materials, and are powered by Lithium-Polymer battery packs, which can deliver massive continuous amperage (30-90 amps) at 11 - 18 Volts through an Electronic Speed Control (ESC). Power is supplied to the radio control equipment and powerful 3-phase AC motor(s) which drive the main and tail rotor.
The radio control systems typically use a 2.4GHz spread-spectrum transmission signal, and can range up to a mile (line-of-sight) or as far as you can see.
This footage was shot with a Casio Exilim EX-F1 Pro high speed video camera, at 300 frames per second. The actual frame size of 512x384 was upscaled to the 1280x720p HD frame to help preserve detail. Thanks to the helicopter pilots at the field that day who put on a great show!
