6Ch Single Blade
The controls on a 6 channel RC helicopter are actually the same as a 4ch, the extra 2 channels are controlled automatically by the helicopter. When you apply throttle not only does the speed of the rotor blades increase like on a 4ch, but also the blades angle upwards to create much more lift. There is also a switch on the transmitter to angle the blades downwards to create down force, this allows the helicopter to fly upside down. The extra lift and ability to fly upside down means that a skilled pilot can perform advanced tricks and impossible maneuvers. 6ch helicopters can also be used in windier conditions as they have more power to counter any wind.
