There are various remote controlled toys in the market, like the cars, spiders, trucks, helicopters, and many more. When it comes to RC Helicopters, for the beginner level it is recommended to start off with the Mini version. They are less expensive, long lasting and smaller in size. For the adventurous lot and who are keen to make it a hobby, the 4 Channel helicopters under 'Coaxial Helicopters' serves the purpose.
There exists 3D RC Helicopters that takes the experience to real hi-tech levels. Transmitter channel numbers establishes the factors that can be individually controlled on the aircraft. Especially for a helicopter, for flight five channels are required. Examples of control mechanisms are:
Single channel to pitch forward / backward
Single channel for throttle
Single for banking left / right and another for yaw
Single channel for up / down
The function of channels in the helicopters:
More channels mean enabling more adjustments from the remote without the need of approaching or landing the RC Helicopters. Five or more channels allow controls like adjusting fuel-air engine mixture while in the air, tune the gyro's sensitivity by using another channel. Sometimes, there is governor present that controls the RPM of the engine, switching it off and on again, presetting the RPM with yet one more channel.
A five channel remote works fine for a beginner, but since the sixth channel is very handy to tune the gyro, it is considered a default function in the simple models.
Price and channels:
People with requirements for more channels are usually more advanced players. More channels in the radios are further customized and consist of more features. Examples of the extra channels in advanced models are: number of flight models; programmable points on the curve of a throttle; and programmable mixes. The attributes also raises the price of the helicopter models severely. The more channels a flight has, the more a person ends up paying. For example, he pays less than $200 for the Futaba four channel, at the same time the nine channel helicopter costs more than $1500.
