Everyone needs a hobby or an interest that they are passionate about, something to have fun with in your free time. Radio controlled vehicles are such a hobby, you can build or purchase radio controlled models of practically any vehicle you want, from tanks to cars and aeroplanes to helicopters. Radio controlled helicopters are one of the most common of these rc vehicles as they allow you the excitement of a flying model in a fairly small area.
At one time RC Helicopters were restricted to the wealthy and dedicated modellers, as they were high-priced, complicated to build and awkward to fly. In today’s hi-tech world however things have moved on. RC helicopters are now obtainable fairly cheaply and in a range of sizes and styles. You can pick up small indoor rc helicopters for below £20, which are a great introduction to the hobby.
When you first think about buying a rc helicopter you will observe that different models will have a differing number of channels i.e. 2 channel, 4 channel and 6 channel. This can be a little baffling for the first time purchaser if they do not know what difference the number of channels makes. Basically the number of channels affects the manoeuvrability of the rc helicopter.
On a simple 2 channel radio controlled helicopter you can only control the speed of the main rotor and the tail rotor, giving you simple forward directional control and up & down movement. With more sophisticated four channel models, not only can you adjust the speed of the two rotors, but also the angle of the main rotor blades, allowing for more precise steering plus both backward & forward movement.
You may possibly also observe that some remote controlled helicopters have one solitary main rotor while some others have dual rotors, which may well lead you to consider what difference this makes. Well, on a helicopter with a single rotor a lot of torque is generated by the rotor, which under normall circumstances would spin the body of the helicopter in the other direction, so to counteract this a vertically aligned tail rotor is needed. On dual rotor rc helicopters, each rotor spins in an opposite direction to the other cancelling out each others torque, so no vertically aligned tail rotor is needed. This produces a much more stable flight.
As already stated you do not need to part with a lot of money to obtain your first rc helicopter. In fact I personally feel the best type of rc helicopter to start out with is one of the 3 or 4 channel indoor rc helicopters priced between £30 to £50, as these will let you to practice flying them without worrying about crashing the helicopter on your first flights, and wasting hundreds of pounds replacing it.
Indoor rc helicopters will not only permit you to develope your flying skills, but can also be used at anytime no matter what the weather is doing outside. As you get more proficient with your radio controlled helicopter you can then upgrade to a larger more sophisticated machine.
