What is the difference between a 2, 3, and 4-channel radio control helicopter?
Answers: More channel means more functions. A 2-channel RC helicopter is going to be a child's toy. It will do important up/down and forward/back movements without much athletic ability. The second channels will affix abilities such as pitch and yaw, the competence to hover, pivoting using the tail rotor, and so on. Of course, more functions means that it is harder to fly; you enjoy to actively control all those inputs only just as if you were flying a full-scale helicopter.
If you are tentative to the hobby, you should start simple to learn the rudiments of helicopter control (it is an art) and to decide if it is really for you, as an advanced helicopter can be pretty pricey compared to other RC vehicle.
The helicopter and control have switchable channel. This avoids interference with other radio controlled devices contained by the area. It wouldn't do you much moral to try to fly your helicopter on one channel when someone else near is using the same waterway. Hence, you can switch it and use a different channel.
