It is important to know how many channels the RC helicopter you are purchasing has as the more channels a RC helicopter has the more flight capabilities are available to the pilot. I was a bit confused by this when I was fist in the market for an radio controlled helicopter. The 2 Channel RC helicopter has very limited motions. It will allow you to move up and down and to spin in different directions.
Spinning in the air is much like spinning a bottle on the ground. Spinning only allows you to change the direction you are facing or going. Additionally the 2 channel RC helicopter does not allow you to control the speed of your forward motion and does not allow you to go backwards. Because of the limited mobility, precise landing becomes a little more difficult but is not impossible. The 3 channel RC helicopter has a little more control than the 2 channel. The 3 channel will allow you to go up and down, forwards and backwards and spin left or right.
Because of the additional control you can make the helicopter over precise landings are much easier. The major difference is having the control to move forwards and backwards and it makes flying a lot more fun.

On 6CH radio controlled helicopters and full-scale helis for that matter , the main blades can change their pitch angle.
What this means is that if you sit the heli on a table and look at the tip of one of the main blades, the chordline of the blade can be tilted through a range of angles by the servos. In this sense, the rotor disk of a heli is a bit like a variable-pitch prop on an airplane.
If the heli is hovering and you wish to make it climb straight up, you increase the pitch of the main blades, and increase the throttle so that the engine can overcome the increased drag and keep the blades turning at the same speed. The increased blade pitch results in more lift, and so the heli climbs. At high throttle the engine puts out more power, but there is a corresponding increase in the load on the engine due to increased main rotor blade pitch, and so the engine stays at the same RPM's.
This overall increase in pitch that makes the heli climb is called collective control. So basically on a 4ch helicopter the angle of the blades is fixed but on a 6ch helicopter the angle of the blades changes to give more lift and control. Language UK. Currency GBP.
