The Technique of Adjusting the Pitch of RC Helicopter

When the assembly of the RC helicopter fuselage is completed, check the electrical equipment and finish the basic reception of the frequency test, then, a very important step is to adjust. The basic steps are mainly to confirm the relationship between the Collective Pitch and the transmitter, and the relationship between the Cyclic Pitch and the gyroscope, as they relate to the helicopter flight characteristics.

Many people are obsessed with the WLtoys RTF helicopter these days, and I heard that many of you have purchased one of two back home deciding to have a nice flight. It’s good for you to enjoy such fascinating hobby, but to enjoy it properly, I will suggest you know more about the RC helicopter as it’s a big complex world. Except for the WLtoys helicopters, the Trex 450, is a hit recently and sold out everywhere online.

What is the collective pitch?

In the case of remote-controlled helicopters, the collective pitch is used to maintain a height level. The collective pitch refers to the fact that the two rotors simultaneously change the same angle up or down to provide helicopter lift or reverse thrust, but also note that when the angle becomes larger, provide the equivalent speed to maintain the lift. Can your battery, motor provide enough power? So the adjustment is to confirm when the throttle is from 0 to 100, how much is the corresponding collective pitch.

What is a cyclic pitch?

It means that the angle of the rotor changes when you move the aileron to control it forward, backward, left and right sides flying, and the adjustment is to determine when the remote controller is lifted and the aileron rocker is pushed to the bottom, how is the Cyclic pitch angle. This can determine how fast the helicopter reacts to the body's change on the axis.

About how exactly to adjust the pitch, we will talk about it the next time. What you need to prepare is that you might need a digital pitch gauge as the built-in digital gyro can detective the pitch of the blade automatically and display on the LCD with backlight.
