Place one finger under the rods of the auxiliary paddle of the main rotor. Lift the helicopter in this manner. The helicopter must now be positioned levelly at equilibrium. If

this is not the case, shift the flight storage battery accordingly.

After you have set the exact storage battery position, you should make a suitable marking so that you don't have to readjust the centre of gravity every time

you want to insert the storage battery after charging.

f) General Information on Controlling Model Helicopters

Before you start your model, you should first familiarise yourself with the control capabilities available to you in order to be able to safely control the model. The model

helicopter is controlled using the two control sticks on the remote control.

Transmission of the Control Commands

The control commands that you issue on the remote control are not passed on to the model 1:1, rather they are processed in the remote control's electronics in advance.

This serves to make piloting a model helicopter easier. If you e. g. increase the angle of attack (pitch) of the main rotor blades, the amount of power required will become

considerably higher. You don´t have to react to this by accelerating separately. The electronics in the remote control take care of this for you (in accordance with its program-

ming) by issuing corresponding mixed commands to the receiver electronics.

Pitch Function

Pitch specifies the angle of attack of the main rotors. The more extreme the angle of attack is, the more lift the main rotor will generate. Using the pitch function, the flying

altitude and/or the speed of a helicopter is influenced.

For this, the control stick (Figure 1, Item 18) can be moved to the front and back without always springing back to the intermediate position as with the other control func-

tions.

• If the control stick is pulled all the way to the body, then the drive motor is deactivated and the rotors are not rotating.

• If the control stick is pushed forward, the motor starts and the angle of attack of the main rotor blades is increased. At the same time, more throttle is applied.

• If the intermediate position of the control stick is reached, the helicopter should hover.

Yaw Function

Yawing describes the turning of the helicopter around the vertical axis. With the yaw function, you therefore determine the direction in which the fuselage tip points. By means

of a built-in gyro, the model automatically compensates for the rotary movements, which are not triggered by a command on the remote control, rather e. g. by the wind.

• If the stick (Figure 1, Item 18) is steered to the left, then the fuselage tip turns to the left.

• If you steer to the right, then the fuselage tip also turns to the right.

Roll Function

Using the roll function, you can move the model helicopter laterally to the right and left. Steering is performed with the corresponding control stick (see Figure 1, Item 6).

• If the control stick is steered to the left, the model will drift laterally to the left.

• Steer to the right, then the model will drift laterally to the right.

Pitch-Axis Function

Using the pitch-axis function, you can have the model helicopter fly forwards or backwards. Steering is performed with the corresponding control stick (see Figure 1, Item 6).

• If the control stick is pushed to the front, the model flies forward.

• If you pull the control stick to the back, then the model will fly backwards.
