e) Basic Information Relevant to the Control of Quadrocopters
Before you fly your model, you should first familiarise yourself with the control possibilities open to you and thereby
be able to fly safely.
The symmetrical setup of the model makes it very difficult to assign the alignment (front/rear). Therefore, the two front
propellers are of blue plastic and the two rear propellers of orange plastic. Red and blue LEDs are installed on the
motors in addition to this.
The quadrocopter is controlled via the two control sticks at the remote control transmitter. The following functions are
available:
Pitch Function
With the pitch function you can control the flight altitude of the quadrocopter (see figure 8). The left control stick (also
see figure 1, item 8) is used for control. To that effect, the control stick can be moved forward and backward. Unlike
the other control functions, the stick does not keep springing back to the centre position.
Depending on the control stick position, the speeds of the four propellers change. If the control stick has been pulled
all the way to the body, the motors are switched off.
If you push the control stick from the bottom position forward, the propellers start up and increase the speed according
to the position of the stick.
Once the control stick is in the centre position, the propeller speeds should be high enough for the quadrocopter to
hover.
If the control stick is pushed forward further, the quadrocopter will rise.
If the control stick is pulled back, the quadrocopter drops.
