Yaw function
The torques that act on the model are balanced by the two right-turning and the two left-turning propellers, and the
quadrocopter hovers steadily in the air.
If you move the left joystick (see Figure 1, no. 13) to the left, the electronics in the model increase the speed of the
propellers that turn to the right (clockwise, as seen from above) and at the same time reduce the speed of the propel-
lers turning to the left (counter-clockwise). As a result, the entire lifting force remains the same, but the model now
has a torque that turns the quadrocopter around the vertical axis to the left as viewed from above (see dark arrows
in Figure 8).
When the left joystick is moved to the right, the propeller speeds are changed the opposite and the model turns to the
right (see light arrows in Figure 8).

Roll function
The roll function allows you to move the quadrocopter sideways to the right and to the left (see Figure 9). This can be
done with the right joystick (see Figure 1, no. 4).
When the right joystick is moved slightly to the left, the quadrocopter electronics change the propeller speeds so that
the model tilts slightly to the left and thus also flies to the left (see light arrows in Figure 9).
When the right joystick is moved to the right, the propeller speeds change the opposite way and the model flies side
-
ways to the right (see dark arrows in Figure 9).
