b) Yaw Function
"Yaw" denotes the rotation of the quadrocopter around the yaw axis (vertical axis). This movement either occurs unin-
tentionally due to the speed torque of the rotors or intentionally as a flight direction change. This movement is caused
by speed changes of the individual rotors towards each other in the quadrocopter.
If you move the left control lever to the left, the quadrocopter will turn to the left. If you move the control lever to the
right, the quadrocopter will turn to the right. If the quadrocopter turns slowly to the left in hover flight (direction of the
white arrow), the model must be trimmed with the trim (see chapter 12. c).

c) Nod Function
"Nod" denotes the movement around the cross axis which can be compared to the nodding of a head. Through this,
the quadrotor gains flight speed forwards or backwards or decelerates.
If you move the right control lever to the front, the quadrocopter will float forwards as a whole. If you move the control
lever to the rear, the quadrocopter will float backwards. If the quadrocopter drifts slowly to the rear in hover flight
(direction of the white arrow), the model must be trimmed with the trim (see chapter 12. c).
