c) Cutting the Motor
The running motors can be turned off as follows:
• THROTTLE to zero, YAW to full deflection to the right, PITCH and ROLL to neutral
• Stop rotors
• Red LED is off, green LED is permanently lit („ready to fly“)
d) Hover Flight
For a simpler and consistent explanation of steering , classic terminology is used here as well. This comes
from flight language and is widely used.
Directional descriptions are always to be interpreted from the perspective of a „virtual“ pilot in the model. The direction
indicators on the landing leg are deemed to be „in front“. The explanations are all based on configuration of the remote
control to mode 2.
Hovering denotes a flight status in which the QuadroCopter neither rises nor falls so that the upwards directed uplift
force is equal to the downwards directed weight. This is achieved approximately in mid throttle setting (but indepen-
dent of a possible payload).
During flight close above the ground and during take-off, turbulence and air flow can be experienced which
may affect the QuadroCopter. A quicker response to the controlling motions and slight swerving of the
QuadroCopter forwards, backwards or to the side may result from this. From a height of about one meter,
this effect is no longer noticeable. The QuadroCopter can now be controlled more easily and more precisely.
e) Yaw
Yaw denotes the rotation of the QuadroCopter
around the yaw axis (vertical axis).
This movement either occurs unintentionally due
to the speed torque of the rotors or intentionally as
a flight direction change.
For the QuadroCopter, this movement is not
controlled by a tail rotor, but through speed variation
of the individual rotors to each other.
Point (1) indicates „forwards“.
