11. Information for First Take-Off
a) Hover Flight
For a simpler and consistent explanation of steering, classic terminology is used here as well. This comes
from ight language and is widely used.
Directional descriptions are always to be interpreted from the perspective of a "virtual" pilot in the model.
The two black rotors are considered direction indicators. They mean "front". The explanations are all based
on conguration of the remote control to mode II.
Hovering denotes a ight status in which the quadrocopter neither rises nor falls so that the upwards directed uplift
force is equal to the downwards directed weight.
Push the throttle lever (gure 3, item 3) forward to increase the motor speed and lift up the quadrocopter. Pulling the
throttle lever back causes the quadrocopter to drop. If you leave the throttle stick in the middle area, the quadrocopter
will roughly maintain its height.

During ight close above the ground and during take-off, turbulence and air ow can be experienced which
may affect the quadrocopter. A quicker response to the controlling motions and slight swerving of the quad-
rocopter forwards, backwards or to the side may result from this. This so-called ground effect is no longer
present starting at a ght height of about 50 cm.
