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 flight 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 configuration of the remote control to mode II.
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. Push the throttle lever (figure 3, item 4) 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 lever in the middle position, the quadrocopter will try to maintain the height.
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. This so-called ground effect is no
longer present starting at a fight height of about 50 cm.
The quadrocopter always tries to maintain its flight altitude. Due to outer influences and the low take-off
weight, this is not always possible 100%. However, this is normal for models of this size and build.
