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 red rotors are considered direction indicators. They mean "front". The explanations are all based
oncongurationoftheremotecontroltomodeII.

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 via the integrated sensors.

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
