Pulling the throttle lever back causes the RC EYE One to drop. Pulling the throttle lever back all the way
shuts off the engines.
During flight close above the ground and during take-off, turbulence and air flow can be
experienced which may affect the "RC EYE One". A quicker response to the controlling motions
and slight swerving of the "RC EYE One" forwards, backwards or to the side may result from
this. This so-called ground effect is no longer present starting at a flight height of about 50 cm.
