Tilting (vertical)
Tip the joystick upwards to turn the camera vertically upwards and tip it downwards to turn the camera downwards. The
camera rotation is limited upwards by the horizontal plane or downwards by the vertical axis.
Performance will change considerably near the vertical axis according to whether the AUTO FLIP
is on or not (default
setting is on).
WithAUTO FLIP off, the camera will stop in perfectly vertical position and will stop turning when the joystick is tipped
downwards.
WithAUTO FLIP on, the camera will proceed over the vertical axis when the joystick is tipped downwards. This is
because, when the vertical axis is reached, the camera flips automatically by 180 degrees and resumes the initial
trajectory.
The AUTO FLIP
function can be used to follow a subject arriving in a certain direction passes under the camera and
continues in a straight line. To do this, hold the joystick tipped downwards following the movement of the subject. Observe
that in this case the joystick performance after the camera passes over the vertical axis opposite to the normal axis
because tipping the joystick downwards will turn the camera upwards.
Normal operation of the joystick will be resumed as soon as the downward tip is interrupted (also only for an instant). At
this point, to follow the subject in the same direction, you will need to tip the joystick upwards, as you would normally.
