b) Neutral Position
When the control lever for the rudder and elevator function and the digital trimming of the control functions precisely
in the centre position, the rudder (1) and elevator (2) should be precisely at the centre as well.
Viewed from the rear, the rudders and elevators must form a level with the rudder and must not be deflected to the
top or bottom, left or right.
If the rudder and elevator are not aligned precisely, this can be corrected with the trim function.
c) Elevator Function
If the control stick for the elevator function (see figure 11) is moved down (to the rear), the elevator must deflect to
the top. The rear rudder edge must be deflected upwards by approx. 2 - 3 mm. In flight, the landing gear is pressed
downwards and the model ascends.
If the control stick for the elevator function (see figure 12) is moved upwards (to the front), the elevator must deflect
down. The rear rudder edge must be deflected downwards by approx. 2 - 3 mm. In flight, the landing gear is pressed
upwards and the model dives. This control function is required to put the model into a normal light position if it wants
to ascend too much due to a control error or a gust of wind.
