a) Setting the Steering Trim
Push and hold the lower one of the two trim buttons (-) for steer-
ing trim (also see figure 2, item 12).
The green LED display (also see figure 2, item 8) starts to flicker
after a while. With the receiver system switched on, the servo
lever of the steering servo will turn step by step from the middle
position to the end of the trimming area.
When the green LED stops flickering, the end of the trimming
area has been reached and the servo lever stops.
Now push and hold the upper one of the two trim buttons (+) for
the steering trim (12). The green LED display (8) starts flicker-
ing again after a while and the servo lever returns to the middle
position.
When the green LED flashes briefly twice, release the trim button without delay. The middle position has been reached
and the set value is saved automatically.
The last value set is retained even after switching off and on.
When the middle position of the digital trim for steering has been set on the transmitter, the position of the servo lever
can be inspected at the steering servo and the lever installed in the correct position if required. Slight inclinations due
to the servo lever interlock can then be corrected with the trim.
Practical advice:
The trim for the steering function is exactly at the centre if the steering servo lever no longer moves if you
try operating the reverse switch (see figure 2, item 15). The steering wheel must be in the middle position
for this.
b) Setting the Driving Trim
When using a combustion engine with throttle/brake servo, the trim setting is made just as for the steering servo.
However, the two trim buttons for drive trimming (see figure 10, item 11) are used to adjust the trim value.
When using the electrical model with speed controller, the trim also needs to be set to the average value. If the speed
controller does not offer any option for teaching in the respective positions for forward, stop and reverse, the middle
position of the driving trim must be set so that the drive motor is off when the operating lever for the driving function
(see figure 1, item 3) is not pushed.
