ACRO 45
The Trim Offset Memory Function allows you to test fly your
aircraft and correct for any built-in trim requirements. After you
adjust the aileron, elevator and/or rudder trim levers during test
flights, the trim levers are no longer in their center, or neutral,
positions. The use of trim offset allows you to return them to their
central or neutral positions without readjusting the linkages.
This function is very important when switching from model to
model. It allows your trims to remain in their neutral positions.
With the use of this function, you can easily switch among the
10 model memories without readjusting for each airplane’s trim
positions.
In the Function Mode, select Trim Offset Memory using the UP or
DN key and access by pressing the UP and DN keys
simultaneously.

Setting Trim Offset
Example: aileron trim. Trim is offset to left. Access the Trim Offset
Function and see Figure 1 below.
At this time, press the + or - keys and the display shows (2) and
memorizes the existing position. Next, return trim to center and
press the CLR key. Display shows (3) and memorizes the trim
offset value and the servo is returned to its first trim position.
Note: If trim is not returned to the center, the trim memory
position will not be stored.
Note: If the offset value is too large, a warning will sound when
you return the trim levers to center, and the display shown in (4)
will appear.
At this time, you should return the applicable trim lever to the
corrected position. OVER will disappear from the LCD. It is easy
to recognize the applicable trim channel as it will be the one
next to where OVER appears on the LCD.
Press the CLR key to clear the trim offsets from the transmitter’s
memory. It is recommended that you adjust the applicable
mechanical linkage accordingly.
To clear the trim offset adjustments, press the Select key and then
the CLR key. The display will appear as Figure 5.
To exit from Trim Memory Offset, press the UP and DN keys
simultaneously to exit the Trim Memory Offset function.
