BASE MENU (SERVO REVERSING, SUB-TRIM AND END POINT ADJUSTMENT)
SETTING
SUB-T MENU [Servo Sub-Trim]
The Sub-Trim function allows you to correct the Neutral Trim setting for the Steering, Throttle, Auxiliary 1 and Auxiliary 2
channels, making it possible to center the Trim Switches while ensuring the servo horns remain centered.
It's not unusual that when you center a servo and install the servo horn, the servo horn is not exactly centered. The Sub-Trim
function allows you to center the servo horn exactly, without altering the servo End Point travel. This is especially useful when
using a Mix, such as Four Wheel Steering Mixing. For example, you can use the Sub-Trim function to adjust the Neutral Trim
setting of your Front and Rear Steering servos independently to ensure your model tracks straight.
Before changing the Sub-Trim values you should set the Steering and
Throttle Trim to 0% using the Trm1 and Trm2 Trim Switches.
Installing the Control Servo Horns:
1) Install the servo horn (or servo saver for the Steering servo) onto your servo,
making sure that the servo horn (or servo saver) is as close to being
centered as possible. In some cases, you can get the servo horn closer to
being centered by rotating the servo horn 180º and reinstalling it.
Selecting the Menu and Channel:
1) From within the SETTING menu, press the UP or DOWN keys to highlight the BASE
menu. BASE ST REV NOR will be highlighted.
If the cursor is flashing over Channel/Options, press the ENTER key to stop the
cursor flashing, then press the UP or DOWN keys to select the BASE menu.
2) Press the BACK key so that the cursor is flashing over Channel/Options.
3) Press the UP or DOWN keys to highlight the desired channel you would like to
change the Sub-Trim value for, then press the ENTER key.
Changing the Servo Sub-Trim Values:
1) Press the DOWN key to highlight SUB-T 0.
2) Press the ENTER key, then press the UP or DOWN keys to Increase or Decrease the
Sub-Trim value only enough to center the servo horn.
BASE SUB-T setting range is R150 to L150 (or H150 to B150, or H150 to L150). The default setting for all channels is 0.
IMPORTANT:
Changing the Sub-Trim values will alter the servo's End Points. After changing the Sub-Trim values, use the
End Point Adjustment function to Reset the servo End Point Adjustment Percentage Values. For more information, see the
EPA Menu section on pages 25 and 26.
SETTING MENU
EPA MENU [End Point Adjustment]
The End Point Adjustment function allows you to adjust servo travel in each direction. This makes it possible to balance servo
travel in both directions and set the maximum desired amount of servo travel. For example, on a gas-powered model, if you pull
the Throttle Trigger and the carburetor does not open completely, you can Increase the Throttle High End Point Adjustment so
that the carburetor opens completely. Another example is with steering. If your model turns sharper to the Right than to the Left,
you can Increase the Steering Left End Point Adjustment to balance the steering.
