EPA Setting on CH2 (Brake/Reverse), with ‘DT4’ Button
This function allows the quick change of reverse/braking EPA without having to access the on screen menu using the
button and then scroll through the various screens, and is useful for making quick function changes when at the
track or similar. The button works the same as ‘DT1’ above, with the same range of change and increments of change.
Also, changes made using the ‘DT4’ button will show on the LCD display.
Channel 3
The 3rd channel on the 3CFM works in such a way that a single push of the button on the transmitter’s grip will cause
the servo arm to move through a set amount of travel in one go. A second push of the button will cause the servo arm
to return to its start point (neutral). An ideal application for this would be the reverse operation in an engine powered
car, where a gearbox is required to effect the change from forward movement to reverse movement.
Trim Function Setting on CH3
This function allows you to trim the 3rd
channel servo in the model to set a
specific neutral position.
Press the
button nine times in normal
display mode to enter the Trim setting
menu for Channel 3.
Start with the percentage setting at -0%
using the ‘DT1’ button as necessary.
Once the servo arm is fitted to the servo,
you can fine-tune the arm’s position to set your preferred neutral position. The changing range is from -0% up to -
100%, moving in 1% increments. It may be necessary to re-position the servo horn whilst doing this.
Note: It is important that you ensure the 3rd channel button is in its neutral position before setting a servo
up in your model. If the 3rd channel button is in the correct position, once you select the Trim function for
channel 3, you should immediately notice the servo’s output arm moving in response when you press the
‘DT1’ button to either the left or right. If it does not, push the 3rd channel button on the transmitter once
and the servo will return to its neutral position (the servo arm will move back to neutral). Now the servo arm
should respond to adjustments to the trim function using the ‘DT1’ button.
EPA Function Setting on CH3
This function allows you to trim the
3rd channel servo’s EPA in the model
to set a specific percentage/amount of
movement from neutral.
Press the
button ten times in normal
display mode to enter the EPA setting
menu for Channel 3.
Use the ‘DT1’ button to increase or
decrease servo arm movement as
required. The changing range is from +0% up to +100%, moving in 1% increments.
Note: Press the 3rd channel button and the servo arm will move through a set amount of travel. If the amount
is too much or too little, you can fine-tune it using the EPA function.
