Servo Reversing Switches
The servo reversing switches are located on the front of the
transmitter, next to the on/off switch. Moving a switch reverses the
direction of the corresponding servo. Each switch corresponds to a
channel, as shown below. For example, if you turn the steering wheel
to the right and your front wheels turn left, you would move the
channel 1 switch to correct the servo direction. It may be necessary
to adjust the corresponding trim control after moving a switch. The
default position for the servo reversing switches is shown.
PROGRAMMING THE OPTIDRIVE
®
ESM
The OptiDrive ESM electronically monitors
vehicle speed and controls forward and reverse
shifting. Controlling the shift action electronically
rather than by mechanical systems reduces the
number of components in the transmission. The
transmission weighs less, there is lower rotational
mass for quicker acceleration, and constant drive engagement for
smooth power delivery.
The OptiDrive module prevents the transmission from changing
directions while the truck is in motion. The truck must be completely
stopped to change directions, regardless of the position of the shift
selector switch on the transmitter.
The OptiDrive module is preset at
the factory.
If the transmitter throttle trim adjustment is changed, or
an aftermarket servo is installed, then the OptiDrive module will need
to be re-programmed.
1.
The engine must be shut off. The radio system must be on (receiver
and transmitter).
2.
Set the TQ 2.4GHz Transmitter to its factory default shift settings:
Set the THROTTLE NEUTRAL switch to the 50/50 setting.
Set the THROTTLE TRIM to the center “0” setting,
then adjust the THROTTLE TRIM until the carburetor
closes. This should require only slight adjustment. If
more than 15 degrees of adjustment is required (see
illustration), the throttle linkage must be adjusted.
Set the CHANNEL 2 SERVO REVERSING SWITCH to the right position.
Set the CHANNEL 3 SERVO REVERSING SWITCH to the right position.
DO NOT change the position of any of the servo reversing switches
after programming the OptiDrive. If settings were changed after
programming the OptiDrive, it will have to be reprogrammed.
3.
With the throttle at neutral, press and hold the
SET button until the Function LED flashes green
twice and then release the button immediately.
You are now in programming mode.
4.
Pull the transmitter throttle
trigger to the full throttle
position. Hold it there until
the Function LED flashes
green three times.
Note:
The throttle servo will not move during programming even
though it is connected to the controller.
5.
Release the transmitter
throttle trigger allowing
it to return toneutral. The
Function LED will turn
solid green, indicating that
the shifting servo is OK to shift and the programming has been
completed. The controller is now programmed and ready to go!
Note
: If the Function LED does not turn solid green in this step,
it may be necessary to readjust the throttle linkage so that the
throttle trim is as close to the center “0” setting as possible when the
carburetor is closed.
If the transmitter throttle settings are changed, it will be necessary
to complete the programming sequence again.
If the SET button is released before the Function LED flashes
green twice in step 3, the OptiDrive will return to the normal
operation mode.
If you experience any problems during programming, turn the
receiver off, then on again, and repeat the programming steps.

systems, or to access advanced programming options, visit Traxxas.com.
THE TRAXXAS TQ 2.4GHZ RADIO SYSTEM
Default Setting
Large adjustments to the
throttle trim and/or throttle
linkage may require re-setting
the OptiDrive to maintain
proper shifting action.
For transmission durability,
the OptiDrive ESM limits the
model’s reverse speed to about
70% of full throttle. If settings
are changed, and you notice a
decrease in forward top speed,
you could have the OptiDrive
system reversed. Return the TQ
2.4GHz servo-reversing switches
for channels two and three
back to their default settings
and re-program the OptiDrive
Module. For programming with
aftermarket radio systems,
please see our website.
