Setting Up The Antenna - Traxxas REVO 3.3 53097-3 Owner's Manual

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 TQi to
default settings (see page 14)
and re-program the OptiDrive
Module. For programming
with aftermarket radio
systems, please see our
website.
OptiDrive Operation
• Green "Function"
Shift allowed
• Red flashing "Function"
Low battery, see pg. 12
• Red "Sensor"
a) Sensor, throttle or shift circuit is
broken. Possible disconnected or
broken sensor, throttle or shift
wires. Possible damaged sensor.
b) Receiver has lost signal from the
transmitter, the OptiDrive has
entered fail-safe (throttle and shift
servos become unresponsive).
• Blue flashing "Sensor"
Normal operation as vehicle
moves. Indicates signal pulse from
sensor. Depending on the rotor
position, solid blue or off when
vehicle is at rest.

SETTING UP THE ANTENNA

The receiver antenna has been setup
and installed from the factory. The
antenna is secured by a 4x5mm set
screw. To remove the antenna tube,
simply remove the set screw with the
included 2mm wrench.
When installing the antenna, first
slide the antenna wire into the
bottom of the antenna tube until
the white tip of the antenna is at the
top of the tube under the black cap.
Next insert the antenna tube into
the mount; then, install the set screw
next to the antenna tube. Use the
supplied 2mm wrench to tighten the screw just until the antenna
tube is securely in place. Do not overtighten. Do not bend or kink the
antenna wire! See the sidebar for more information.
PROGRAMMING THE OPTIDRIVE
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 there is 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 TQi Transmitter to its factory default shift settings:
A. Turn transmitter off.
B. Hold both MENU and SET.
C. Turn transmitter on.
D. Release MENU and SET. The transmitter LED will blink red.
E. Press SET to clear settings. The LED will turn solid green and
Antenna
the transmitter is restored to default.
Tip
Note: DO NOT reverse the servos 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 to neutral.
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.
