Traxxas Revo 3.3 Owner's Manual page 12

To prevent losing control of
your model, it is important
to stop at the first sign of a
weak receiver battery. Visible
warning signals include
sluggish steering response and
shortened radio range.
In addition, the OptiDrive is
equipped with a low-voltage
indicator and a failsafe circuit.
When the voltage of the receiver
battery drops below 4.3 volts,
the "Function" LED on the
OptiDrive will flash red. If the
voltage drops below 4.3 volts
for more than 2 seconds, the
OptiDrive ignores throttle and
shift signals and applies neutral
(failsafe mode). Steering will
still be operational and the
"Function" LED on the OptiDrive
will flash red. The OptiDrive
will stay in failsafe mode until
the power is turned off or the
receiver battery voltage rises
above 4.3 volts for more than 2
seconds. Anytime the "Function"
LED flashes red, it is time to stop
and recharge your battery pack.
Do not try to continue running
your model with weak receiver
batteries on board.

Steering Trim
The electronic steering trim located on the
face of the transmitter adjusts the neutral
(center) point of the steering channel.
Note: Traxxas Stability Management (TSM) must be completely
turned off while adjusting steering trim. See page 13 for TSM
adjustments.
Multi-Function Knob
The Multi-Function knob can be
programmed to control a variety of
functions. From the factory, the Multi-
Function knob controls Traxxas Stability
Management (TSM). For more detail on TSM,
refer to page 13.
USING THE RADIO SYSTEM
The TQi Radio System has been pre-adjusted at the factory. The
adjustment should be checked before running the model, in case of
movement during shipping. Here's how:
1. Turn the transmitter switch on. The status LED on the
transmitter should be solid green (not flashing).
2. Turn on the receiver switch in the model. The switch is located
on the receiver/battery compartment.
3. Position the Revo so that its front wheels are off the ground.
Make sure your hands are clear of the moving parts of the model.
4. Turn the steering wheel on the transmitter back and forth and
check for rapid operation of the steering servo. Also, check that
the steering mechanism is not loose or binding. If the steering
operates slowly, check for weak receiver batteries.
5. When looking down
at the model, the front
wheels should be
pointing straight ahead.
If the wheels are turned
slightly to the left or
right, turn off TSM (see
page 13) and slowly adjust the steering trim control on the
transmitter until they are pointing straight ahead; then, return
the multi-function knob to the desired TSM setting.
6. Operate the throttle trigger on the transmitter and check for
rapid operation of the throttle servo. When the throttle trigger
is pulled back, the carburetor should open. When the throttle
trigger is pushed all the way forward, the brake should lock.
7. Once adjustments are made, turn off the receiver on your
model, followed by the hand-held transmitter.
Range-Testing the Radio System
Before each running session with your model, you should range-test
your radio system to ensure that it operates properly.
1. Turn on the radio system and check its operation as described in
the previous section.
2. Have a friend hold the model with the engine off.
