RADIO SYSTEM BASIC ADJUSTMENTS
Throttle Neutral Adjustment
The throttle neutral adjustment is located
on the transmitter face and controls the
forward/reverse travel of the throttle
trigger. Change the adjustment by
pressing the button and sliding it to the
desired position. There are two settings
available:
50/50
: Allows equal travel for both acceleration and reverse.
70/30
: Allows more throttle travel (70%) and less reverse travel (30%).
We strongly recommend to leave this control in its factory
location until you become familiar with all the adjustments and
capabilities of your model.
Note:
50/50 is the default factory setting. To change the throttle
neutral adjust position, turn the transmitter off before adjusting the
neutral position.
Steering Trim
The electronic steering trim located on the
face of the transmitter adjusts the neutral
(center) point of the steering channel.
Multi-Function Knob
The Multi-Function knob can be programmed
to control a variety of functions. From the
factory, the Multi-Function knob controls
steering sensitivity, also known as exponential
or “expo.” When the knob is turned
counterclockwise all the way to the left (default position), expo is
off and steering sensitivity will be linear (the most commonly used
setting). Turning the knob clockwise will “add expo” and decrease
the steering sensitivity in the initial range of steering wheel travel
left or right from center. For more detail on steering exponential,
refer to pages 13-14.
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, slowly adjust the
steering trim control on
the transmitter until they are pointing straight ahead.
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.
