Note
: The switches listed above are the factory
default functions assigned to each switch.
Each switch can be programmed to one of ten
functions including:
• Inhibit
• Aux 3-channel, 3-position (for reverse, neutral and
forward transmissions)
• Aux 3-channel, 2-position (for reverse and forward
transmissions)
• Aux 3-channel, linear (for mixture control)
• Brake (adjustable full brake position)
• Throttle exponential (allows on-the-fly throttle
expo adjustments)
• Throttle trim (coast brake position)
• Steering override (overrides steering rate
when activated)
• Steering exponential (allows on-the-fly
steering adjustments)
• Steering Rate
• Steering Trim
See page 28 for system information and assignments
for more details.
steerIng tensIon adjustMent
Steering tension is adjusted via the recessed
screw located below the steering wheel (see
Steering Tension Adjustment on the previous page).
Using a small Phillips screwdriver, turning the
screw clockwise increases steering tension while
turning the screw counterclockwise reduces
steering tension.
bIndIng
In order to operate, the receiver must be bound to the
transmitter. Binding is the process of teaching the
receiver the specific transmitter’s code called GUID
(Globally Unique Identifier). When a receiver is bound
to a transmitter/model memory, the receiver will only
respond to that specific transmitter/model memory
(see ModelMatch).
ModelMatch
The DX3R features patent pending ModelMatch
technology that prevents operating a model using the
wrong model memory. During the binding process,
the receiver actually stores the code that is assigned
to the specific model that is currently selected in the
transmitter. For example: if the model that is selected
in the transmitter is model #3, when a receiver is
bound to that transmitter, the receiver will only operate
when model #3 is selected. If another model memory
is selected (model #5 for example) the receiver will
not connect. If model #3 is again selected in the
transmitter, the receiver bound to model #3 will
connect. ModelMatch prevents operating a model
using the wrong model memory.
faIlsafe
Failsafe positions are also set during binding. In the
unlikely event that the radio link is lost during use, the
receiver will drive the servos to their preprogrammed
failsafe positions (normally full brakes and straight
steering). If the receiver is turned on prior to turning
on the transmitter, the receiver will enter the failsafe
mode, driving the servos to their preset failsafe
positions. When the transmitter is turned on, normal
control is resumed. Failsafe servo positions are set
during binding (see binding a receiver below).
calIbratIon
The DX3R can be recalibrated to ensure the
potentiometers exactly correlate with the software
providing the ultimate in accuracy. Instructions on
calibrating the radio are on page 26; however, note
that if calibration is not properly done the radio will
not function. If after calibration the steering or throttle
does not function properly (the travel is reduced or
no servo travel) it will be necessary to recalibrate the
transmitter.
