Aux channel
The Aux channel can operate as a 3rd servo channel, or as a power supply for
a personal transponder. If 5.5ms frame rate is selected in the transmitter, only
two channels, Steering and Throttle, are operational. The Aux channel can be
used to power a personal transponder or lights.
If a frame rate other than 5.5ms is selected, the Aux channel will operate as a
3rd servo channel.
IMPORTANT: When using the receiver with a DSMR transmitter, you must
re-bind any time you change the frame rate in the transmitter.
NOTICE: The DX3R, DX3R Pro and the DX4R Pro are required for 5.5ms frame rate.
Receiver Connection and Installation
Install the Receiver in your vehicle using double-sided foam servo tape. Foam
servo tape will hold the receiver in place and help isolate it from vibrations.
The receiver includes two pieces of double-sided foam tape. If you plan on
driving your vehicle in wet conditions, use the smaller piece of foam tape (
A).
Otherwise, the larger piece of foam tape (
B) prevents dust from entering the
receiver case.
Mount the antenna up and away from the vehicle in the included antenna tube.
The higher up the antenna is, the better signal it will receive.
NOTICE: Do not cut or modify the antenna.
Failsafe
The throttle failsafe position is set during binding. In the unlikely event that
the radio link is lost during use, the receiver will drive the throttle channel to
its pre-programmed failsafe position (normally neutral or full brakes). If the
receiver is powered on prior to turning on the transmitter, the receiver will enter
the failsafe mode, driving the throttle channel to its preset failsafe position.
When the transmitter is turned on, normal control is resumed.
IMPORTANT: Failsafe activates only in the event that signal is lost from the
transmitter. Failsafe will NOT activate in the event that receiver battery power
decreases below the recommended minimums or power to the receiver is lost.
