Sub-Trim
The Sub-Trim function enables you to correct minor servo arm offsets by electronically
adjusting the center point of the servo. Sub-trim is available on all channels.
CAUTION: Only use small sub-trim values so you do not exceed the maximum
servo travel. If you fi nd the servo requires a large amount of sub-trim, return the
sub-trim to 0 and adjust the servo arm on the servo spline manually.
*Reference chart for options available for each channel:
Channel Description
Steering L (left) R (right)
Throttle B (brake) F (forward)
Aux 1 H (high) L (low)
Aux 2 H (high) L (low)
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 the throttle servo to its pre-programmed failsafe
position (normally full brakes) and all other channels will have
no servo output. If the receiver is turned on prior to turning on
the transmitter, the receiver will enter the failsafe mode, driving
the the throttle servo 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.
The Bind Screen shows the active model and supports binding
the active model memory to a receiver.
Bind
Binding is the process of teaching the receiver the specifi c
transmitter’s code called GUID (Globally Unique Identifi er) and
storing failsafe values. When a receiver is bound to a
transmitter/model memory, the receiver will only respond to
that specifi c transmitter/model memory (see ModelMatch for
more information).
Bind Transmitter to Receiver
1. Insert a bind plug in the receiver’s BIND port.
2. Power on the receiver and wait until the receiver LED
begins fl ashing.
3. Power on the transmitter.
4. Select the Model Memory you wish to bind to.
5. Select Bind from the List menu.
6. Move the throttle channel to the desired failsafe position.
IMPORTANT: The throttle channel must stay in the failsafe
position until binding is complete.
7. Scroll to Bind and press the Rolling Selector. The orange
LED fl ashes on top of the transmitter.
8. When the bind process is complete, the transmitter and
receiver LEDs stop fl ashing and turn solid orange.
9. NOTICE: Always remove the bind plug from the receiver
when the bind process is complete. Failure to do so will
cause the receiver to enter bind mode the next time you
power on the receiver.
Remove the bind plug from the receiver and keep it in a
convenient place.
