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 find 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.

Binding and Calibrating the SRS4210 Receiver
You must calibrate the receiver each time it is placed in bind mode.
IMPORTANT:
The following sequence of steps must be followed in order for AVC to function properly.
1. Insert the Bind Plug in the BIND port on the receiver.
2. Power on the receiver. The orange LED flashes, indicating the receiver is in bind mode.
3. Center the ST TRIM and TH TRIM on the transmitter.
4. Put your transmitter in bind mode.
5. The bind process is complete when the orange LED on the receiver is solid.
6. Pull the transmitter trigger to Full Throttle.
7. Push the transmitter trigger to Full Brake, then return the trigger to center.
8. Turn the transmitter steering wheel to Full Right.
9. Turn the transmitter steering wheel to Full Left, then return the steering wheel to center. The orange LED flashes once.
10. Remove the bind plug once the calibration and binding process is complete.
11. Power off the transmitter.
IMPORTANT:
You must rebind the transmitter and receiver if you:
•
Change the servo reverse after binding
•
Change the travel after binding
•
Want to use the receiver with a different model memory
If you change the servo reversing or travel adjust after binding, AVC will not work properly.
Disabling the Stability Assist Function
If you participate in organized racing, you may be required to turn AVC technology off. To turn off AVC technology, insert a second
Bind Plug in the Disable port before binding.
IMPORTANT:
You must calibrate the receiver each time it is placed in bind mode. To activate AVC, see the steps in BINDING AND
CALIBRATING THE RECEIVER.
Bind Transmitter to SR410 Receiver
1. Insert a bind plug in the receiver’s BIND port.
2. Power on the receiver and wait until the receiver LED begins flashing.
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 flashes on top of the transmitter.
8. When the bind process is complete, the transmitter and receiver LEDs stop flashing and turn solid orange.
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.
