2. Pairing to TX
1
Power off the TX.
2
Press and hold the program button of the RX/ESC and turn on RX/ESC, the LED will flash slowly.
3
Next, hold the Bind button of TX and then power on TX. TX LED will flash when binding starts.
4
When the RX LED Solid On, this means RX has paired to TX successfully. If TX LED stops flashing and RX is not bound, move
closer and start over at step 1.
3. Setup Your Radio
a) Reverse Switches, Trimmer and ATV Knob
1
If the truck turns the wrong direction when driving, you can reverse the direction with the reverse switch. The same principle can be
applied to forward and reverse
2
Use the steering trim to make minor adjustments to keep truck going in a straight line when not steering.
3
Use throttle trim to adjust if truck does not stop when not using the throttle.
4
Use the ATV Knob to adjust the steering endpoints. This can be used to make the truck steer more or less sharp.
b) Programming the End-points
To set the Right End-point of Steering
1
Turn on TX and RX.
2
Hold the steering wheel at right-most position and then hold the setup key for 10+ seconds until LED flashes.
3
Now move the steering wheel until the front wheel is at the right-most position. Then hold the steering wheel at this position and
press the setup key to save this End-point.
4
The LED will blink 4 times and then return the TX back to normal operation.
To set the Left End-point of Steering
1
Similar to above, only difference is hold the steering at left-most position and then hold the setup key for 10+ seconds.
Throttle End-points Programming
1
Similar to steering end-point programming, hold the throttle at forward-most position to set forward end-point, (Reverse-most
position to set reverse end-point) hold the setup key for 10+ seconds.
4. Low Battery Indicator
1
During normal operation, the LED should be solid ON.
2
Once battery gets too low, the LED will begin flashing very slowly to indicate battery is low. You should replace
with a new battery replacement as soon as possible.
