AVC – ACTIVE VEHIClE CONTROl
The Spektrum SRS4200 receiver features Active Vehicle Control™ (AVC™) technology that
responds similar to traction control in full-scale vehicles. In addition to traction control, AVC
technology also increases steering stability during high-speed driving or while driving over
rough terrain. As you increase the AVC sensitivity, the system increases steering stability and
traction control, similar to reducing the amount of steering rate in a computer transmitter.
Reducing the sensitivity value increases the amount of steering control from the transmitter.
The SRS4200 receiver also enables you to quickly turn AVC on or off if you participate
in organized racing.
IMPORTANT: You must use digital servos with the SRS4200 receiver. Using analog servos
will reduce the performance of the system and may cause analog servos to overheat.
AVC SENSITIVITy
The ST RATE dial adjusts the sensitivity, or stability, value in the receiver. If you increase the
sensitivity, the AVC system becomes more sensitive to the vehicle drifting left or right. You
would use maximum sensitivity during high-speed driving or drag racing, when you want
the vehicle to stay in a straight line. As the sensitivity value increases, the amount of
steering travel decreases.
Turn the ST RATE knob counter-clockwise to reduce the sensitivity.
Turn the ST RATE knob clockwise to increase the sensitivity.
IMPORTANT: The ST RATE knob will only adjust the sensitivity
when the transmitter is bound to a DSMR™ receiver. When
the transmitter is bound to a DSM
receiver, the ST RATE knob controls the steering dual rate.

BINDING AND CAlIBRATING THE RECEIVER

Your Spektrum DX2E comes prebound to the vehicle; however, if you need to rebind
or calibrate the receiver, follow the instructions below.
1. Insert the Bind Plug in the BIND port on the receiver.
2. Connect a fully charged battery pack to the ESC.
3. Power on the ESC. The orange LED flashes, indicating the receiver is in bind mode.
4. Center the ST TRIM and TH TRIM dials on the transmitter.
5. Press and hold the BIND button while powering on the transmitter.
6. Release the BIND button when the orange LED slowly flashes. The transmitter and receiver
are linked when the orange LED is solid.
7. Pull the transmitter trigger to Full Throttle.
8. Push the transmitter trigger to Full Brake, then return the trigger to center.
9. Turn the transmitter steering wheel to Full Right.
10. Turn the transmitter steering wheel to Full Left, then return the steering wheel to center.
The orange LED flashes once.
11. Remove the Bind Plug, then power off the receiver to save the settings.
12. Power off the transmitter.

control test

Perform a control test with the vehicle wheels off the ground. If the wheels rotate after the
vehicle is powered ON, adjust the TH Trim knob until they stop. To make the wheels move
forward, pull the trigger. To reverse them, wait for the wheels to stop, then push the trigger.
When moving forward, the wheels should maintain a straight line without any steering wheel
input. If not, adjust the ST Trim knob, so the wheels maintain a straight line without having to
turn the steering wheel.

Before runnIng your VehIcle

1. Break in the differentials. While holding the chassis with only the left side tires firmly on
2. Check for free suspension movement. All suspension arms and steering components
3. Charge the battery.
4. Check the calibration of the ESC. If recalibration is required, refer to the Fuze Mini
5. Adjust the transmitter settings to your desired configuration.

• Maintain sight of the vehicle at all times.
• Inspect the vehicle for loose wheel hardware.
• Inspect the steering assembly for any loose hardware. Driving the vehicle off-road
• Do not drive the vehicle in tall grass. Doing so can damage the vehicle or electronics.

The largest factor in run time is the capacity of the battery pack. A larger mAh rating
increases the amount of run time experienced.
The condition of a battery pack is also an important factor in both run time and speed.
The battery connectors may become hot during driving. Batteries will lose performance
and capacity over time.
Driving the vehicle from a stop to full speed repeatedly will damage the batteries
and electronics over time. Sudden acceleration will also lead to shorter run times.
TO IMPROVE RUN TIMES
• Keep your vehicle clean and well maintained.
• Allow more airflow to the ESC and motor.
• Change the gearing to a lower ratio. A lower ratio lowers the operating temperature of
• Use a battery pack with a higher mAh rating.
