SRS4201 STABILITY ASSIST RECEIVER
AVC – ACTIVE VEHICLE CONTROL
The Spektrum SRS4201 receiver features Active Vehicle Control™ (AVC
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 SRS4201 receiver also enables you to quickly turn AVC on or off if you participate
in organized racing.
NOTICE: You must use digital servos with the SRS4201 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 transmitter comes prebound to the vehicle; however, if you need to
rebind or calibrate the receiver, follow the instructions below.
Insert the Bind Plug in the BIND port on the receiver.
1. Connect a fully charged battery pack to the ESC.
2. Power on the ESC. The orange LED fl ashes, indicating the receiver is in bind mode.
3. Center the ST TRIM and TH TRIM dials on the transmitter.
4. Press and hold the BIND button while powering on the transmitter.
5. Release the BIND button when the orange LED slowly fl ashes. The transmitter and
receiver are linked when the orange LED 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 fl ashes once.
10. Remove the Bind Plug, then power off the receiver to save the settings.
11. 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
® ) technology that
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 fi rmly on
the ground, give the car about 1/8 throttle for 30 seconds. The right side tires should spin
freely during this time. Repeat this with only the right side tires fi rmly on the ground,
allowing the left side tires to spin freely. Repeat this 2–3 times.
2. Check for free suspension movement. All suspension arms and steering components
should move freely. Any binds will cause the car to handle poorly.
3. Charge the battery.
4. Check the calibration of the ESC. If recalibration is required, refer to the Tazer Mini
Brushless ESC section.
5. Adjust the transmitter settings to your desired confi guration.
DRIVING PRECAUTIONS
® , DSM2 ® or DSM Marine
• 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
can cause fasteners to loosen over time.
• Do not drive the vehicle in tall grass. Doing so can damage the vehicle or electronics.
• Stop driving the vehicle when you notice a lack of power. Driving the vehicle when
the battery is discharged can cause the receiver to power off. You may lose control
of the vehicle.
• Do not apply the throttle in forward or reverse if the vehicle is stuck. Applying throttle
in this instance can damage the motor or ESC.
• After driving the vehicle, allow the electronics to cool to ambient temperature before
using the next battery pack.

RUN TIME

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 airfl ow to the ESC and motor.
• Change the gearing to a lower ratio. A lower ratio lowers the operating temperature of
the electronics. Use a smaller pinion gear or larger spur gear to lower the gear ratio.
• Use a battery pack with a higher mAh rating.
