AVC – Active Vehicle Control
The Spektrum™ AVC™ stabilization system adds a whole new level of control to
your RC driving experience. AVC technology utilizes sensors to adjust steering and
throttle output, providing you with a more stable and controlled driving experience.
Spektrum SRS4200
The Spektrum SRS4200 receiver features 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.

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, DSM2 or DSM Marine receiver, the ST. RATE knob controls the steering dual rate.
Driving Precautions
• 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.
• 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.
CAUTION: Do not discharge a LiPo battery below 3V per cell. Batteries discharged
to a voltage lower than the lowest approved voltage may become damaged,
resulting in loss of performance and potential fi re when batteries are charged.
• Do not apply the throttle in forward or reverse if the vehicle is stuck. Applying
throttle in this instance can damage the engine.
• Let the engine cool to ambiant temperature between runs.
