Say you have to make sudden turn to dodge an obstacle. AVC technology reads your command inputs, senses your car’s trajectory and makes as many as 180 steering and throttle corrections per second to keep it precisely on the path you command. It does all of this so fast that it feels completely natural. There is no lag in response or limits on your control. You simply feel like you’re driving an expertly tuned car that handles beautifully at any speed.

Another Innovation By

From the people who brought 2.4GHz technology to radio control comes another breakthrough that’s going to revolutionize how you drive – Spektrum AVC™ (Active Vehicle Control) technology. Using Heading Hold and Throttle Management, this technology makes it possible for drivers of all skill levels to drive faster with more control. Start scrolling to see how.

On rugged terrain, it can be tough to maintain control when driving fast. AVC technology’s Heading Hold and Throttle Management work in harmony to keep you headed in the right direction.

Throttle Management

automatically adjusts throttle output to help bring the vehicle’s rear in line with the direction you want to go.

Heading Hold

will react faster than you ever could to keep your steering wheels precisely pointed in the direction you command when they get knocked around by impacts with terrain.

When tackling big jumps, AVC technology helps you nail them perfectly every time. Just line up with the ramp and punch the throttle. Heading Hold will keep you aimed right down the middle no matter how fast you’re going.

Let's Elaborate

Patent-pending AVC™ (Active Vehicle Control) technology uses a combination of sensors and software algorithms to automatically adjust steering and throttle output, faster than humanly possible, so you enjoy a more stable and controlled driving experience. The stability it provides can be adjusted to suit your preference and feels completely natural. There is no lag in response or limits on your control. With AVC active, you’ll feel like you’re driving a finely tuned vehicle, one that handles with precision at any speed and through every turn.

Heading Hold

Heading Hold allows you to drive faster with the confidence of complete control. Heading Hold manages steering output by automatically keeping a vehicle’s tires aligned in the direction you chose. It will also precisely maintain vehicle direction when steering is returned to center, regardless of the amount of traction or ruggedness of the terrain. With Heading Hold, hitting a big jump is as easy as lining up and punching the trigger.

Throttle Management

Throttle Management helps you maintain maximum grip in the most challenging environments. Working in harmony with Heading Hold, it automatically adjusts RPM to minimize wheel spin and tail slides so you can accelerate faster with more control. Whether you’re hitting the throttle at the apex of a turn or driving on a slippery surface, Throttle Management will help maximize traction when you need it most.

Choose the setting that is right for you

The amount of stability assistance AVC technology provides can be adjusted to suit any combination of skill level, driving style and terrain. Depending on which Spektrum transmitter you use, adjustments can be made using programming functions or a steering rate knob. AVC functions can even be turned off completely for a more traditional driving experience.


Frequently Asked Questions

  1. Is the AVC system integrated?

    The entire system is integrated into the SRS 4200 4-channel DSMR™ receiver. No additional components are required.

  2. What needs to be done to setup or calibrate the AVC technology system?

    The system comes fully calibrated out of the box for the Vaterra® Hälix™ or Losi® Ten Rally-X vehicles. Calibration is only required after a re-bind.

  3. Can you participate in sanctioned races with AVC technology?

    No, most racing classes won’t allow any stabilization assistance of any kind. However, a blinky mode has been incorporated in the AVC receiver, this completely turns off AVC technology, visually showing race officials that the system has been disabled. Establishing blinky mode is as easy as inserting a bind plug in a dedicated port and binding your transmitter.

  4. What transmitters does AVC work with?

    AVC will work with all Spektrum® surface transmitters, but the experience may change depending on the amount of channels your transmitter operates with. Two-channel transmitters (excluding the DX2E included with the Vaterra Hälix and Losi Ten Rally-X vehicles) will not allow for full adjustments to be made, so AVC technology will only be 50 percent active when used in this arrangement. With three-channel transmitters, both Heading Hold and Throttle Management are adjusted simultaneously. When paired with a four-channel transmitter you can adjust Throttle Management and Heading Hold independently.

  5. Can an AVC receiver be removed and used in another vehicle?

    Yes, but it is not recommended. The SRS 4200 AVC system was specifically designed and optimized for the Vaterra Hälix and Losi Rally-X.

  6. Can the system be disabled?

    Yes. The system is fully adjustable and can be disabled through your transmitter. On the DX2E included with the Vaterra Hälix and Losi Ten Rally-X vehicles, adjusting AVC sensitivity level is as easy as turning the steering rate knob clockwise to increase sensitivity or counterclockwise to decrease sensitivity. To fully disengage the system, the knob must be fully turned counterclockwise. For all other compatible Spektrum transmitters, adjustments vary based on the number of available channels and programming interface.

  7. Are non Spektrum transmitters compatible with AVC?

    No. The SRS 4200 AVC receiver is only compatible with Spektrum transmitters. However, the level of adjustability varies by the transmitter used.
