Say you have to make a sudden turn or dodge an obstacle. The AVC system lets you do that without having to back way off the power. It reads your control inputs, senses your car's trajectory and makes as many as 180 steering and power adjustments per second so you can hold the line without holding back. It feels completely natural too. There is no lag in response or limits on your control. You simply feel dialed in at any speed.
From the people who pioneered 2.4GHz radio systems for model hobbies comes the ultimate performance upgrade for RC cars, buggies and trucks – the Spektrum AVC® (Active Vehicle Control®) system. Using a combination of steering and throttle management features, this system gives you the freedom to push the limits and realize your vehicle's true potential. Start scrolling to see how.
On rugged terrain, it can be tough to maintain control when driving fast. The AVC system's steering and throttle management work in harmony to keep you headed in the right direction.
automatically adjusts power output to help keep the rear in line with the direction you want to go.
reacts faster than you ever could to keep your front wheels pointed in the right direction when they get knocked around by terrain.
The AVC system helps you nail big jumps perfectly every time. Just line up with the ramp and punch the throttle. Steering management will help keep you aimed right down the middle no matter how fast you're going.
At the heart of the AVC system is a Spektrum SRS4200, SRS4201 or SRS4220 receiver. These 4-channel receivers use a combination of sensors and exclusive software to make their lightning-fast steering and power adjustments. The amount of stability the system provides is adjusted using specially equipped Spektrum transmitters.
Steering assist helps keep your front wheels pointed in whatever direction you command when they get bumped around by rough terrain. If the steering wheel is released or returned to center, it can hold the vehicle in a straight line during aggressive acceleration and braking.
Throttle assist works a lot like the traction control or stability system on a full-scale car. It senses any drift in momentum or direction and instantly adjusts power to prevent tail slides. The result is less wheel spin and faster acceleration when coming out of a turn or driving on a slippery surface. You get maximum traction when you need it most.
The amount of stability assistance an AVC system delivers can be adjusted on the fly using a compatible Spektrum transmitter. You can even turn the system off if you want. The number and range of adjustments you can make depends on the transmitter.
Equipping a vehicle with the AVC system is as simple as installing the Spektrum™ SRS4220 receiver. The entire system – receiver, sensors and software - is integrated in this tiny unit that weighs less than half an ounce (10.9 grams). You will need a compatible Spektrum transmitter to activate the system and make adjustments. Although not required, a high-performance digital steering servo is recommended.
Calibration is required anytime you bind or re-bind an AVC receiver to your transmitter. You should also perform the calibration process anytime you transfer an AVC receiver from one vehicle to another. An AVC receiver that comes installed in a Ready-To-Run vehicle does not need to be calibrated unless you re-bind it to its transmitter or bind it to a new one. To learn how to calibrate an AVC receiver, watch this video.
Not with the AVC system active. Most sanctioned races prohibit the use of electronic stabilization. However, all AVC receivers come equipped with a ‘blinky’ mode that lets you completely deactivate the system. While in blinky mode, the receiver’s LED light will blink so race officials can confirm it has been disabled. To learn how to engage blinky mode, watch this video.
AVC receivers will work with all Spektrum® surface transmitters, but the experience will differ depending on the amount of channels your transmitter has. All 2-channel transmitters, except for the DX2E, lock the AVC system’s steering and throttle management gain at 50%. The DX2E, as well as all 3-channel Spektrum transmitters, let you adjust steering and throttle management simultaneously. For the best experience, however, we recommend a 4-channel Spektrum transmitter with AVC programming. Using this programming you can assign separate switches for steering and throttle management so you can adjust each independently. You can see if your transmitter is compatible here.
Yes, but it is not recommended. Some of these receivers must be mounted exactly as they were in the Ready-To-Run vehicle in order to calibrate properly.
Yes. If you are using a 2-channel Spektrum transmitter other than the DX2E, you can deactivate the system by putting the AVC receiver in ‘blinky’ mode (see question 3). If you are using a DX2E or 3-channel Spektrum transmitter, you can effectively disable the AVC system by dialing the combined steering and throttle management setting back to 0%. A 4-channel transmitter with AVC programming will allow you to disable steering or throttle management independently.
No. AVC receivers are exclusively designed for use with Spektrum transmitters.
