AVC® Technology

With a Spektrum™ AVC® (Active Vehicle Control®) system, you can literally dial in extra stability as needed so you can carve corners or nail jumps without having to back off the power. Rough terrain, slick surfaces, loose dirt—you have full-throttle freedom whatever the road throws at you.

Why drive with an AVC system?

On-Demand Traction Control

You can dial in extra stability when you want better traction on slick or loose surfaces. The AVC system will sense when your tail starts to get loose and make instantaneous throttle adjustments so more of your power goes to forward momentum and less to wheel spin. When you don’t want the extra traction, just dial back the stability and get loose.

Reach Higher Top Speeds

You can hammer the throttle and let the AVC system deal with the physics of driving fast. It will sense any drift in momentum or direction the instant it occurs and make minute steering and throttle adjustments—as many as 180 per second—so you can keep the throttle pinned. The best part is it feels completely natural. You won’t sense any interference or limits on your control. It will simply feel like you are driving an expertly tuned vehicle that handles beautifully at high speed.

Accelerate Faster

During hard acceleration, throttle and steering assist work in concert to channel more of your power into forward momentum. You’ll reach top speeds faster because you’re wasting less energy on large steering corrections and wheel spin.

Faster Cornering

Wait longer to brake when entering a turn and get on the throttle faster when leaving it. The AVC system works behind the scenes, making hundreds of minute steering and throttle adjustments per second, to keep you precisely on the line you want to hold. If you have a Spektrum transmitter with AVC programming, you can independently set the amount of steering and throttle management the system provides to better match your driving style and surface conditions.

Dialed-In Response Out of the Box

Ready-To-Run vehicles equipped with the AVC system feel "dialed in" right out of the box. Few, if any, adjustments to linkage or suspension are required to maximize performance.
