The Full-Throttle Freedom of AVC Technology

The receiver's built-in AVC (Active Vehicle Control) traction control system works behind the scenes, making hundreds of throttle and steering adjustments per second, so more of the motor's power is translated into ballistic speed and acceleration instead of just flying dirt. The patent-pending AVC system adds a level of performance that simply cannot be found with any vehicle from any manufacturer other than Horizon Hobby. Like traction control in your full-scale vehicle, you can activate or deactivate the system on the fly and adjust the level of stability based on driving conditions. Any RC vehicle can go fast and with AVC you can go faster while maintaining optimum stability in all driving conditions.
