The Velineon® 4s brushless power system takes your RC experience to the extreme with the monstrous torque of the Velineon 540XL brushless motor and innovative VXL-4s™ ESC. New High-Resolution Linear Braking provides the most intuitive and precise braking ever offered by Traxxas. Outfitted with built-in telemetry and a selectable 6.0 or 7.4-volt BEC, the VXL-4s transforms 14.8 volts of LiPo power into staggering performance. An extra large heat sink allows the ESC to run cooler for extended run times.

The Velineon VXL-4s features a high-voltage BEC with a 6.0 volt setting for standard servos and powerful 7.4 volt setting for high-performance servos like the Traxxas 2280, 2255, and 2250. Powerful brushless servos like the High-Torque 600 gain over 20% more torque at 7.4 volts with faster transit times. Selecting a voltage is quick and easy using the Traxxas Link app.

Velineon VXL-4s High-Resolution Linear Braking is a patent-pending Traxxas innovation that delivers next-level smoothness and precision. The High-Resolution communication loop allows instant response to the driver’s input for powerful and intuitive linear braking feel. From feather touch speed correction to full-power late braking to overtake on the inside line of a corner, the driver stays fully connected and in control for a competitive edge on the track. The optional Traxxas Link app adds easy control over brake force to tune for different needs and conditions.
