VXL-4s Electronic Speed Control 3445

The 3440 Velineon® 4s brushless power system takes your RC experience to the extreme. 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.
