Velineon VXL-4s Electronic Speed Control, waterproof (brushless) (fwd/rev/brake)

High-Voltage BEC
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 roque at 7.4 volts with faster transit times. Selecting a voltage is quikc and easy to do using the Traxxas Link app.

High-Resolution Linear Braking
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 powrful 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.
