Velineon VXL-4s Brushless System

Traxxas Velineon VXL-4s Brushless System

Extreme Brushless Power – Velineon VXL-4s

The Velineon® VXL-4s brushless system delivers extreme RC power with the massive torque of the Velineon 540XL motor and the innovative VXL-4s™ ESC. New High-Resolution Linear Braking gives the most precise and intuitive braking Traxxas has ever offered. Built-in telemetry and selectable 6.0 or 7.4-volt BEC transform 14.8 volts of LiPo power into staggering performance. The extra-large heat sink keeps the ESC running cooler for longer sessions.

Velineon 540XL Motor

• Long-format brushless motor

• 4-pole, 2400 Kv

• 5 mm output shaft

• Low-maintenance design

High-Voltage BEC

The integrated high-voltage BEC allows you to select 6.0 V for standard servos or 7.4 V for high-performance servos such as Traxxas 2280, 2255, and 2250. Brushless high-torque servos like the High-Torque 600 gain over 20% more torque at 7.4 V. Voltage selection is quick and easy using the Traxxas Link app.

High-Resolution Linear Braking

Traxxas’ High-Resolution Linear Braking is a patent-pending innovation that delivers ultra-smooth and intuitive braking control. The advanced communication loop ensures instant response to driver input, from gentle speed corrections to hard braking into corners. The Traxxas Link app allows you to fine-tune braking force to match your driving style or conditions.
