This is the Velineon VXL-6s Waterproof Electronic Speed Control from Traxxas. Few speed controls can match the VXL-6s ESC for raw, tire-shredding power. Whether tearing through the desert in the Unlimited Desert Racer or maxing out the E-Revo on a 70mph speed run, the VXL-6s ESC pours on the power you demand for over-the-top fun. Power doesn’t need to be complicated and the VXL-6s offers the same user-friendly experience you get with all Traxxas speed controls. Just plug in the batteries, press the EZ-Set button, and hold on!

Features:
Integrated telemetry for speed, RPM, voltage, and ESC temperature.
Bright multi-color LED status lights provide clear feedback.
Two-stage thermal shutdown protection with integrated cooling fan protects the VXL-6s from overheating.
Built-in two-stage low voltage detection for Lithium Polymer (LiPo) battery use provides a clear signal to the driver that the batteries are nearing their minimum voltage threshold.

The patented Training Mode is an exclusive Traxxas feature that reduces the overall power output of the VXL-6s by 50%, making it easier for inexperienced drivers to control their model. When you’re ready, simply change profiles to unleash full-throttle action.
The EZ-Set push-button setup operates and programs just like other Traxxas speed controls—eliminating the need to learn a new set of procedures.
The VXL-6s is programmable with three drive profiles:
Sport Mode – Fwd / Brake / Rev
Race Mode – Fwd / Brake
Training Mode** – 50% Fwd / Brake / 50% Rev
Patented Traxxas High-Current Connectors eliminates a common bottleneck and maintain pure, unrestricted power flow from the batteries to the brushless power system.
