TRAXXAS VXL-3S 2-Pole Brushless Electronic Speed Control - 3355X

Velineon VXL-3s Waterproof Features

• The VXL-3s auto-detects the motor type for brushless and sensored brushless motors.
• Traxxas High-Current Connector eliminates a common bottleneck and maintains pure, unrestricted power flow from the battery to the brushless power system.
• Built-in two-stage low voltage detection for Lithium Polymer (LiPo) battery use provides a clear signal to the driver that the battery pack is nearing its minimum voltage threshold.
• Widest range of battery options ranging from 4-cell NiMH or NiCad packs all the way up to 3S LiPo battery packs (11.1 volt)
• Training Mode is an exclusive Traxxas feature that reduces the overall power output of the VXL-3s by 50%, making it easier for new or younger drivers to control their model. When they're ready, simply change profiles to unleash full-throttle action. 
• Advanced circuit design allows sensorless brushless motors to operate with the smoothness and precision of the best brushed systems. There's no need for additional sensor wiring and hardware complexity.
• The EZ-Set push-button setup operates and programs just like other Traxxas speed controls such as the XL-5. This eliminates the need to learn a new set of procedures.
• The VXL-3s is programmable with three drive profiles:
  • Sport Mode – Fwd / Brake / Rev
  • Race Mode – Fwd / Brake
  • Training Mode** – 50% Fwd / Brake / 50% Rev
• Multi-color LED provides clear feedback
• Since the VXL-3s allows experimentation with many kinds of motors, it is equipped with numerous failsafe features to help protect against common mishaps that can cause other systems to fail.
  • Two-stage thermal shutdown protection protects the VXL-3s from overheating.
  • Locked Rotor Protection prevents system damage by cutting power if the vehicle is stuck or the motor is bound.
  • Sensor Phase Detection protects against improperly wiring aftermarket sensored motors.
  • Sensored Motor Backup protection causes the VXL-3s to switch to sensorless operation if a motor sensor fails or sensor wires become disconnected. Sensored motors can be used without connecting the sensor wires to the sensor port on the ESC.
  • Battery Over-Voltage Protection causes the ESC to go into failsafe mode if the maximum input voltage is exceeded.
• Water resistent case design uses rubber seals and o-rings to protect against damage caused by water and moisture.
• Micro-fin aluminum heatsink dissipates heat.
• The built-in auxiliary fan output powers a snap-on accessory fan for increased cooling capacity during extreme use. A handy clasp on the speed control case keeps the wire neatly in place until you are ready to use it.
• MOSFET design provides high-current output (320 amp peak) with incredibly low resistance (.00075 Ohms).
• Gold plated 3.5mm bullet connectors on 12-gauge Maxx Cable flow full power to the motor without performance strangling resistance.
