Key Features

• Fully Waterproof Construction — The water-resistant case design uses rubber seals and o-rings to protect against damage caused by water and moisture, meaning you can confidently use your ready to run RC car in wet weather conditions or splash through water without fear of electrical damage.
• Patented Training Mode — This exclusive Traxxas feature reduces the overall power output of the VXL-3s by 50%, making it significantly easier for new or younger drivers to control their RC model. When drivers are ready to progress, simply switch profiles to unleash full-throttle action and unlock the complete performance potential.
• Three Programmable Drive Profiles — Switch between Sport Mode (forward, brake and reverse), Race Mode (forward and brake), and Training Mode (50% forward, brake and 50% reverse) depending on your skill level and driving conditions, giving you flexibility across different scenarios and experience levels.
• Two-Stage Low Voltage Detection — Built-in two-stage low voltage detection specifically designed for Lithium Polymer battery use provides a clear signal to the driver that the battery pack is nearing its minimum voltage threshold, protecting your expensive LiPo battery from over-discharge damage.
• Patented High-Current Connector — Traxxas' exclusive high-current connector eliminates common bottlenecks and maintains pure, unrestricted power flow from your battery to the brushless power system, ensuring absolutely no performance strangling caused by connector resistance.
• EZ-Set Push-Button Programming — The simple one-button setup operates and programs just like other Traxxas speed controls such as the XL-5, eliminating the need to learn tricky new procedures and getting you on the track or trail faster.
• Multi-Colour LED Feedback — Clear visual feedback through multi-colour LED indication lets you instantly understand the ESC status without needing to access a computer or programming device.
• Locked Rotor Protection — This intelligent safety feature prevents system damage by cutting power if your vehicle becomes stuck or the motor is bound, protecting your ESC and motor from catastrophic failure.
• Battery Over-Voltage Protection — The ESC automatically goes into failsafe mode if the maximum input voltage is exceeded, protecting your electronics from damage caused by overly powerful battery packs or charging errors.
• Dual-Stage Thermal Shutdown — Two-stage thermal shutdown protection safeguards the VXL-3s from overheating during extended use or in hot weather conditions, automatically throttling back power when temperatures approach critical levels.
• High-Current MOSFET Design — The advanced MOSFET design provides a peak output of 320 amps with incredibly low resistance of just 0.00075 ohms, delivering maximum power efficiency and minimal voltage drop to your brushless motor.
• Gold-Plated Bullet Connectors — Gold-plated 3.5mm bullet connectors on 12-gauge Maxx Cable flow full power to the motor without performance-strangling resistance, ensuring pristine power delivery from battery to motor.
• Micro-Fin Aluminium Heatsink — The precision-engineered micro-fin aluminium heatsink efficiently dissipates heat during intense driving sessions, keeping your ESC running cool even under demanding conditions.
• Auxiliary Fan Output — A built-in auxiliary fan output powers a snap-on accessory fan for increased cooling capacity during extreme use, allowing you to keep the VXL-3s at optimal operating temperatures during competitive racing or aggressive driving.
• Cable Management Clasp — A handy clasp on the speed control case keeps wires neatly organised and in place until you're ready to use the ESC, preventing tangling and damage during storage and transport.

Technical Performance

The Velineon VXL-3s represents the pinnacle of waterproof brushless ESC engineering for RC vehicles across the UK market. With a power rating exceeding 150 amps and peak current output of 320 amps, this speed control delivers extraordinary performance capabilities for brushless motor systems. The incredibly low MOSFET resistance of 0.00075 ohms ensures virtually no energy loss during power delivery, allowing your brushless motor to receive maximum current with minimal heating. The ESC accepts the widest range of battery options, from traditional 4-cell NiMH packs running at 10.8 volts up to powerful 3S LiPo battery packs delivering 11.1 volts, giving you complete flexibility in choosing your power source based on your RC car's performance requirements and your budget. The brushless technology itself provides superior efficiency compared to brushed alternatives, delivering more runtime from the same battery whilst generating less heat and requiring virtually no maintenance. The waterproof case design protects internal electronics with rubber seals and o-rings, whilst the micro-fin aluminium heatsink manages thermal output effectively. This speed control works with sensorless brushless motors and features multi-profile programmable operation, allowing you to adapt the ESC behaviour to match different driving conditions, skill levels or track requirements.
