Overview
The Traxxas Heat Sink for the Velineon 380 brushless motor is an essential cooling upgrade for RC enthusiasts looking to maximise motor performance and extend run times. If you're running a brushless RC car, truck, or monster truck in the UK and want to keep temperatures down during intense bashing sessions, this blue-anodised aluminium heat sink is designed to do exactly that. The Velineon 380 is one of Traxxas's most popular brushless motors, found in numerous high-performance RC vehicles, and adding this dedicated cooling solution helps ensure consistent power delivery and motor longevity.
This high-quality aluminium heat sink works by dissipating excess thermal energy away from the motor windings, allowing your brushless system to maintain peak efficiency for longer without throttle-back or performance loss due to heat soak. Whether you're a competitive racer chasing lap times, a weekend basher pushing your RC car to its limits, or someone who simply wants to protect their investment, thermal management is crucial. The blue-anodised finish not only looks great on your RC model, but also provides a protective coating over the aluminium substrate, ensuring durability and corrosion resistance through countless charging cycles and outdoor sessions.
Traxxas is a globally recognised manufacturer of premium RC vehicles and components, and this genuine OEM heat sink comes with everything you need to install it properly, including thermal paste for optimal contact between the motor and sink. If you're using a Traxxas E-Revo VXL with brushless electronics or any other compatible 26-27mm diameter motor setup, this is a straightforward upgrade that delivers measurable results in terms of temperature reduction and consistent performance.
Key Features
- Blue-Anodised Aluminium Construction — The heat sink is manufactured from lightweight yet thermally conductive aluminium with a professional blue-anodised finish, which protects against corrosion and gives your RC car a polished appearance whilst providing excellent heat dissipation properties.
- Optimised for Velineon 380 Motors — Specifically designed and engineered by Traxxas to fit 26-27mm diameter brushless motors, ensuring perfect fitment and maximum thermal contact with the Velineon 380 and compatible motor sizes.
- Includes Thermal Paste — Traxxas supplies thermal paste with this heat sink, which is essential for establishing optimal thermal transfer between the motor case and the aluminium heat sink surface, ensuring you can install and start cooling immediately.
- Extended Run Times — By reducing motor operating temperature, this heat sink allows your brushless motor to run harder for longer without thermal throttling, delivering consistent acceleration and top speed throughout your entire battery pack.
- Improved Motor Longevity — Lower operating temperatures directly extend the lifespan of your brushless motor's internal components, including the stator windings and bearing assemblies, reducing wear and protecting your investment.
- Simple Installation — The heat sink is designed as a direct bolt-on upgrade for compatible Traxxas vehicles and other 26-27mm diameter motor setups, requiring no modifications to your RC car or electronics.
- Enhanced Performance Consistency — With active cooling management, you'll experience more predictable handling and acceleration characteristics throughout extended run sessions, as the motor maintains stable temperature and power delivery.
Technical Performance
The Traxxas Heat Sink for Velineon 380 brushless motors represents precision engineering applied to thermal management in RC applications. Manufactured from high-grade aluminium, the heat sink features a design optimised specifically for 26-27mm diameter motors, which includes the Velineon 380 brushless motors found in popular Traxxas ready-to-run RC vehicles such as the E-Revo VXL 1/16 scale 4x4 brushless monster truck in both purple and blue colour options. The blue-anodised surface finish provides dual benefits: aesthetic appeal that complements modern RC vehicle designs, and functional corrosion resistance that ensures longevity even in damp UK conditions. The aluminium construction offers superior thermal conductivity compared to plastic alternatives, actively pulling heat away from the motor case during operation. This is particularly important in high-performance brushless systems where sustained high-current draw can elevate motor temperatures significantly. The inclusion of thermal paste ensures that when installed, the heat sink establishes maximum thermal contact with the motor housing, eliminating air gaps that would compromise heat transfer efficiency. For UK RC enthusiasts running brushless systems, whether on 2S, 3S, or higher voltage LiPo battery packs, this cooling solution provides measurable performance benefits and is considered essential maintenance for serious RC car owners.

Frequently Asked Questions
- Will this heat sink fit my brushless RC motor? — This heat sink is designed for 26-27mm diameter brushless motors, including the Traxxas Velineon 380 and compatible motor sizes found in many modern RC cars and trucks. Before purchasing, verify that your motor falls within this diameter range to ensure proper fitment.
- What is thermal paste and why is it included? — Thermal paste is a conductive compound that fills microscopic imperfections between the motor case and heat sink surface, maximising thermal transfer efficiency. It's essential for optimal performance and Traxxas has thoughtfully included it with this product, so you can install and use the heat sink immediately without purchasing additional supplies.
- How much cooler will my brushless motor run? — The exact temperature reduction depends on ambient conditions, motor load, and battery voltage, but users can typically expect 10-20 degrees Celsius temperature drop under sustained high-performance running compared to running without a heat sink, particularly noticeable during extended bashing sessions.
- Is this suitable for beginners? — Yes, this is an excellent upgrade even for newcomers to RC hobbies. Installation is straightforward, and having proper cooling from the start protects your investment and ensures consistent performance. Any beginner running a brushless Traxxas vehicle will benefit from this cooling solution.
- Which Traxxas vehicles use this heat sink? — This heat sink is compatible with any Traxxas vehicle featuring a 26-27mm diameter brushless motor. Confirmed compatible models include the E-Revo VXL 1/16 scale 4x4 brushless monster truck in both purple and blue colour variants, though it will also fit other Traxxas and third-party vehicles with compatible motor dimensions.
- How do I install this heat sink? — Installation involves applying the included thermal paste to the motor case, then securing the aluminium heat sink using the appropriate fastening method for your specific vehicle. Consult your RC vehicle's instruction manual for detailed installation steps, as fitment specifics vary between models.
- Is the blue-anodised finish just aesthetic? — No, the blue-anodised aluminium finish serves both aesthetic and functional purposes. It protects the underlying aluminium from corrosion and oxidation, ensuring the heat sink maintains its thermal efficiency and appearance over months and years of use in UK weather conditions.
