About this item

  • Engineered specifically for 42mm diameter brushless motors—including the widely used 4268 and 4274 models—this silver aluminum heat sink delivers precision thermal management for high-performance 1/8 and 1/10 scale RC vehicles from Traxxas, Arrma, and other top brands.
  • Equipped with a smart thermal sensor and a whisper-quiet 40mm fan, it activates cooling only when motor temperature reaches 45°C (113°F), maximizing battery efficiency while preventing overheating during aggressive driving or extended runs.
  • The fan draws power directly from your receiver, eliminating the need for extra wiring, external controllers, or ESC taps—making installation clean, plug-and-play, and ideal for both garage builders and competition racers.
  • Machined from high-conductivity aluminum with a secure clamp design, it ensures full surface contact with the motor can for rapid heat transfer, reducing operating temperatures and significantly extending motor and ESC lifespan.
  • Whether you’re racing on asphalt, bashing through mud, or tackling steep climbs in summer heat, this intelligent cooling system keeps your powertrain running cooler and longer—so you spend less time waiting and more time driving.

    I found the replacement parts I needed for my RC truck without having to search through unrelated products. The categories were easy to understand, and the new wheels and suspension parts worked well for my weekend build.

    TinyRacer has a practical selection of RC tools, batteries, and upgrade parts. I picked up several items for maintaining my crawler, and everything made my workbench setup feel much more organized.

    I am still fairly new to RC cars, so I appreciated how clearly the products were grouped. It was easy to compare chargers, connectors, and maintenance supplies for my first off-road vehicle.
