Kyosho Mini Inferno Speed Control Heatsink by 3Racing MIF-020/PU/SG  [MIF-020/PU/SG]

Mini Inferno speed control heatsink overview

This heatsink is an RC-scale accessory intended for the Kyosho Mini Inferno line, serving a single purpose: improve heat dissipation from the speed control assembly. The purple SSG finish identifies this MIF-020/PU/SG variant and helps distinguish it when servicing or swapping components in the pit box.

Fit and function are straightforward: the part mounts to the speed control housing area used on Mini Inferno models and increases exposed surface area to shed heat. That change in surface area reduces temperature rise under load, which can help maintain consistent ESC behavior during longer runs or repeated high-power bursts.

Installation notes focus on alignment and clearance. Confirm the heatsink fits over the existing speed control body without contacting gears, motor wires, or the chassis. Verify that any original screw bosses or mounting points remain accessible so the stock fasteners can secure the assembly. If the vehicle has tight bodywork, check clearance with body mounts and steering linkages before finalising fitment.

Tuning role: this accessory is a passive thermal aid rather than an electronic upgrade. Use it as part of a thermal-management approach when you are troubleshooting thermal cutback or aiming for more stable performance over extended practice or race sessions. It complements, but does not replace, correct ESC programming and motor selection.
