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

Compact heatsink overview for Mini Inferno ESCs

This aluminium heatsink is made to fit the Kyosho Mini Inferno speed control area and improves heat dispersion from the ESC. The purple SSG finish identifies the MIF-020/PU/SG variant so you can spot it quickly during maintenance or parts swaps.

Fitment is straightforward: the component attaches around the speed control housing used on Mini Inferno kits and expands the exposed surface to shed heat more effectively. That added surface area helps limit temperature rise when the ESC is under sustained load, improving steadier performance during longer runs.

Installation pointers cover alignment and clearance checks. Make sure the heatsink slides over the speed control without touching drive gears, motor leads, or chassis elements. Confirm original screw bosses and mounting points remain usable so you can rely on the stock fasteners. If bodywork is tight, verify clearance around mounts and steering linkages before final assembly.

Performance role: this is a passive thermal aid rather than an electronic upgrade. Use it alongside sensible ESC programming and correct motor choice when addressing thermal cutback or aiming for more consistent runs in practice and club events.
