Kyosho Mini Inferno ESC Heatsink by 3Racing MIF-020/GR/WO  [MIF-020/GR/WO]

Speed control heatsink overview

This 3Racing MIF-020/GR/WO is a compact heatsink intended for Kyosho Mini Inferno speed control units in RC use. It is a scale accessory designed to increase the exposed cooling surface on the electronic speed control to help manage operating temperatures during short practice sessions and club runs.

The part mounts to the speed control assembly on compatible Mini Inferno setups and provides passive cooling through added surface area and fin geometry. The green finish identifies the part and helps with quick parts selection at the bench without changing the ESC’s internal layout.

Installation is straightforward: align the heatsink over the speed control body, check for clearance with nearby components, and secure it using the existing mounting points or compatible screws. After fitting, verify that airflow is not blocked by bodywork or accessories and that servo and receiver leads remain clear.

In tuning terms, this heatsink is a preventative fitment rather than a tuning item: it does not alter power delivery or electronics settings, but by helping to control temperature rise it can reduce thermal throttling risk during repeated runs and preserve consistent ESC performance across heats.
