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

What this heatsink does

The MIF-020/GR/WO is a compact cooling fin crafted for Kyosho Mini Inferno ESC housings to enlarge the exposed surface area and help control operating temperatures during short race sessions.

The heatsink secures to the speed control casing on compatible Mini Inferno setups and relies on fin layout to provide passive cooling. The green finish makes it quick to spot on the bench without disturbing the ESC internals.

To fit, centre the heatsink over the ESC body, check clearance from nearby components, and fasten using the ESC mounting points or appropriate screws. After fitment, ensure bodywork does not impede airflow and that cabling is routed clear of the fins.

This is a reliability-focused accessory rather than a tuning part: it will not change power characteristics but can reduce the chance of thermal limiting during repeated heats.
