ESC heatsink summary

The MIF-020/GR/WO is a compact green heatsink made for Kyosho Mini Inferno speed control units, increasing exposed surface area to help manage temperatures during short practice runs and club racing.

The heatsink mounts to the ESC housing on compatible Mini Inferno setups and uses fin geometry to provide passive cooling. Its green finish helps with quick part identification on the bench while leaving the ESC internals unchanged.

Fitting is simple: position the heatsink over the ESC body, confirm clearance from nearby parts, and attach using the existing mounting points or suitable screws. After installation, check that bodywork does not block airflow and that servo and receiver leads remain free.

This item is a preventative cooling upgrade rather than a tuning change: it will not affect power delivery or electronic settings, but by limiting temperature rise it can help maintain consistent ESC performance through multiple heats.
