This replacement heatsink is an RC-scale accessory designed for the Kyosho Mini Inferno speed control engine area, supplied as 3Racing MIF-020/OR/WO in an orange woven finish. It serves as a passive cooling aid for the electronic speed control (ESC) assembly, providing an additional heat-dissipating surface where the original part is compact or limited in airflow.
Compatibility is limited to the Mini Inferno family as indicated by the product name. Do not assume fitment with other Kyosho models or non-Kyosho chassis without verification of mounting points and clearances.
Installation is straightforward for users comfortable with basic chassis disassembly: remove the body and any obstructing components to access the ESC area, use the existing mounting points or screws on the ESC housing, and align the heatsink so it does not contact wiring or moving parts. Tighten fasteners to secure the part without over-stressing plastic mounts.
Tuning role: the heatsink increases surface area and can help lower operating temperature of the ESC under sustained load, which assists in more consistent power delivery during trimming and short track sessions. It is a passive modification and should be combined with sensible motor/ESC setup and proper airflow management for best results.
Care and maintenance: check clearance after installation, ensure wiring remains routed away from the heatsink, and periodically remove dust or debris that can reduce thermal effectiveness.
