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

Overview of ESC cooling for Mini Inferno

This heatsink is an accessory for the Kyosho Mini Inferno speed control area, intended to improve heat dispersion from the ESC assembly. The purple SSG finish denotes the MIF-020/PU/SG variation so you can spot it quickly when swapping parts in the pit box.

The part increases metal surface area around the speed control, which helps reduce temperature rise under sustained load. That extra cooling capacity supports more consistent ESC output during longer practice sessions or when running repeated bursts.

Installation advice centres on checking alignment and avoiding interference. Confirm the heatsink clears gears, motor wiring, and chassis brackets, and that existing screw bosses remain accessible so stock fasteners can be used. If your bodywork sits close to the chassis, double-check clearance with mounts and steering linkages before securing the part.

Remember this is a passive thermal aid and not an electronic upgrade. Pair it with correct ESC setup and motor selection when tackling thermal issues or trying to improve mid-run stability.
