Mini Inferno Competition ESC Heatsink MIF-020/PU/SG by 3Racing  [MIF-020/PU/SG]

Competition-grade cooling overview

Engineered for the Kyosho Mini Inferno speed control area, this heatsink increases exposed metal surface to reduce ESC temperature rise during repeated high-power runs. The purple SSG finish denotes the MIF-020/PU/SG variant for quick identification in a race spares kit.

Its passive cooling effect helps preserve consistent ESC output during extended sessions by improving thermal transfer away from the speed control body. While not an electrical modification, it is a useful element in a race-focused thermal-management strategy.

Fitment requires validating alignment and clearance: ensure no contact with gears, motor wiring, or chassis mounts and confirm original screw bosses are accessible for secure fastening. Check full range steering and body clearance as part of final setup to avoid on-track failures.

Use this heatsink alongside correct ESC calibration, appropriate motor selection and track-appropriate gearing to achieve the best sustained performance in competitive environments.
