For racers tuning Kyosho Mini Inferno cars, the 3Racing MIF-020/PU/WO woven purple heatsink is a compact thermal management part intended to lower local temperatures on the speed control engine during back to back runs.
Use this heatsink as part of a race day cooling plan; it complements setup choices such as timing, gearing and airflow management to help maintain consistent electronics temperatures.
Install the heatsink so it maintains direct contact with the engine block and verify retention after initial track use. Consider routine checks between heats to ensure mounting hardware remains secure under vibration and heat cycles.
