This aluminium alloy motor heat sink is an aftermarket cooling accessory for Kyosho Mini Inferno ST motor bays. It increases exposed surface area around the motor to improve heat transfer and helps stabilise temperature during repeated runs and short races, making it suitable for hobby-grade electric RC use.
Installation is straightforward for experienced hobbyists: position the sink so it contacts the motor can while checking nearby wiring and ESC placement. Confirm there is adequate clearance around the motor and body before final mounting, as small adjustments or trimming of adjacent components may be needed depending on your setup.
As a passive thermal management aid the part reduces peak motor temperature to limit thermal-related power loss during sustained throttle. Use in combination with conservative gearing and proper ESC programming to maintain consistent performance across multiple runs.
