This aluminium alloy heat sink is an aftermarket part meant for Kyosho Mini Inferno ST motor setups. It increases exposed metal surface around the motor to assist heat dissipation and help keep temperatures more consistent during short races and club practice.
Installation is simple for experienced hobbyists: place the heat sink to touch the motor can while verifying that ESC leads and connectors are clear. Depending on body fitment and chassis layout a small amount of trimming or repositioning of components may be necessary for an interference-free mount.
As a passive accessory the heat sink lowers thermal stress on the motor, helping reduce temperature-related losses over back-to-back runs. Combine with proper ESC programming and conservative gearing to preserve performance and reliability.
