Savage 13-Fin Titanium Cooling Fin Heatsink HSA-027/TI by 3Racing  [HSA-027/TI]

Scale cooling fin for Savage trucks

This RC heatsink is built for Savage model compatibility and carries the identifier HSA-027/TI. Its 13-fin layout and titanium surface give concentrated cooling area tailored to small nitro heads fitted to off-road trucks.

The device works by enlarging the head's exposed surface so heat can dissipate more readily, which supports more consistent engine temperatures during long runs or when adjusting settings. It is intended for model use and not for any full-scale engine.

Mounting guidance: attach the heatsink to the engine head using the vehicle's original head mount points and hardware. Confirm there is enough clearance beneath the chassis and that the fins align with airflow paths before locking it down. No extra hardware is assumed to be included.

Practical effect on tuning: fitted correctly the heatsink helps control peak temperature swings and can ease achieving a stable idle while testing mixtures or needle positions. It is a thermal management upgrade rather than a performance booster.
