High Density Fin Design for FS12S

This blue anodized aluminum head is engineered for FS12S size engines and uses a high density fin pattern to enhance convection. By packing in over three times the fins and raising surface area by more than 1.5 times, it reduces heat soak during long runs.

Designed for Shallow Body Shells

The heat sink's slim profile allows it to fit under shallow-bodied RC cars such as the Ferrari F430 without body alterations. That makes it a sensible choice when you need extra cooling but want to keep the original shell fitment.

Will this fit my FS12S without head modification?

It mounts using the included gasket and screws and is compatible with common FS-12 series heads. No special machining should be required for standard engines.

Can I run this on both on-road and off-road models?

Yes, the sink improves heat dissipation across different running surfaces, though actual benefit varies with airflow and how the model is driven.

Does the anodized finish affect heat transfer?

The blue anodize gives corrosion resistance and can withstand handling; the core aluminum still provides the thermal conductivity needed for effective cooling.
