XRAY 611601 Blue-Anodized CNC Heatsink Head with Shim  [XR-611601]

Performance cooling from the XRAY 611601 heatsink

For modelers focused on consistent engine performance, the XRAY 611601 CNC-machined aluminum heatsink is a practical upgrade. Engineered for the NT18, it adds real cooling capability while dressing up the engine with a blue anodized surface.

Why cooling matters for nitro setups

Nitro engines need effective heat control to avoid detonation and wear. The XRAY 611601 uses high-grade aluminum to move heat away from the head quickly, helping keep combustion stable and component temperatures lower during long runs.

CNC precision and a protective anodized coat

CNC machining produces accurate tolerances and a compact form that increases exposed area for heat shedding. The blue anodize offers resistance to scratches and oxidation that come from regular track use.

Used as part of a maintenance or upgrade plan, the XRAY 611601 is a straightforward way to manage heat and keep NT18 engines running smoothly.
