Keep nitro temps down with the XRAY 611601 heatsink

Serious hobbyists running NT18 engines can benefit from the XRAY 611601 CNC-machined aluminum heatsink. It delivers targeted cooling and a robust blue anodized finish that stands up to frequent track use.

Maintaining steady engine temperatures

Controlling head temperature helps preserve performance and reduces component stress. The XRAY 611601 uses aluminium's efficient heat transfer to move thermal energy away from the combustion area, helping the engine maintain dependable output.

Precision machining meets rugged finish

CNC machining ensures a snug fit and maximises surface area for cooling while keeping weight low. The anodized blue coating adds a layer of protection against corrosion and minor impacts from everyday handling.

Will this reduce engine tuning needs?

It can help stabilize temperature-related tuning drift, but you should still tune needle settings based on running conditions and fuel.

Can the heatsink be milled for extra airflow?

Modifying a machined heatsink is possible but not recommended unless you have precision tools; changes can affect fit and thermal performance.

Are replacement screws available separately?

If screws are lost, standard small machine screws of the same thread and length can be used; check dimensions before substituting.

Does it add noticeable weight?

The heatsink is machined to balance strength and lightness; you will see minimal weight gain while gaining better heat dispersion.
