Tamiya 41086 FR-32FX: Precision Cooling for Racing Builds

For serious radio control builders, the Tamiya 41086 FR-32FX Glow Engine with Aluminum Heat Sink Head blends thoughtful engineering with practical race-day benefits. Revealed at the Shizuoka Hobby Show, this upgrade attracts attention for balancing reduced weight with improved thermal management.

Reasons to Fit the FR-32FX

The FR-32FX stands out as a focused performance upgrade from Tamiya. Its blue aluminum heat sink head is more than cosmetic: it lowers component mass while moving heat away from critical areas, helping the engine hold steady temperatures during extended runs.

How the Heat Sink Helps Performance

The aluminum head's light construction cuts overall engine weight and speeds heat transfer. That combination supports consistent output across longer sessions and reduces thermal stress on internal parts, which is important for track reliability and tuning stability.

Fitment and Service Notes

Offered both as a separate heat sink head and as part of FR32-FX engine packages, the 41086 fits a range of setups. Check your model's mounting and head compatibility before purchase, and plan for routine cleaning to keep cooling fins clear of grime.

The Tamiya 41086 FR-32FX is a practical upgrade for racers and hobbyists wanting cooler running and a lighter head assembly without complex modifications.
