FX Engines Product Range

FX builds nitro engines for serious RC racers across all popular racing classes. Their lineup is straightforward:

• K303 and K502 engines for 1/8 buggy and truggy racing
• T300 for 1/10 on-road competition
• K301 EC as a solid entry point for newer racers. 

You'll find 2-port, 3-port, and linear port designs letting you match power delivery to your driving style.

The parts selection reduces the unnecessary and focuses on what actually makes your car faster. This includes crankshafts with precise tungsten weights (77-82g) for smoother idling between 4,000-6,000 RPM, specialized cooling heads that keep operating temperatures between 107-121°C, and race-legal exhaust systems that work with your engine type, from running 2.1cc touring cars (21,000-42,000 RPM) to 3.5cc off-road applications (18,000-35,000 RPM).

Why FX Engines

FX’s advantage comes from actual technical differences in how the engines are built. The diamond-like coating (DLC) they apply to crucial moving parts reduces friction tremendously compared to standard finishes, meaning your engine maintains power longer during race day. The ceramic bearings handle temperatures up to 40°C higher than steel bearings before failing.

The precision balancing on every rotating assembly means your car isn't wasting power through vibration, giving you more consistent lap times in the 2-5 second range. Finnish engineering culture shows in the details. This ranges from the exact port timing (measured in actual degrees rather than vague "performance" claims) to the sealed combustion chambers that maintain compression between 8:1 and 9.5:1, depending on fuel type.
