Optimise Power Delivery with the 3Racing 3RAC-PG6447

Serious hobbyists looking for dependable gearing will value the 3Racing 64 Pitch Pinion Gear 47T. Its 7075 aluminium construction and hard coating aim to preserve tooth profile under repeated use.

Alloy Strength for Repeated Use

The high-grade 7075 alloy gives improved strength for everyday running, while the hard coat helps resist scuffing and small surface wear that can affect mesh accuracy.

Precise 64 Pitch Engagement

The 47-tooth configuration on a 64 pitch is ideal for nuanced ratio changes, enabling fine tuning for different track layouts and motor setups.

Fits a Range of 1/10 Scale Setups

This pinion suits many 1/10 scale models that accept 64 pitch gears, making it a practical upgrade for both competitive and leisure use.

How do I set correct gear mesh with this pinion?

Fit the pinion while holding the spur in place, check for a small clearance using a business card method, then tighten the grub screw and recheck under load to confirm no binding.

Are there benefits over steel pinions?

7075 aluminium is lighter and can reduce rotating mass, while the hard coat narrows the durability gap to steel in many hobby applications, trading off extreme impact resistance for weight savings.

What tooth count changes should I try for different tracks?

Smaller pinion tooth counts favour acceleration and tighter tracks, while larger counts improve top speed. Try 1-2 tooth steps to assess differences without major drivetrain changes.

Is this pinion suitable for regular wet conditions?

The hard coat helps resist corrosion and wear, but water exposure still requires thorough drying and lubrication checks after running to prevent long term issues.
