Team Corally has engineered this component using special steel and advanced manufacturing techniques to ensure every tooth is perfectly shaped with unparalleled concentricity, making it an essential upgrade or replacement part for RC car UK users looking to maintain peak performance.

This 15-tooth pinion is manufactured to exacting standards that set it apart from budget alternatives. The special hardened steel construction means the gear can withstand the demands of high-power brushless motors without premature wear or tooth stripping, a common issue when using inferior materials. The pinion's ultra-precise tooth shaping ensures smooth meshing with your spur gear, reducing vibration that can affect handling and speed consistency. For RC enthusiasts building a ready to run RC setup or upgrading an existing machine, having quality drivetrain components like this pinion is essential to achieving reliable performance and longevity.

Every Corally pinion is clearly marked with its tooth number for easy and quick identification, making it simple to manage multiple pinions for different gear ratio setups. This is particularly useful if you're experimenting with different ratios for various track conditions or switching between speed and torque configurations. Available in all gearing sizes within the 32 DP range, this 15T pinion allows you to find the perfect gear ratio for any track, whether you're racing tight technical courses or open-plan speed runs. The 5.0mm motor shaft diameter makes this compatible with standard RC motors across numerous popular platforms.

Key Features

• Special Hardened Steel Construction — The pinion gear is manufactured from special hardened steel, providing exceptional toughness and durability that resists tooth wear, stripping, and deformation even under high-power brushless motor stress. This material choice means your investment will last longer than softer brass alternatives, maintaining performance consistency throughout the life of the component.
• CNC Cut Teeth for Perfect Geometry — Every tooth on this pinion is shaped using CNC cutting technology, ensuring perfect tooth profile and concentricity. This precision manufacturing eliminates the inconsistencies found in cheaper stamped or cast gears, resulting in smooth meshing and reduced noise during operation.
• Ultra-True Running for Vibration-Free Operation — The combination of precise tolerances and perfect concentricity means this pinion runs with minimal runout, delivering vibration-free operation. This is critical for maintaining handling consistency and preventing premature wear on adjacent drivetrain components like spur gears and bearings.
• 32 DP Gear Pitch Standard — The 32 DP specification ensures compatibility with the vast majority of modern RC car gearboxes and spur gears, making this a genuinely universal replacement that works across multiple brands and models in the RC car UK market.
• 15 Teeth for Optimised Gearing — The 15-tooth configuration provides a popular gear ratio choice that balances acceleration and top speed. Combined with your spur gear selection, this pinion allows you to fine-tune your RC car's performance characteristics for specific track conditions.
• 5.0mm Motor Shaft Diameter — The pinion is engineered for 5.0mm motor shafts, the industry-standard size for most modern brushless and brushed RC motors. This ensures a secure fit without wobbling or slipping under power delivery.
• Easy Identification Marking — Each pinion is permanently marked with its tooth number, eliminating confusion when managing multiple pinions in your RC toolkit. This is invaluable when switching between different gear ratios or helping you quickly identify the correct pinion for replacement.
• Made in Europe — Manufactured to European engineering standards, this pinion benefits from quality control and precision that reflects Team Corally's commitment to producing premium RC components.

Technical Performance

The Corally C-72515 pinion gear represents a significant step up in drivetrain quality for any RC car UK user serious about performance and longevity. The special hardened steel material undergoes a rigorous hardening process that increases surface hardness whilst maintaining toughness, preventing both brittle fracture and wear. The CNC cutting process creates teeth with precise involute profiles, which is the mathematically optimal shape for smooth power transmission and minimal noise. When meshing with a compatible spur gear, the ultra-true running characteristic of this pinion — achieved through tight tolerances and precise concentricity — ensures that rotational forces transfer smoothly from your motor to the drivetrain without the vibration and noise associated with inferior gears. The 32 DP pitch, combined with the 15-tooth count and 5.0mm bore, makes this pinion suitable for a wide range of RC vehicles including buggies, trucks, and touring cars running standard brushless motors in the 3500-4000 KV range. The 6.20mm teeth width and 13.00mm gear length provide robust engagement with typical spur gears, whilst the 2.0mm hex key size allows easy installation and removal using standard RC tools. Whether you're running a competitive race car, a high-powered basher, or upgrading a ready to run RC vehicle, this pinion will deliver the performance and reliability expected from Team Corally's premium component range.

Frequently Asked Questions

• What is a 32 DP pinion gear and why does the pitch specification matter? — DP (Diametral Pitch) is a standard measurement used to specify gear sizes and tooth spacing. 32 DP is one of the most common standards in RC cars, ensuring this pinion is compatible with a vast selection of RC vehicles and spur gears from multiple manufacturers. The pitch specification ensures proper meshing and prevents binding or excessive play in your drivetrain.
• Is the Corally 15T pinion suitable for high-powered brushless RC cars? — Yes, absolutely. The special hardened steel construction makes this pinion ideal for high-power brushless motors. The hardened steel resists tooth stripping and deformation that can occur with softer brass gears when subjected to the high torque output of modern brushless systems. This pinion is specifically engineered to handle the demands of competitive RC racing and high-performance bashing.
• What is the difference between this hardened steel pinion and cheaper brass alternatives? — Hardened steel is significantly harder and more durable than brass, meaning it resists wear much more effectively. Brass gears will eventually develop flat spots on the tooth faces as they wear, reducing mesh quality and introducing noise and vibration. This steel pinion, with its special hardening process, maintains its tooth profile throughout its lifespan, delivering consistent performance and reliability. The precision CNC cutting also ensures these hardened teeth maintain perfect geometry where softer materials might distort.
• Will this pinion fit my RC car? — This pinion is designed for any RC car with a 32 DP gearbox and a 5.0mm motor shaft. This is the industry standard for most modern brushless RC cars, buggies, trucks, and touring cars. If your car uses a standard brushless motor and a 32 DP spur gear, this pinion will fit. If you're unsure about your car's specifications, check your motor shaft diameter and gearbox pitch — both should be clearly marked on your vehicle's documentation.
• How do I identify which pinion tooth count I need? — Pinion tooth count selection depends on your desired gear ratio, which combines the pinion teeth count with your spur gear tooth count. A lower tooth pinion (like 15T) provides more top speed but lower acceleration, whilst a higher tooth pinion provides more acceleration but lower top speed. Your choice depends on whether you're optimising for speed runs or technical courses. The clear marking on each Corally pinion makes it easy to identify which ratio you're using.
• Is this pinion suitable for beginners? — Yes, this pinion is suitable for users of all skill levels. Whether you're a beginner just getting started with RC cars or a seasoned racer, quality drivetrain components ensure reliable, trouble-free operation. This pinion is actually an excellent choice for beginners because its durability means fewer breakdowns and more time enjoying your RC car.
• What tools do I need to install this pinion? — The Corally pinion uses a 2.0mm hex key (socket) for installation, which is a standard tool found in most RC tool kits. Installation is straightforward — simply remove your old pinion and install this one using the hex key to tighten the set screw. No specialised tools or technical expertise is required.
