Technical Performance
The ARRMA Spur Gear 63T MOD 0.5 represents precision engineering at its finest, designed specifically for the demands of 1/16 scale RC racing and bashing. The metal construction provides the hardness and wear resistance necessary for countless hours of operation, whether you're experiencing the explosive acceleration of a 3S LiPo-powered brushless system or executing high-speed cornering manoeuvres on mixed terrain. The MOD 0.5 tooth profile is a critically important specification — this modulus designation determines tooth size and spacing, ensuring that meshing with your vehicle's pinion gear occurs with minimal backlash and maximum efficiency. When precision-engineered components like this spur gear work together with ARRMA's brushless motor and ESC setup, you get smooth power delivery, reduced drivetrain noise, and extended component lifespan. The 63-tooth count establishes the gear ratio that balances the Mini Kraton 3S's performance characteristics, allowing the brushless motor to deliver its full power potential while maintaining suitable speeds for both on-road and off-road driving styles. This component is the result of ARRMA's experience building ready to run RC models that deliver exceptional performance and reliability, making it an investment that pays dividends through improved durability and consistent performance.
