Customer Questions & Answers

  • Question: What is the difference between the 15T, 16T, 17T, 18T, and 19T pinion gears in this set?

    Answer: The pinion gears 15T, 16T, 17T, 18T, and 19T indicate the number of teeth on each gear. Fewer teeth, like on the 15T gear, usually result in higher speed but lower torque, making it suitable for fast applications. Conversely, more teeth, as in the 19T gear, provide higher torque but slightly lower speed. This variability allows users to customize their RC vehicle's performance based on the desired balance of speed and power. It's ideal for racers seeking speed or rock crawlers needing torque.
  • Question: Are these pinion gears compatible with other types of RC motors?

    Answer: While this gear set is specifically designed for brushless RC motors, it may also fit some brushed motors depending on the shaft size. The critical factor is the 3.175mm hole (1/8 inch) compatibility with the motor shaft. Users should always double-check the specifications of their motor before purchase. This versatility allows hobbyists with different motor types to upgrade their setups without an entirely new gear set.
  • Question: What material are these pinion gears made from?

    Answer: These pinion gears are crafted from hardened steel, which offers superior strength and durability compared to standard materials. Hardened steel is resistant to wear and deformation, making it ideal for high-performance applications in RC cars. As a result, these gears can withstand demanding driving conditions, including high-speed racing and rough terrain, enhancing the overall longevity and reliability of your RC vehicle.
  • Question: How do I install the pinion gears on my RC motor?

    Answer: Installation of the pinion gears involves removing the existing gear from the motor shaft and then fitting the new gear aligned properly. Use the included hex key to securely tighten the gear on the shaft, ensuring it's not loose during operation which could lead to slippage. Proper installation is crucial for optimal performance, as a well-fitted gear will enhance overall efficiency and prevent unnecessary strain on the motor, thus prolonging its life.
  • Question: Can I use these pinion gears for custom RC builds?

    Answer: Absolutely! This set is ideal for custom RC builds due to its versatile sizes and durable construction. Hobbyists can mix and match the pinions to achieve a tailored performance for specific environments, whether it’s racing on track or crawling over rugged terrain. The 15T to 19T options allow for individualized speed and torque settings based on the requirements of your custom build, giving you the freedom to experiment.
  • Question: What is the significance of the hex key included in the set?

    Answer: The hex key included is essential for properly installing and tightening the pinion gears onto the motor shaft. Using the hex key ensures a snug fit, preventing slippage during operation. A secure connection is vital for maintaining performance, as loose gears can result in inefficient power transfer and damage to the motor. The inclusion of this tool simplifies the setup process, making modifications easier and more efficient for RC enthusiasts.
  • Question: Will these gears fit on a standard RC car?

    Answer: These gears are generally compatible with most RC cars that utilize a 3.175mm shaft. However, it’s important to confirm the compatibility by checking the specifications of your RC car's motor is before making a purchase. The ability to use these gears can significantly improve your car's performance, making them a great enhancement for racers and casual users alike who want to upgrade their vehicle's capabilities.
  • Question: What benefits does a hardened steel pinion gear offer over other materials?

    Answer: Hardened steel pinion gears offer distinct advantages such as increased wear resistance and better performance under stress compared to softer materials like aluminum or plastic. They do not deform easily under high torque loads, ensuring they maintain their shape even during intense maneuvers. This durability makes them suitable for both competitive racing and rugged terrains, providing peace of mind for users subjecting their RC cars to harsher conditions.
  • Question: Can I buy individual gears from this set?

    Answer: This product is designed as a complete set, and individual gears are not typically sold separately. The variety provided in this package—from 15T to 19T—offers the convenience of having multiple options at your disposal without needing to source each gear individually. This set caters to enthusiasts who may want to experiment with different gear ratios to optimize their RC vehicle performance effectively.
  • Question: Where can I buy the 0.8M Hardened Steel Pinion Gear Set in Suriname?

    Answer: You can purchase the 0.8M Hardened Steel Pinion Gear Set with a hex key for RC brushless motors from Ubuy in Suriname. Ubuy offers a convenient online shopping experience and ensures that you have access to quality products tailored for your needs.
