- Q: What material are the pinion gears made of? A: The pinion gears are made of hardened steel. This material ensures durability and reusability for various RC applications.
- Q: What is the tooth pitch of these pinion gears? A: The tooth pitch is thirty-two pitch, equivalent to zero point eight module. This specification allows compatibility with various spur gears.
- Q: What sizes do the pinion gears come in? A: The pinion gears come in five sizes: thirteen teeth, fourteen teeth, fifteen teeth, sixteen teeth, and seventeen teeth. This variety allows for different gear setups.
- Q: How do I install the pinion gears? A: Installing the pinion gears is straightforward. Simply attach them to the motor shaft using the included grub screws, ensuring a secure fit.
- Q: Are these pinion gears suitable for my RC car? A: Yes, these pinion gears are compatible with various RC cars including Arrma, Traxxas, Axial, HSP, and Losi models. Make sure your motor has a five millimeter shaft.
- Q: How can I ensure the gears mesh properly? A: To ensure proper meshing, verify that the spur gear and pinion gear have the same pitch. This prevents gear teeth from misaligning.
- Q: What should I do to maintain my pinion gears? A: To maintain the pinion gears, regularly check the temperatures of the motor and ESC to prevent overheating. This helps ensure optimal performance.
- Q: Can I use these gears in a one-tenth scale RC car? A: Yes, these pinion gears are designed for both one-eighth and one-tenth scale RC cars. They fit motors with a five millimeter shaft.
- Q: How do I store the pinion gears? A: Store the pinion gears in a dry place away from moisture. Keeping them in their original packaging can help prevent damage and tangling.
- Q: What if the pinion gears arrive damaged? A: If the pinion gears arrive damaged, contact customer support immediately for assistance with returns or replacements. It’s important to address issues promptly.
- Q: Are these pinion gears easy to upgrade? A: Yes, these pinion gears are easy to upgrade. Simply replace the existing gears with the new ones to enhance your RC vehicle's performance.
- Q: Is there a warranty on these pinion gears? A: Yes, these pinion gears typically come with a manufacturer warranty. Check the packaging or product details for specific warranty information.
- Q: Do I need special tools to install these pinion gears? A: No, you do not need special tools. A standard hex wrench is sufficient to tighten the grub screws for installation.
- Q: Can I mix different tooth sizes for racing? A: Yes, mixing different tooth sizes can optimize your gear setup for specific racing conditions. Adjust according to your track requirements.
- Q: What is the height of the pinion gears? A: The height of the pinion gears is fourteen millimeters. This measurement is standard for compatibility with various motor setups.
