Frequently Asked Questions
- What is a pinion gear and why do I need to replace it? — A pinion gear is the small gear attached to your RC car's motor shaft that meshes with the larger spur gear to transmit power to the wheels. Pinion gears wear over time with use, and replacing a worn pinion is essential to maintain smooth drivetrain operation and prevent damage to other components. Additionally, changing your pinion gear size allows you to adjust your RC car's speed and acceleration characteristics.
- What does the 22T specification mean? — The 22T refers to the number of teeth on the pinion gear. This tooth count, combined with your spur gear's tooth count, determines your overall gear ratio. A 22-tooth pinion offers a balanced setup suitable for general driving, whilst lower tooth counts favour speed and higher counts favour acceleration and torque.
- What is the Safe-D8 bore and is it compatible with my ARRMA vehicle? — The Safe-D8 bore is ARRMA's proprietary motor shaft interface system. This pinion gear will only fit ARRMA vehicles equipped with Safe-D8 compatible motor shafts. If you're unsure whether your vehicle uses Safe-D8 shafts, please check your ARRMA vehicle's specifications or contact us for guidance on the correct pinion gear for your model.
- How does changing my pinion gear affect my RC car's performance? — Your pinion gear size directly influences your RC car's speed and acceleration. Using a pinion with fewer teeth increases your top speed but reduces acceleration and torque, whilst more teeth provides stronger acceleration at the expense of top speed. The 22T is a mid-range option that works well for most driving styles and conditions.
- Is this pinion gear suitable for beginners? — Yes, the ARRMA 22T Mod1 is suitable for beginners who already own a compatible ARRMA RC vehicle. If you're new to RC and purchasing your first vehicle, we recommend starting with a ready-to-run RC car UK that comes with all necessary components pre-installed. This pinion gear is ideal for maintenance and upgrades once you're familiar with your vehicle.
- How long do pinion gears last? — Pinion gear lifespan depends on driving intensity, surface conditions, and maintenance. Regular inspection and replacement of worn pinions is recommended to prevent damage to your spur gear and motor. Casual drivers may replace pinions annually, whilst competitive racers may need replacements more frequently.
