Frequently Asked Questions
- What is a Safe-D5 bore and why does it matter for my RC car UK? — The Safe-D5 bore features a distinctive D-shaped hole that matches the profile of your motor shaft perfectly. This design is crucial because it prevents your drive and braking power from being lost if the set-screw backing out, a common problem in high-performance RC vehicles. This safety feature has become the recognised standard in the brushless RC hobby, particularly for vehicles operating at 6S voltage levels.
- Which ARRMA RC vehicles is this pinion gear compatible with? — The ARRMA 17T Mod1 Safe-D5 Pinion Gear is compatible with several popular ARRMA 6S brushless RC models, including the Felony 6S BLX (both Orange and Black versions), the 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck, the 1/7 TALION 6S EXB 4X4 RTR Speed Truck in Black, and the Typhon 6S V5 BLX. Always verify your specific model before ordering to ensure compatibility.
- Is this a replacement part or an upgrade? — This is a genuine OEM replacement pinion gear that matches the specifications of the original component fitted to ARRMA 6S brushless vehicles. It can be used as a direct replacement if your current gear is worn or damaged, or as an upgrade if you're building a new vehicle or restoring an older model to factory specification.
- What does Mod1 pitch mean? — Mod1 (Module 1) refers to the pitch of the gear teeth, which determines how the pinion engages with your spur gear. Mod1 is a standard pitch used across the RC hobby and ensures proper meshing with compatible spur gears. Using the correct pitch is essential for smooth operation and durability.
- Do I need any tools to install this pinion gear? — Installation requires a small hex key or Allen wrench to tighten the M4 x 4mm set-screw, which most RC enthusiasts already have in their tool kit. The e-clip included provides additional security and is simple to install by hand.
- How often should I replace my pinion gear? — The lifespan of your pinion gear depends on how frequently you run your RC vehicle and the driving conditions. Steel gears like this one are extremely durable and should last for hundreds of driving sessions with proper maintenance. Inspect it regularly for wear, and replace it if you notice damaged or worn teeth affecting performance.
