Frequently Asked Questions

• What is a starting wheel and why do I need one for my nitro RC car? — A starting wheel is a rubber-faced component mounted on your mechanical starter box that engages with your nitro engine's flywheel to spin the engine for starting. The rubber grip ensures the wheel doesn't slip against the flywheel, transferring maximum torque from the starter box to your engine. Without a quality starting wheel in good condition, you'll experience slipping, inconsistent starts, and frustrating pulling failures—exactly what you want to avoid when you're ready to drive.
• How often should I replace my starter wheel? — The frequency of replacement depends on how often you use your nitro RC car and how well you maintain your starter box system. Over time, the rubber on the wheel wears and becomes glazed or shiny, which reduces grip and causes slipping during starting. If you notice your engine is harder to start, requires more pulls, or the starter wheel is visibly worn, it's time for a replacement. Having a spare starter wheel on hand is always a wise decision for regular nitro operators.
• Will this starter wheel fit my existing starter box? — The Fastrax Tru-Start Rubber Wheel features a 25mm centre hole designed for standard starter box shafts, and the eight 8x8mm outer mounting holes provide secure attachment to most common starter box systems. However, if you have a non-standard or specialised starter box, we recommend confirming compatibility before purchase. If you're unsure, our team at RC Model Shop is happy to help verify fitment for your specific setup.
• Is the Fastrax Tru-Start Rubber Wheel suitable for beginners to nitro RC? — Absolutely. This is a straightforward, reliable component that any nitro RC user—from complete beginner to experienced racer—will find dependable. If you're new to nitro and setting up your first nitro RC car, including this quality starter wheel in your setup from the beginning will help you avoid starting frustrations and build good habits for engine maintenance and operation.
• What makes a rubber starting wheel better than plastic or metal alternatives? — Rubber provides superior grip and friction against your engine's flywheel, preventing slipping and ensuring consistent torque transfer. Plastic wheels can become slippery over time and tend to slip under load, whilst rubber maintains grip even as it ages. This is why Fastrax has chosen rubber construction for the Tru-Start range, prioritising reliable starts over every other consideration.
