Frequently Asked Questions

• Will this wing and wing retainer fit my Traxxas RC car? — This assembly is engineered specifically to fit the Traxxas #9421 body shell. If your vehicle uses the #9421 body, this wing will fit perfectly. If you're unsure which body your car uses, check your vehicle's documentation or contact our team at RC Model Shop—we're happy to confirm compatibility before you purchase.
• What are the 2.6x12mm Button Cap Screws (BCS)? — These precision fasteners are the standard hardware Traxxas specifies for wing mounting on this platform. The 2.6mm diameter and 12mm length provide secure clamping without over-torquing, which could damage the plastic body. These screws are engineered to stay tight during driving and are easy to remove if you need to adjust or replace the wing.
• Is this suitable for beginners? — Absolutely. Installing this wing and wing retainer is straightforward and requires only basic mechanical knowledge. If you've assembled any RC car or performed basic maintenance, you'll find this installation simple. The included screws mount the wing securely with just a few turns, and the clear design means there's no confusion about correct orientation or fitment.
• Can I use this wing on other Traxxas bodies? — This wing and wing retainer is specifically engineered for the #9421 body shell. Whilst some Traxxas bodies may have similar mounting points, using this component on a different body could result in poor fitment, misalignment, or damage. Always verify your body number before purchasing replacement components.
• How durable is this wing assembly? — Traxxas wings are engineered from durable plastic materials designed to withstand impacts and environmental conditions. The wing can sustain normal driving stresses, though accidents at high speed or heavy impacts may cause damage. This is why replacement wings are available—they're engineered to be replaceable, allowing you to maintain your vehicle after damage occurs.
• Do I need any tools to install this? — You'll need a small Phillips head screwdriver or hex driver compatible with the 2.6x12mm button cap screws. Most RC enthusiasts have these tools already. The installation is simple enough that experienced modellers can often install wings without tools if the screws turn freely by hand—though using proper tools is always recommended for secure fitment.
• What if my wing is damaged—can I buy just the wing? — This product includes both the wing and the wing retainer bracket together. If only your wing is damaged, you may be able to source replacement wings separately, though the complete assembly offered here ensures you have all necessary components for a proper repair. Contact RC Model Shop if you need guidance on sourcing individual components.
