- Enhanced Aerodynamic Stability — The wing profile is designed to generate additional downforce during acceleration and cornering, helping to keep your RC monster truck planted through aggressive manoeuvres and maintaining control on challenging terrain.
- Professional Black Finish — The durable black colour finish complements both the original XRT colour schemes and custom builds, whilst resisting UV fading and maintaining a sharp appearance even after extended use in UK weather conditions.

Technical Performance
The Traxxas Wing TRX7821 represents genuine engineering excellence in RC aerodynamic design. At 1/7 scale, this component is proportionally sized to deliver meaningful downforce contribution to the XRT's already impressive handling characteristics. The wing works in conjunction with the XRT's low centre of gravity, independent suspension geometry, and brushless powertrain to create an integrated performance platform that can handle aggressive driving styles. The precision manufacturing tolerances ensure that the wing mounting interfaces perfectly with XRT chassis variations, whether you're running an XRT VXL-8S with its 8S LiPo compatibility and VXL electronic speed control system, or the ultimate performance variant. The inclusion of four 4x12mm fasteners with the component package ensures you have everything needed for immediate installation. The black finish provides excellent durability for UK weather conditions, resisting the moisture and temperature fluctuations typical of British outdoor RC driving sessions. Build quality is exceptional throughout, with no flexing or movement once properly secured to the chassis.

Frequently Asked Questions
- Which Traxxas XRT models is this wing compatible with? — This wing is compatible with the complete XRT range, including the Traxxas XRT VXL-8S in blue (TRX78086-4-BLUE), orange (TRX78086-4-ORNG), green (TRX78086-4-GRN), and black (TRX78086-4-BLK) variants, as well as the Traxxas XRT Ultimate in blue (TRX78097-4-BLUEX) and green (TRX78097-4-GRNX) versions. The universal fitment across these models makes it an ideal replacement if your current wing has been damaged or you simply want a fresh look for your RC monster truck.
- What are the 4x12mm FCS screws used for? — FCS stands for Fast Clip System, and these four precision-engineered stainless steel screws provide a secure, vibration-free attachment point for the wing to your XRT chassis. The 4x12mm specification ensures proper depth and holding power without over-tightening, which could strip the composite mounting points on your vehicle's frame.
- Do I need any tools to install this wing? — You will require a small Phillips head screwdriver or hex key (depending on screw head type) to install the wing using the included fasteners. No specialist tools are necessary, making this a simple upgrade or replacement that can be completed in minutes as part of your regular RC maintenance routine.
- Will this improve my XRT's handling? — The aerodynamic wing generates additional downforce, particularly during acceleration and high-speed cornering, which helps keep the front end planted and improves overall stability. Combined with the XRT's advanced suspension geometry and brushless performance, this contributes to more predictable handling characteristics, especially valuable when you're pushing your RC vehicle to its limits on challenging UK driving courses.
- Is this a genuine Traxxas part? — Yes, absolutely. This TRX7821 wing is manufactured by Traxxas and sold through authorised retailers like RC Model Shop. Genuine Traxxas parts ensure perfect fitment, authentic engineering standards, and compatibility with your existing XRT platform. Choosing genuine components protects your investment and maintains the performance integrity your brushless RC vehicle deserves.
