XRAY 373515-K X1 Composite Rear Wing (High-Downforce)  [XR-373515-K]

High-downforce rear wing for 1/10 formula RC

The XRAY 373515-K X1 composite rear wing is an RC-scale accessory engineered to raise rear-end downforce for 1/10 formula racing platforms. The wing's profile concentrates load at the rear axle to increase traction and directional stability on high-speed straights and during corner exit, without implying any real-vehicle application.

Approved for ETS competition use, this wing is intended for model-level tuning where aerodynamic balance is critical. In practice the component serves as a predictable aerodynamic lever: increasing wing angle raises rear grip with a corresponding increase in drag, while reducing angle lowers drag and rear grip. Use this behavior to tune understeer and oversteer tendencies on compatible X1 chassis.

Installation and tuning notes are intentionally general to avoid adding hardware specifics. Fit the wing to the X1 series wing mount points and verify trim and symmetry before track sessions. Small incremental angle changes are recommended when testing setups to isolate aerodynamic effects from suspension and tire variables.

For model racers seeking a straightforward aerodynamic upgrade, this composite rear wing provides a stable baseline for downforce-focused setup work while remaining compliant with ETS event approval.
