Factory Pro FP-O-XCP006 Xray T4-21 Reinforced Main Chassis with Dual Battery Mounts  [FP-O-XCP006]

Upgrade chassis rigidity for the Xray T4-21 with Factory Pro

The Factory Pro FP-O-XCP006 main chassis is engineered for the Xray T4-21 to provide a solid base for competitive racing. Included are two battery mount plates so your packs stay locked down, helping preserve balance and predictable handling through corners.

Benefits for racers

Made from resilient materials, this main chassis increases torsional stiffness and longevity under race conditions. The twin battery plates reduce power pack shift, which in turn keeps weight distribution consistent during aggressive driving.

Fitting and setup pointers

When fitting the Factory Pro chassis, tighten fasteners in a cross pattern to prevent warping. Position the battery plates to tune front-to-rear bias and fine tune corner entry and mid-corner traction.

Model fit and typical use

This component is built specifically for the Xray T4-21 and integrates with standard T4-series parts. It is a practical upgrade for drivers focused on stability and lap-time consistency.
