XRAY T4-21 Main Chassis with Battery Mount Plate 2pcs by Factory Pro O-XCP006  [FP-O-XCP006]

Chassis overview and tuning role

This Factory Pro FP-O-XCP006 replacement is an RC-scale main chassis designed for direct use with XRAY T4-21 models, supplied with two battery mount plates (2pcs) to offer alternate battery layout options. The component is intended as a direct spare or upgrade to change battery position and influence weight distribution and handling during setup and tuning.

The part is supplied as a single main chassis assembly package that replaces the original chassis plate. When fitting, check mating points for servo, ESC, and motor mounts, and confirm alignment of drive shafts and suspension pickup points before final tightening. Minor trimming of factory foam or brackets on the car may be required to clear the plates depending on the chosen battery layout.

Use this chassis as a tuning lever: moving the battery forward or rearward with the included plates helps adjust front/rear balance and transient response without changing suspension geometry. Verify compatibility visually and with trial assembly before running the car on-track.

For racers and hobbyists swapping chassis plates or experimenting with battery placement on an XRAY T4-21, this Factory Pro unit provides a direct replacement path and straightforward tuning options; always verify fit before finishing assembly.
