Xray T4-21 Scythe Type Option Upper Deck by Factory Pro O-XCP008  [FP-O-XCP008]

Option upper deck for T4-21

This Factory Pro O-XCP008 option upper deck is supplied as a Scythe Type option specifically for the Xray T4-21 chassis. It is intended as an RC-scale hop-up to alter the T4-21's upper chassis stiffness and balance without changing core drive components.

The part functions as an upper deck option that modifies the load path between shock towers and the central chassis, helping fine-tune flex characteristics for different track surfaces. Use it as part of a measured tuning process: compare lap times and handling response after each change rather than combining multiple untested modifications at once.

As an option part, this upper deck is for hobbyists who want to adjust chassis flex and balance on the Xray T4-21; verify fit and mounting hardware before track use.
