HB TCXX Upper Deck 2.5mm - Arrowmax AM-TCXX-68761 Tuning Component  [AM-TCXX-68761]

Replacement upper deck for HB TCXX

The Arrowmax AM-TCXX-68761 2.5mm upper deck is an aftermarket top-plate compatible with HB TCXX chassis. It functions as a chassis tuning item to alter top-plate stiffness and support the vehicle's layout, rather than being part of the electronics or driveline.

Fit this deck when experimenting with different top-plate stiffness on Hot Bodies TCXX cars. When installing, check clearance for the servo, route ESC leads carefully, and ensure shock towers are unobstructed; re-torque mounting bolts after the initial run. Moving to a 2.5mm plate will alter the chassis flex compared with thinner originals, producing tangible changes in handling and weight transfer under acceleration and cornering.

A dedicated tuning part for HB TCXX users focused on setup refinement and chassis stiffness testing.
