Hatroi HA192 49mm x 9mm Stainless Reinforcement Plate for 4C-120  [HA192]

Stainless stiffening plate tailored to 4C-120

This Hatroi HA192 plate is an RC-scale stainless steel replacement intended for use with the 4C-120 platform. With a nominal footprint of 49mm by 9mm, the thin flat plate provides a local stiffening point or a firm mounting pad where stock material may flex.

Intended compatibility is the 4C-120; always check the plate's footprint and hole pattern against your chassis before attempting a fit on other kits. Stainless construction resists corrosion and maintains a true mating surface for reliable assembly.

Installation is straightforward: position the plate over the original mounting points and secure it using the original screws or matching fasteners. Tighten in stages to keep the plate flat and avoid distorting nearby components. Confirm suspension and drivetrain clearances after installation.

From a tuning perspective, the plate is a simple upgrade that increases local rigidity, helps reduce attachment-area flex, and gives a repeatable reference surface for setup checks. Introduce changes stepwise and record handling effects.
