4C-120 Low-Profile Stiffener Plate HA192 49mm x 9mm Hatroi  [HA192]

Low-profile stainless chassis plate for 4C-120

The HA192 from Hatroi is an RC-scale stainless replacement plate designed for the 4C-120. At approximately 49mm by 9mm, the slim, flat plate acts as a local stiffener or solid mounting surface where stock parts may lack rigidity.

Note the specified compatibility with 4C-120; verify hole alignment and clearance before fitting to other models. The stainless finish helps prevent corrosion and preserves a true contact surface for stable assembly.

To fit, align the plate to the original mounting points and fasten using the existing screws or suitable replacements that match thread and length. Tighten progressively and avoid over-torquing which can bend the plate or stress mating parts. Recheck suspension and drivetrain movement after installation.

As a tuning part, this plate provides a straightforward way to stiffen the attachment area, reduce unwanted flex, and maintain consistent alignment during setup. Make changes gradually and test to note handling differences.
