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

Stainless steel reinforcement plate for 4C-120

This HA192 plate from Hatroi is an RC-scale stainless steel replacement designed specifically for use with the 4C-120 platform. At a nominal 49mm by 9mm footprint, the flat, low-profile plate serves as a local reinforcement or mounting surface where additional rigidity is required.

Intended compatibility is limited to 4C-120 as stated, so confirm hole pattern and clearances before fitting to other kits. The stainless steel construction resists corrosion and preserves a flat mating surface, making it suitable where a more rigid junction is preferred over stock material options.

Installation is straightforward: align the plate to the original mounting points, use the existing mounting hardware or equivalent fasteners that match the thread and length of the original screws, and tighten evenly to avoid distorting the plate or mating parts. Avoid overtightening and verify clearances for suspension and drivetrain components after fitment.

In tuning terms the plate is a simple hop-up to increase local stiffness, reduce flex at the attachment area, and provide a consistent reference surface for alignment during setup and testing. Test changes incrementally and record handling differences when fitting to a working chassis.
