The KO Propo 35051 RSx4S aluminium uppercase is designed for modelers who want a more durable housing for their servo. The alloy construction increases resistance to knocks and helps move heat away from the core components during continuous operation.
Aluminium combines stiffness with modest weight, making it a preferred material for upgrades where protection and thermal behaviour matter. This uppercase preserves servo functionality while reinforcing the outer shell.
When fitting, use the correct screw sizes and tighten progressively to avoid distortion. Inspect fixings after rough runs to ensure alignment and maintain precise control response.
