The KO Propo 35048 aluminium upper case is produced to match the BSx4S-one10 Grasper2 servo. The metal top adds rigidity and protects critical internal parts while keeping weight compact to preserve handling characteristics.
Installing the aluminium upper case improves heat spread from the servo body and strengthens the casing against impacts and torque loads. This is especially useful for extended runs where heat build-up or strain can affect performance.
The part replaces the stock upper case using the servo's original fixing points, meaning installation is straightforward with common tools. It offers a quick way to upgrade durability without complex modification.
