KO Propo 35040 - RSx3 12 Aluminum Upper Case Reinforced Cover  [KO-35040]

Machined Aluminium Upper Case for RSx3 Servos

The KO Propo 35040 - RSx3 12 Aluminum Upper Case replaces the stock top with a machined aluminium shell that improves durability and thermal behaviour. It is targeted at modelers who expect consistent steering under demanding conditions.

Durable Alloy Housing

The aluminium body resists wear and impact better than standard plastic tops, offering a firm housing that keeps internal components aligned. The precision fit helps avoid slop in the servo mechanism.

Maintains Control in Hard Use

When subjected to high torque and quick direction changes, the KO Propo 35040 helps the servo keep accurate positions, which is key for tight cornering and predictable handling.

Compatible with RSx3 Line

Specifically made for KO Propo RSx3 servos, this upper case allows a direct exchange with the original cover. Installation is straightforward, but always verify travel and horn clearance after fitting.
