This aluminium uppercase is aimed at hobbyists who need a tougher housing for the KO Propo 35051 RSx4S servo. Built to resist daily wear, the metal shell also helps spread heat away from the servo casing under load.
Aluminium brings durability with little penalty in weight, making this uppercase a solid choice for competitive drivers and club racers who want consistent servo behaviour without excessive mass.
Mount the uppercase with care and check that screw threads are clean before tightening. Regular post-run checks will ensure screws stay secure after hard impacts or long sessions.
