The KO Propo 35033 aluminium upper case is crafted for BSx2/3 servos to give a stronger external shell. Constructed from durable aluminium, the part shields internal components from impacts and supports consistent servo behaviour during high load use.
Aluminium is prized for a good strength to weight ratio, giving robust protection while avoiding excessive bulk. Swapping in the aluminium case boosts impact resistance and helps move heat away from the servo, which is useful for extended runs or heavy duty tasks.
This top is engineered to match KO Propo BSx2/3 mounting points and clearances, so alignment and function remain intact. It is a straightforward replacement for worn tops or an upgrade when you need added toughness.
