The KO Propo RSx one10 Ver.D Aluminum Upper Case, model number 35042, swaps the standard plastic casing for a tougher aluminium cover. This upgrade helps maintain alignment under load for a more consistent control feel.
Constructed from durable aluminium, the upper case reduces unwanted flex and supports precise servo movement. That stability translates into cleaner steering response and steadier inputs on demanding courses.
Verify that your servo matches the KO Propo compatibility list before ordering. Fitting the aluminium upper case is normally a simple process that uses common hand tools to replace the original case.
