If you run hard lines or rough surfaces, the KO Propo 35034 - RSx3 Aluminum Upper Case gives the RSx3 servo a tougher outer shell with improved thermal behaviour. The machined aluminium construction enhances longevity without compromising fit.
Aluminium is valued for being strong yet light, offering protection for internal gears while aiding heat transfer. Fitting this upper case helps the RSx3 stay cooler during extended sessions and heavy duty use.
From practice sessions to race day, this upper case keeps the servo performing steadily under repeated stress. Better heat dispersion lowers the chance of thermal-related performance drops when you push the servo hard.
