Premium servo extension leads are manufactured using the renowned PowerBox Premium cable. The cable is extremely flexible, and is made up using very thin individual strands in order to pass the maximum current through the given cross-sectional area of 0.35mm². The insulation is made of a special material which is also employed in full-size aviation. It is virtually indestructible, and offers excellent protection even when reduced to just a thin film around the copper conductor.
This insulation produces a weight reduction of about 30% compared with the conventional PVC. The cable ends are enclosed in heat-sink sleeves and are fitted with high-quality transparent UNI plugs and sockets to ensure that the servo extension leads are perfect.
