The VM Spring Loaded Pulley Set for X08 Servos is an aluminium pulley with splines to fit all X08 servos, for use in pull-spring control surface actuation. What makes this very special is that a coil spring is included to offset the pull of the spring, so the servo is not under strain all the time. This increases servo longevity, servo performance and reduces current draw, increasing battery life too.
A very clever solution to a difficult problem, showing what a great engineer Vladimir is.
Two pulleys and coil springs are included.
