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 control surface 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.

Note these are not intended for DLG use, as the torque springs used on discus launched gliders are not strong enough to cause the KST X08 any difficulties. These are intended for larger models/control surfaces that require stronger springs.

 Review by:

I have been waiting on this spring loaded servo helper since I saw it described on Vladimirs website. I used them in my twin boom Plus model, and they have enabled me to add extra torsion return springs to the elevater/rudder which results in a more positive/accurate control surface movement. Very easy to fit, but one pulley needed its outside dia. to be reduced slightly to stop it fouling the inside tail boom which forms the servo mount position.
