There should be a centerblock valve in the kit. The ones they got in there now, the spool stays where it is and keeps the actuator closing or opening even after the button is released. A center block valve returns the spool after the button is released. This way the actuator can be stopped at any point, not just 100% out or 100% in. THis part should be included in next year's kit.
