Ive been looking about for an alternative to hydraulics for my Bruder excavator conversion and came across these:
http://www.active-robots.com/product...6-R-3541.shtml
Does anyone know anything about these or used them before?
It mentions in the discription "Direct replacment for a regular RC hobby servo" so does this mean it can just plug directly into a standard RC receiver like a servo?
Thanks
Paul
