If you use the rubber gromets, and brass inserts in the Futaba servos, they should then sit flush on the servo rails, as well as be isolated from some of the vibrations.
paul, good point. I think 90% of the guys I've seen do this wrong. They put the brass haed against the screw head, negating the isolation value of the rubber mount. That aolone would make a good tip.PaulSwany said:However, if you put the "head" side of the brass bushing against the rail, it should sit flush without the notch.
