I thought it would be a good idea to redo this and make it sticky so I can find it easier. It’s relatively easy to use the HSR-5980 and HSR-5990 servos with their built in pivot point. You must enlarge the hole across from the servo output shaft to accept the plastic bottom of the servo. This makes for a very strong joint.
It does not matter if the flange on the bearing is on the inside or the outside of the “C” bracket. Just use the method that fits the best.
