After getting my 250se i went to take the rotor head appart to clean and grease it,and found that the flybar holder is using brass bushings where it attaches to the center hub.So i looked in the trex 250 manual and found that it uses bearings there,and they are the same ones used where the flybar sticks into on the flybar holder.So i orderd a set of these bearings to upgrade the brass bushings on the mounting point of the flybar holder.Will these work or can i do this
