The upper shaft(where the remote mounting clip is attached) on my ORX is really difficult to slide in and out. The paint has been worn off on the side where it is making contact with something inside the tube. I took the mounting clip off and removed the shaft so that I could clean the inside of the tube. It did help a bit, but it still doesn't really slide as freely as it should. Are any of you having the same issue and if so, have you found a solution? Thanks
