Further down, from pos.one to two, the sound was gone. Did anyone of you experience this problem? Could it possibly be solved by oiling the control rod tubular bearings? If so, what type of oil is to be used?

It's for an Allegro 2000. Any suggestion how/where to find such a part might get him flying again! Thank you for your concern to help him out.

See attached photo. They are located close togather in the area just behind the bulkhead rib that the the pilot seat belts are bolted to. These could be drying out for some reason. I would not use oil on them. Instead I would try a silicone lubricate on them. You should be able to find this in an aerosol spray can. If this does not solve the problem, check the two corrugated rubber sleeves at the ends of the flap tube where it penetrates the fuselage. Spray the rubber sleeve/fuselage contact surface with some silicone spray as well. While you are doing all of this check the flap servo motor screw. Make sure it is well lubricated and not binding because it screws into a plastic housing that has (neoprene??) threads. I use white lithium grease on the screw itself. Let us know if this works.
