We found that tightening the steering cables rectified bad shimmy on the straight shaft tail wheel.Although the suspension tailwheel with the rubber blocks still shimmied badly after that I suspect it might be related to softening (or hardening?) of the blocks over time that may be involved.With the super Cub we found keeping it highly inflated helped a lot on sealed surfaces which would have been due to less tread surface making contact with the bitumen I think.The other possibility is a slightly bent vertical shaft due heavy landings and thus throwing the geo.etry out. There is a hell of a lot of load on the tailwheel on landing particularly on rough ground.Laurie

The belly is full with brake fluid, however the brake still works well. Do you have experience with it? Is it a Cessna cylinder? What kind of parts should be ordered for repair and do you know the specifications and source? With many thanks and best regards Gyozo --------------------------------------------------------------------- You are subscribed to the Dimona Owners Group mailing list.
