Hi John, Thank you for your answer, I will remove the vertical spindle for revision. Now i'm thinking to change the antique tailwheel for sprung tailwheel, maybe the vibrations disappear. Certanly landing on the grass, recuce vibrations. Regards, Angel P.S. Another question, I have to change the fuel filter but I noticed that it's neccesary to remove the fuel tank!!, and it is necesary to change every 50 hours. I think the problem end making a search below the fuselage skin but reinforce the zone . Do you now if somebody made this search? I apologize for so many questions, I adquired reciently the plane and sometime I was a little lost, also for the language because I do not speak English, only Spanish.

The bend can be barely visable but measureable when removed. Castering wheels must have a verticle spindle. Rarely caused by the wheel itself. Landing on grass eases the problem a bit.

The plane only has less than 100 flight hours but has been 15 years standing in a hangar without flying. In the last flights, the plane upon landing has large vibrations in the Ruder. Anyone know what may be the cause? the plane has the old tailweel, can this be the reason? Regards, Angel
