Ron and Randy, i think your right about fishtailing in low wingers,i fly a gangster 52 which as had nearly 500 flights, and every flight the tail wobbles, i thought it may have been a mistake in my building,but obviously not. Im going to go with the manual on the tail wheel and see how she behaves, i may well change it later.What does yours weight in at Randy? Im expecting between 13 and 14 pounds. Thanks, Frank
