I still have not corrected it, but I have ground the rudder quite a bit with an angle grinder, and it has done nothing for me, seems as if I can't even feel the tension due to the grind, maybe its a little firmer... I actually did check it with someone turning the wheel, and the rudder does turn with any movement of the wheel, and is very sensitive. make a small turn on the wheel, and the rudder does move. Im still not satisfied with the handling of this boat compared to others, hard to keep straight down the slalom course.
