I have a 1989 DT55 which pulls hard to one side when using the T&T in the down position but improves slighty as it is lifted a little but far from perfect. It has stablizer fins on it which I'm not sure if that is the problem or not. There is a tab just above the propeller which has been moved both directions with no luck. I purchased this rig 1 year ago but because of this motor problem it hasn't been used much. Would there be somone who could please help me with this issue? It would be much appreciated. Thank-you
