Guys I have the fuel problem solved with a new tank and it is a not as tall as the flex tank i removed so it fits nicely.It runs well now and can find the needle much better and looks promissing.
Now i have some handling questions.Whwn the boat is running on the staights it is fine and tracks well and very little pull left or right however I am in a small pond for now and when you come around and get in your own wake or waves the boat seems to want to hop sideways for lack of a better term ...it looks as though it breaks loose from the water momentarily and then sets back down or in some cases it will rock left to right on the sponsons and blow off all together.
I am using the sipkits rudder that i thinned substantially and i am using the zipkit Turn fin and hane tried it in the middle, rear and was about to try it in the forward holes but ran out of daylight.
could someone help me with setup info i would like to get the 12 raceable before i start on the 21 .
