RE: new boat, same problem
Crispyspa,
Good luck on tweaking your boat. Stay at it, don't give up. That is another "Fun" phase of rc airboats....getting the engineering right to get the boat to run like you want it to.
My latest step hull went through several trials before I got the step right....almost threw it in the garbage at one point. It pays to experiment.
Let us know how your progress goes.
