    Check your trim tab, either one of it were out of angle.

    sounds like your trim tabs arent set right and boat is off balance. take inner trim tabs off and shift battery weight around make sure your strut is at 0 degrees. what is your whole setup and lipos?

    Servo is fine you can get boat straight when using steering but at high speed its hard enough to keep boat in the water and jim82 it's fine on 4s but I'm on 6s 3x3s . . . esc and everything else stock apart from trim tabs I'm going to keep trying different things can only think its trim tab because it was fine before another go Sunday rain or snow for uk tomorrow

    You should also have the item # 5731 for a well tuned adjustment of your trim tabs like what I have on those images.
