      Not sure exactly, but I figure much more than 70.

        Thats a nice boat & setup. I woulda took a little more of a chance with the power in the turns. It looked like it would have taken it.

          I have run 7XLs on 18 high-end cells in hydros - it is a very high-power setup, close to SAWs power. You can't find a prop small enough to keep the amp draw much below 100 IME. I used a Barracuda 125 and it worked fine. Don't run it for more than a minute without checking the heat.

          The Bandit has issues in turns with high power. It needs a turn fin to race competitively, but it is still cranky. With moderate power it isn't bad.
