    Oh Boy Jim, PLC is gong to be fun now !!!

    I like to run the strut up high to keep the motor a tad unloaded & up a bit to get the front of the sponsons out of the water under wot.

        +1 on what Propperchopper said. Also, if you blueprint you can run the strut angle flat. See my note above for a how-to on blueprinting.

          Thanks to the info. I watched your tutorial and blueprinted the bottom the way you suggested. It came out very nice. Flat & sharp edges.

            I just received my Lucas boat yesterday and was wondering about strut height. The Lucas hull has stepped sponsons, and when set on a flat surface the back of boat is up off of surface due to the stepping. Should I set as boat sits? Or do I hold back of hull down on surface and then set height?

                I don't have back-to-back GPS data for a before/after comparison yet but I can verify that the boat needs much less positive angle on the strut to carry the bow, which should equate to higher speed. After blueprinting, I ran the boat with the same strut angle as before, and the boat porpoused because it no longer needed that much positive angle. The boat handles better and certainly appears faster.
