    The cooling jacket arrived today, Dave did a great job on it. I mounted it on the motor and pressure tested it, the fit is perfect and no leaks.

        I have a bit of concern for the high position of the motor in relation to the cg of this boat. I can see the possibility of the higher cg being an issue at the speed this boat should go. My experience in gas boats tells me to get everything as close to the bottom of the boat as possible. Higher weights will make it difficult to handle well. Good luck and we shall see.

          It may not look like it in the pictures, but the motor is about as low as it can be while still keeping the stuffing tube with a single bend. There is only 1/16'' between the bottom of the cooling jacket and the hull. The motor is set at an 18 deg angle, I've set up a few hulls with that motor angle and it works well for me. The only way to get the motor lower would be to lay it flat and have an s-bend stuffing tube, I prefer a single bend.

          With this boat coming in around 20lbs, of which there is 7lbs worth of packs in the sponsons, it should stay planted to the water. Also the boat really isn't going to be all that fast for it's size, I'm expecting aroound 65-70mph. Thanks for the input. Hopefully the way I layed it out makes for a good running boat, I guess the maiden voyage in a couple weeks will answer that

            This boat has a lower vertical CG than a gasser could EVER have. Look at all the lipos in the sponsons! Let her rip!!!!!!!

              Dozens of racing FE Conquests/Avangers have shown that the CG is just fine for performance racing. Moving the motor up or down an inch has little effect. Rummy has it nailed, with the packs low in the sponsons the CG is lower than in similar gas boats. The photo angles are a bit deceiving.

              Here are a couple more examples of awesome handling FE Conquests. BTW there is nothing wrong with an "S" bend, it can actually reduce cable drag in many cases.

                    Well She is just about ready for the pond. The new(longer) connecting rods for the motor mount arrived and are installed. All the plumbing is done and tested. All thats left at this point is to bench test everything, as long as that goes well the first run should be next weekend.

                    As far as the initial setup, for those of you with a similar cat, where should I have the strut hieght/angle and cog? Right now I have the bottom of the strut 5/16'' above the bottom of the sponsons and at zero deg. My cog is set at 32%, but has alot of room for adjustment. I'm planning on starting with an x460 or x462, I also have an x465 and x467 to try if all goes well.

                    Here are a few pics of the finished product

                          Thanks Rum and Peter, it was a longer build than I had anticipated but worth it. Hopefully the payoff will come when this 2230 roars across the lake.
