      very cool!
      will that 24" do a full throttle turn?

        I was wondering that too? I have one on the way so I will run the heck out of it! This is going to be a great summer for sure.

          Like my gas KOS, it does not corner well and I think because it's so dang narrow?
          slow to mid speeds look good, but not full throttle

            All fast boats slide in a corner.with a cat turn right and the right side of the cat does the turning and the left side slides abit because the small over powered boats go so fast. the left side slides a bit so you need some angle to alow the water to pass under the left side. the MM has the right angle and width to make it one of the best turning cats to date. look at the back of a mm and look at the back of this cat. this cat has planing strakes on it and the ones on the out side will hook up in a turn and flip the boat. I would like one but I wold like the planing strakes taken off. this would make it turn much better. put some kind of removable filler in the planing strakes in the mold and make one with a bottom like a MM and it will turn better and then sell one like that to me.

            remember it's all about the laminar flow

              ok, way over my head...
              is there anything I could do to my Gas KOS to make it take the coners at full speed?

                  Brushless 55 e-mail me some pics of the bottom of your boat in side and out. The inside need to be close ups and of the out sides bottoms. The out sides I will need one from the back to. If the 92 is the same as the 24 It can be fixed.

                    The length to width also is a large contributor to the hull's running characteristics. For example, the mean machine may corner well, but I have not seen any break the 100mph mark. The hulls we build are scaled off the real thing and perform similarly.

                      Hi Justin,
                      I wanted to know what Kv the motors in that video were too? The motors I gave Rad to test for the current 24" cat are 4500Kv.

                        Those were 5100kv, but really junky. Rad is going to run yours and I am going to run a little better set of 4000kv. We should have videos next week some time.

                          A little "better" set than the 5100's Due to the load loss the 5100's had, our 4500's make more torque and will hold closer to their rated Kv

                              Can't wait to see more video's and the test results. Otherwise how is everything coming along Justin?

                                Good, so far, I am getting excited about performance. Seeing how well the boat ran with the cheapie motors the hull should literally fly with the current two setups we have. Should have more videos later in the week. We hope to get a radar gun on them too.
                                Other than that I am selling the pair of Neu's I traded you for. Obviously, I have many other projects that need the funds.
