    The only difference is probably the custom options available but also when u handbuil you can bet that his specs are dead on. With the manufactured stuff its probably +/- 5 %. I run turnigy too love it but ist it better than a benz controller???180 amps is alot so to claim it u better be able to do it. But most manufactures rate thier stuff @ 90 percent of what it will do.For good reason ;we wanna take everything to its limits.One need to also consider this . If you wanna pull 60 amps continuous u better buy a 120 amp continuous esc over estimate always. In this hobby overkill is better.I tell you one thing Id buy turnigy before castle i bet you that cause those guys lied in my opinion on the screamer thread. Any esc maker in the world knows that firmware updates alone will not aways fix a problem .They knew that when they said it.

        This build or project is totally experimental. The goal is to make it as simple as possible. I have had great success steering large aeromarine avenger cats using such a dual motor set up but only at lower speeds. I want to try to eliminate the complexity of servos or ducted thrusters. I have tried these motors with large jacuzzi jet drives and they work great but the drive is 4 times the cost of the Leopard motor!

        One other factor is that the interior of the cat is most important for my specific application since it is loaded with electronic equipment including a small Pentium computer with solid state drive and three independent wireless video systems. Keeping the motor outside means only batteries and the ESC's inside whose location is very flexible.

        This a works in progress and it might be best after all to put the motors on the inside of the outer sponsons with a short, direct drive and again do steering by individual motor speed and direction. You certainly are right on the drag and I do not expect this to be any type of SAW record holder!

          Here is a Leopard 220O KV with water cooling in the motor mount only and fan cooling on the case. I run a complete Eagle Tree system on it with GPS. The boat is not tuned and in I run almost exclusively carbon props. However Josh gave be a three bladed polished prop and here is the Eagle Tree of the first run. 50 MPH is a non-set up condition is a good first start for this mono with my limited knowledge.

            I wonder if the OSE water jackets for the castle/Neu motors will fit. I'm guessing that they will.

              Otherwise, it may have the same can O.D. as a Neu 1515.

                  I'm really interested in the 36-74 1290kv or 1790kv. http://www.leopardhobby.com/product/...ionID=01020211

                  Just can't find a anywhere to place an order for these motors.

                    Almost....The China factory I deal with makes the Pursuit and Genesis. However the specific ones they sell to Hobby King are different. They actually have 3 or 4 slightly different models on each of the boats. The boat in the picture is one I bought in China in person and hand carried back as a bare hull with drive hardware only.

                      I gave one of these 2200KV Leopard motors to MarkF for testing on the new Insane Hydro. We ran it with NO type of cooling at all, but only for short, fast runs. MarkF said he had a water jacket for it so hopefully he will read this and add his comment as to the specific type of water jacket he was thinking of putting on it. I think he said he got the jacket from OSE.

                        are those equal to a 1515 in their size?
                        I'm getting really jazed by the possibilities of these motors

                                I have a little of every thing and a made in the USA 240 that is smoked after 3 passes and only got to 90 in temp we will see if they will warranty it lol. I would just like to say this if it was not for or knockoffs a lot of poeple would not be able to do FE becouse of the price of the parts just my 2 cents. and I hope they will give me a new 240 ESC or next time I will buy chines.
