    I have three or four of those motors. I use a cut-down X427 with them on the 15" H&M shovelnose hydros to keep temperatures within limits.

          I don't know if you guys remember Radek, but he built a small cat like this maybe 7 or 8 years ago. We started off with in runners in the 3000 range and used 2 and 3s lipos. Then some started using out runners and this became popular because it could spin a bigger prop. Then the problems of torque roll started happening. We found with a narrow cat it would roll on it's side if you went to like a 632 or 435 prop. I don't remember what kv was being used so that's why I asked what was going on now. I will see how my set up runs with a 427 prop and if it looks like it can take more, I will get the bigger motor. I got the boat for free so don't mind messing with some different set ups. Curious what speeds some of you are getting with this hull. I know we had a hell of a time trying to get one on radar. Are there some small gps units that will fit this size boat?

            You could always build one of these as a twin.....

              The best choice you can do :




              The cheap green motor is very small IMHO, look at GARTT : https://www.ebay.com/itm/GARTT-3700K...UAAOSw~PJbcq9u

                    I can make a motor mount but it wont have water cooling. Should I get one that does or am I going to be alright with 4 or 5 minutes of run time without one. I have an 82g outrunner, the size you guy's recommended.

                      I finished converting mine over to brushless. Here is a couple of pics of the finished boat. Nothing to crazy and I wanted to thank those that helped with my questions. I haven't run it yet but hope to in the next week or so.

                        Great job Mark! Need to get back to mine. Let us know how she runs!

                          Looks great man! Love the minis, I'm addicted to running tight ovals with my mini rigger. Let us know how the Geico runs.

                            I got it running and it runs decent. Finding the right prop is what I need now. It's fast with a 632 but torques the boat a little more than I like. My 427 cavitates to much so I will try some bending on the prop to get it to bite. The 4400 kv motor I'm using is probable better suited to a rigger so I may switch to a 3000 to 3500 kv motor.
