    That is all we need. All three of us standing there, one covering his mouth, one covering his ears and the last one covering his eyes. LOL I will do some research on a ESC. Any suggestions? I will now have an extra ESC for the other boats. I have to say, for $48 it has done very well.

      For just to test now may be you can get the HV240a Damen has,
      Most people use that 200a esc you have for 4s setups,
      And 5s tops depending on the setups and boat.
      So you where using that esc in that boat before on 6s with the stock motor ?
      Or the stock 120a and than the 180a upgraded one ?
      ? ONLY IF THEY WORK

        After the original 120a popped, I replaced it with the 200a. The 120a popped on the second time out. The 200a has about two hours of run time on it, without a glitch with the 6s setup. From day one, I have been using a 6s setup. I was using the stock motor but did replace the prop to the next size up.

          They did not send you a upgraded 180a for the one 120a that popped under warranty ?

              Is the magic number 30,000 for this style boat? Speaking to someone and they are suggesting a 730kv with the 6s. I am thinking that would be to low in the RPM's. I calculated the numbers and 8s with a 1090kv came in just over 30,000.

                No 730kv on 6s would be a tug boat,
                Hears some numbers to look at.
                The stock motor was the V700 1100kv and on 6s*1100kv=27720.RPM

                6s*730kv=18396. 7s*730kv=21462. 8s*730kv=24528. 9s*730kv=27594. 10s*730kv=30660. 11s*730kv=33726.

                12s*730kv=36500.

                6s*1090kv=27468. 7s*1090kv=32046. 8s*1090kv=36624. 9s*1090kv=41202. 10s*1090KV=45780.


                Sorry I was tired last night and did not remember to add full voltages to the numbers,
                It is up to date now.

                  The stock motor was the V700 1100kv and on 6s*1100kv=24420.RPM

                  6s*730kv=16206. 7s*730kv=18907. 8s*730kv=21608. 9s*730kv=24309. 10s*730kv=27010. 11s*730kv=29711.

                  12s*730kv=32412.

                  6s*1090kv=24198. 7s*1090kv=28231. 8s*1090kv=32264. 9s*1090kv=36297. 10s*1090KV=41420.
                  The same numbers I have on the tool box. I think I am going to stay with the 8s - 1090kv. From the stock setup to this will be over 10,000 rpm's. That is a huge difference. Thank you for the numbers.
                  Did not know if there was a magic number with this size boat. I think I will be very happy. I just need to charge the new batteries and go. I installed the last piece yesterday which was the water line. I may balance it today at the 30% position and mark the inside where the batteries need to go. The way I did it for the first time when I bought the boat worked out very well, either I was lucky or it was right on the money.

                      Not only will I reply, I will have video. I use a GoPro strapped to my hat and there is usually someone that will use a video camera.
                      My thought on this is that it will either run like a raped ape or be a dud. LOL
                      As Lenny posted with the rpm of the combo, I think I will have white knuckles.

                                I have heard some negative stories about this motor. I thought about buying this motor until I started asking around on the message boards. The one thing everyone said was that it will not last long, the second thing was that it did not compare to an equivalent sized motor. I would do some research first. I spent a little extra and went with the Leopard. Not that I am trying to sell you anything, I do have a new Leopard 5692 - 730kv. I went with a 1090kv for my battery size.
                                Good Luck
