    Well I made it out again and ran the 2114 ABC’s and got a couple good passes. Then I switched to 1916 ABC’s and got a few more. Both sets of props are cut down to 47mm. My high speed was 77mph and was from the 1916’s. Pulled 220amps for 2/10ths of a second then ramped down quickly.
    Wasn’t a pretty day out there and I shook a bearing loose from the stinger again(same side), and still a pita to get on plane. Tried a tad less negative on the stingers AND some weight in the tail to get CG to 30% after these runs to no avail.

      Here is the first running the three blades: https://youtu.be/bMG3I7RMXcc



      And here is the 1916’s: https://youtu.be/Z6CCNMcoyQs

        It's tough to see how the boat is actually running at that distance, at least with my tired eyes, but the 1916's certainly sounded like you were able to stay in it longer, and resulted in longer, smoother sounding passes. I'd stick with those for now so you can at least take one variable out of the equation and focus on COG and trim moving forwards.

          Agreed, next here is running outwardly spinning props. This will switch the shafts around so I can see why that one bearing keeps shaking loose. A fine vibration but driveline alignment or the shaft itself? I don’t really want to up the voltage till that is remedied.
          Should get it out tomorrow.

            If you run the props outwards, should use megative drive angle and is more fun at corners..But no for high speeds..
            If you run props inwards,Should use positive drive angle and is F....k difficult to drive at slow speeds..BUT perfect for high Speeds!!
            Well I will put credit where it’s due. Tried outward and takes off beautiful but.... now it has that old Geico bounce at speed. Guess I have to decide whether I am to run this one or SAW It! I can tune the bounce out I’m sure. And if SAW then I’m just glad I’ll never be running the lights and squaring up for a run.
            Oh and the other bearing broke loose so I guess that one cable needs a going over. Perhaps the stub is tweaked.

              Hi...
              This lake is small and you can't see what really wants the boat or you...!!
              With outwards props i would made long straights and big turns.....

                Agreed Nikolas, but this lake is close to me and I did discover the bad propeller shaft. Now I fix and go to the bigger lake. Thank you again for your words.

                  Especially cats, cause of the tunnel aerodynamics needs to adjust for high speeds..
                  example....you may setup your boat lets say for 6S with 1715 and max 70mph at a small lake...Then you go to bigger lake and you prop up or voltage up....And here comes the lift off..!!!!!!!!!

                    Yes yes. I agree.

                      Ok, upon the advice of Mr Manuel Wenny I switched the start power on the ESC’s from ‘standard’ to ‘fast’. I also switched cell detect to ‘auto’ so I can freely change cell counts.

                        What change did you feel while driving after adjusting the ESC setting?

                          Ryan, it was like night and day with the control on the throttle. I don’t really get it but it must be just another glitch with SW ESC’s. I know that Travis found timing and cell count set to ‘auto’ was best. Just gotta be a sync thing.

                            Wow your still out there! I would think the lakes would be starting to make ice up by you . we are suppose to get snow down here tonight. Looking good!

                              Well outside of the last two years it usually barely freezes in Vancouver. It is likely tho, the only place in Canada

                                I never did like the setup on the swordfish ESC's myself. The weirdest one was having to do a throttle calibration then set throttle range on the transmitter to 115% in order to achieve full throttle on the ESC.
