    i'm gonna try that.....raising the strut....

        I saw something about flat bottom struts.... Maybe you could modify your strut if you can't get it to ride by lifting the prop.

          I'd try a bit of positive on the strut.................

            OK now you guys are stretching I think the setup he has now is pretty close if he has full throttle. Travis just try it now with the ESC calibrated correctly and see what happens.

              Not stretching if his throttle was set right.......????...........we are all thinking its the setup not the darn throttle................That would be the first thing that should have been checked...........

                I think the suggestions of calibrate the throttle and run it first, without any setup changes were based on this comment. I would think that judging the rpm on the bench would prove a bit challenging if it is your first time spooling up a 2pole, compared to multiple times with 4pole motors.

                Have a feeling that he will have some great news on accomplishments with the new hull after his outing, this evening.

                  I'm certainly pulling for him

                    Just ran it. It's much faster. On 6s it's faster than it was on 7s before. Went 69.1mph on 6s (went 61.7 on 7s before throttle recalibrate). Went 75.4mph on 7s. I made NO changes other than recalibrate throttle. I think the prop is still too deep. It did air out more but I've got some tuning to do. It'll be in the 80's this weekend if I can get to the lake. Stay tuned for videos. You guys are gonna enjoy the 6s one...

                      How about that, 100% throttle makes a big difference I'm glad that did it, now you can really tune on it! I'm sure you'll have it running in the 80s this weekend, probably 90s if you put it on 8s.... Also if everything is still running cool then put more prop on it!!

                        Sounds like you had a good outing. Anyone want to take bets that he will get this to? 87mph?
                        I am sitting on your YouTube page clicking refresh..... lol

                          The MGM ESC calibrates different, you not only have to calibrate your TX you also have to calibrate the ESC for full throttle.

                            So if you want to cruise at 35mph just change your throttle setting to 50%!!!!

                            JK...............good job

                                Thanks fellas. My actual goal with this was 80mph. I didn't want to say that because I don't like to count my chickens before they hatch....but I've had 75.4 of them hatch so far so I can say I'm pretty close. And this is only the second run. I'm going to be fighting some chime walk now so that's going to be a new learning curve on how to cut it down some. The water wasn't exactly smooth which is kind of needed for these speeds with this small of a hull. At least that's what I think anyway. I'm hoping that raising the strut will help some now. I'm uploading my data log at the moment so I'll check my amps again when that's done.


                                Looks like it's mid 200's with a peak of 399.
