    Ran this thing today. Definitely takes some getting used to especially since I decided to go 4S but what a blast. Heck, I think this thing does better donuts than both of my air boats.

    With that being said, I was experiencing quite a bit of porpoising especially as I got near full throttle. My pond water is always a bit on the choppy side due to the pond fountain in it that runs all day.

    To stop porpoising, is it best to adjust the nozzle up or down???

We do all our testing with the batteries we recommend and we only experienced what you are describing with weak packs that fell off voltage under load.

      Like I mentioned above, try and not power off the boat and get each cell's voltage. This will get me a better idea for what is happening with your ESC and your packs.
      Ok I believe I found the problem. The motor had some resistance when trying to turn it by hand and it had a clinging sound as it spun around. I noticed what appeared to be small square magnets right beside the Dynamite sticker of the motor hanging out past the gap where they shouldn't be and I touched it with my fingernail and it seemed to go back into place. Now no more clinging and ran smooth, so I went and tested it and it ran fine 31mph(WOW!!!) on 3s 3800mah for almost 8 minutes and then I bring it back in take the cover off and put in a 4s battery to try that and the I noticed the resistance was back in the motor so I noticed the square magnets or whatever they are had shifted again so I pop them back with my fingernail and try it again for a real speed run, LOL....but the boat would only go about 10mph from the start, so I bring it back in and motor spins free change to another battery and same thing 10mph so I believe I have a motor issue and not a ESC issue. I think the extra resistance from the motor yesterday was causing the ESC to go into overload protection and not LVC like I initially thought, so now I have a motor on the way from Horizon. Does anyone think my theory is right? I don't know a whole lot about brushless internals. I would bet anything this Boat will do 35 mph on glass water running 4s 40-50c batteries. I will find this out if I can ever get it to act right again. LOL

        They chose it on their own, I had no idea. It was a humbling surprise.

          LMAO on the donuts....I feel your pain....You can only go up on the jet discharge tube because it s all the way down from the factory. Raise it up and you will really spin out on high speed turns unless you are in high and heavy rapids ..Ask me how I know Lol...

            The donuts were a blast due to the shear volume of water that was getting kicked up and it was about 1/4 to 1/2 throttle. I'll get video the next time I do it.

            I noticed the nozzle was tilted all the way down. I ran it in the stock position this morning, raised it a tad and tried that this evening. Maybe this is just the nature of jet boats at high speed.

              The nozzle is pointed all the way down to allow the boat to run as smooth as possible on open water, which is where I assumed most people would run. If running in a rough stream where you need to keep the bow out of the rapids and I'd advise adding some positive trim.

                Sounds good. I'll give it a try.

                This is definitely a new experience for me. I'm normally used to air boats and standard prop boats but I love this.

                  The magnets did come unglued in the bell of the motor if anyone is still in suspense on my issues. I glued them back in place but it looks like my coils suffered some slight damage as well. I did run two more packs through it after I re-glued them in with Baking soda and CA glue and it ran fine. The motor isn't perfect but I did eliminate the ESC being the issue with the (LVC). Hopefully this isn't going to be a wide spread issue. Anyways, I hope I helped someone if they have similar issues.

                    I found that I had 2 magnets loose in my motor as well. I took the motor apart and glued the magnets back in place with CA. I'm just wondering if I should trust this motor or try to request a new one from Horizon.

                      I told Horizon what my problem was and they are sending me a replacement. This is a lot of money for a boat of this size and if I were you I would request a replacement as well. I don't know if this motor is trustworthy or not. It looks like it was developed just for this boat a few weeks ago. This really concerns me...I was hoping it was just a fluke with mine. I question if this motor is capable of being revved out of water and causing it to potentially sling magnets. We have no choice to rev it and almost abuse it (so to speak) using the self righting technique.. Or maybe the motor is heating up to much and causing the CA to start to melt then causing this problem. Mine only felt warm every run. Let's see if Rafael has heard anything else about this.

                        I think that's what I'll do. If this motor decides to fling a magnet or two at 30,000+ RPM, that will be downright ugly. Not to mention I disassembled my pump assembly earlier to grease it and found signs of minor scratching on the inside of the pump housing. It appears the impeller was slightly rubbing on the pump housing. Thankfully I was able to clean up the edges of the impeller blades with my fingernail.

                          Did you experience power issues and then check the magnets or just notice them loose?

                            I just noticed they were loose. I then remembered your posts about your motor issues.

                            Heck I'm glad though. I really wanted to run the crap out of this thing this weekend but I might have just avoided a potential catastrophe. I'm not sure if you know this but the fact is that if a brushless motor blows up, it can and may very well take out the ESC with it.

                              Thanks for bringing up the issues with the motors. I'll discuss this with my team since we didn't see any like this during development.

                              Please don't risk glueing anything inside the motor back on. Call and request replacements. If need be have product support reach out to me via email.

                              Sorry for the inconvenience guys, but we'll make sure to make it right.
