I have an incredible river to run on. Next step wil be finding or modifying a hull that self rights itself, anybody have any hulls they could recommend? I have a 24" shallow v I could modify but it would be nice to just buy a hull. Thanks, Jeff
      Hi jeff, postage will be $15 , pm me your particulars and we can go from there.
      Regards Mick

        Thanks Mickie, I will be placing the order as soon as I can. What would you consider to be the best motor choice for a 24" mono. Its been awhile since it was discussed and you have done a lot of testing since. I will be moving it into one of your hulls eventually as well. Would you consider them to be q gooe candidate for a flood chamber to make self righting? It's really a must for where I will be running it and would appreciate your thoughts. I was thinking around 1600-1800kv on 4s but I will purchase whatever you recommend. Thankw again, I realize thiw has been covered already but thought I would ask in case your thoughs have changed with further testing and I don't want to over power things. I have done a lot of reading on jet drives since I first saw this posting, your drive is in a class of its own and can't be compared to the others as they seem to be some kind of compromise rather than a purpose built jet drive and will be money well spent as far as I am concerned. Great job!

          Hi Jeff, thankyou for the king words, it is refreshing to hear all that.
          Mate, any 40mm motor around the 1800Kv mark is perfect on 4s lipo, I will not go into particular motors as everyone has their own favourites.
          Why go with a flood chamber when you may be able to get away with some lead weights along the keel, not that I have tried it but in theory it should work, maybe someone else can chime in here ......
          I was thinking on still down the track doing ABS hulls for all the guys who want to go stream bashing, just haven't fully looked into it yet...
          Regards Mick

            Thanks for the motor info. The lead weights sound like a good idea. I am leaning towards a flood chamber though because I could easily loose the boat if it doesn't right itself everytime. I would still use a fiberglass hull though, a little kevlar on the outside and it would be perfect for the river here. Great rapids to play in with a properly set up boat!

              Hey Mick. A few questions:
              • When do you think the modified hulls will be available?
              • I noticed you need two servo's. Is that for steering and trim? What channel is the 2nd servo running off?
              • How are you sealing the hatch?

                hi rick,
                i am hoping to have the molds done in a week or so , i just need to make sure that there is no more mods needed to the hull before i release them. Hoping to be doing the next run this week, then if all good i will redo the bottom mold x 2.
                You are right about 2 servos, 1 for steering and one for trim, you might get away with fixing the trim with a turnbuckle and adjusting it on the bank, i have it on the Aux channel on my radio mixed in with the steering, this way i can adjust the trim whilst it is running and i have it so when i put in a steering input it points the nozzel down a few degrees putting the nose back in the water to make a smoothero tighter turn..
                The hatch mounts over a lip, there is also a channel running around it exiting out the back, i will also running some neoprene around the inside lip for some more insurance. so far this works well, i guess you could also run the tape around it too ...
                hope this answers your questions.
                warm regards mick

                  It does. The Steering/Aux channel mixing is new to me so I'm not quite sure how that works, but I do have a 3 channel radio. I do like the idea of sliding through turns. It'll remind me of my old SeaDoo Speedster. How hard would it be to fix the trim into position?

                    Hi rick, shouldn't be too hard, you just need a small turnbuckle and make a small L bracket to fix onto the transom, even if you do not mix it into the steering, it really is quite handy being able to adjust the trim as you go.

                      I just got my kit from Mick today in the mail.
                      I opened everything up and all the parts look great!
                      This is an awesome kit and I recommend it to anyone wanting to get a jet unit or a jet boat.
                      I look forward to building this 1 soon as I can find some time!

                        Jeff, you have to share this build-up... When the dust settles around here with repairs and SAW builds and trying to build boats for the Nats (phew!), I'd love to build a fun boat like this!

                          I most definitely will.
                          I am planning to run a proboat 1500kv motor to see what it will do on 4s.
                          Will most likely be using the 60amp esc I got from you.
                          Thinking I could also run it on on 5s?
                          What do you think?

                          Maybe you have another 1800kv motor laying around I could use???!

                          Should be a fun 1 no doubt about it.
                          Just a neat little boat and great jet unit.

                          I also plan to put a full wrap on it and make it look super official.

                          Probably be a month or so till I can get on it as I have other projects going.

                            Hi guys,
                            Thanks Jeff for your kind words.
                            Just a little update, I am doing the final wets and and polish on the molds, should be ready to lay up the first few modified hulls out tomorrow, my apologies for the delay guys.
                            On another note, the cad file for the Marathon river race jet boat hulls is about 3/4 done, so I should be able to rout out the plugs in a few weeks. When I get back to the computer I will post some pics of the real boat I'm scaling from so you all know what I'm talking about.
                            I will have the next video of the modded jetsprint, uploaded inn a few days.
                            Thankyou for everyones patience with me.
                            Regards mick

                              Here is todays run guys, this is with the lower lifting strake removed, pretty sure I need to move the C of G forward more.


                              Take care

                                It sure seems nice and responsive, the hopping is something else though. Where have you got the center of gravity set on the last video?
