    I love your designs!
    Building the Supersprint was the most fun I had since I started 3D printing.
    Your designs are just AWESOME!
    And even your instructions are amazing!
    THX for your dedication!
    I'm still hoping M-Jet 30 compattible TPU Warrior...

      Thank you. Currently I have no time for the M-Jet 30 TPU Warrior version, sorry:( too many projects with priority.
      Right now the M-Jet 35 is on black friday sale for 28 USD, maybe you'd find it attractive

    for the bearings in the pump are you going for higher end specd or chinese stainless. I can find the smaller bearing with ceramic balls, but not the 5x19x6 one

      @@zviper I am using stainless bearings which I buy from european shops, I am not sure where they are manufactured originally.

      The "seed phrase" is your back up password. Combined with your wallet "adress" it is your account.
      Do not share your seed phrase with anyone ever ok ?

    Is your next video going to be a continuation of the video about the pump pressure and intake velocity? Have you made updates since that video to the pumps and why have you deleted it?

    • @mjetdevelopment
      @mjetdevelopment  26 วันที่ผ่านมา +3

      Yes, you are right, I hid the video.
      After I released it, I had some more thought around it. Right now the M-Jet Development is my only side job while I am studying. I really like it and I would like to continue. In order to keep my position on the market and my income, I can no longer give away all of my knowledge and methods. Anyone who comes to design jet pumps after me can copy what I do without having to spend those 5 years to figure it out as I did.
      As you can see from my videos, I like to share stuff. However, by doing it, at this point I am just putting my job in danger. Therefore I need to find a balance between sharing everything and keeping some tricks for myself. I will continue to share the results of my work; probably no longer everything which led to them.
      Thanks for understanding.

    Hello 👍This boat is really good work. I would be interested in doing it and I see that the files are free too!!! Do we need to add the motor additionally?

    • @mjetdevelopment
      @mjetdevelopment  28 วันที่ผ่านมา

      By "motor", do you mean the jet pump?
      The files for the Ragnarok hull are free: www.cgtrader.com/free-3d-print-models/hobby-diy/other/ragnarok-3d-printable-rc-jetsprint-boat
      The files for the jet pumps need to be purchased. Currently, you can choose between the M-Jet 35 (more powerful) and M-Jet 30 (cheaper).

    Awesome! I’m working on getting my ragnarok trimmed out, it would always spin out in turns but hoping the larger fins will make it perfect! What size fins do you use?

    • @mjetdevelopment
      @mjetdevelopment  28 วันที่ผ่านมา

      In this video, I used Mega 25 turn fins. I managed to make the hull stable and stop any hopping, however I am still not fully happy with the cornering, it spins out more than I'd like. Tuning the handling takes time and requires testing many different combinations of all parts.

      @@mjetdevelopment regarding cornering: have you tried making a progressive trim for the nozzle with +2.5 at the center and +10 at the very edges? I am thinking about traditional surfboards, when surfers want to turn on a dime they move all their body weight to the stern (where fins are) and push hard (I used to practice windsurf a while ago, same principle)

      The Castle is expensive indeed. I am absolutely amazed by both its performance and its advanced features, but to get a boat running there are cheaper options, for example Hobbywing 180A or Spektrum Smart Marine 160A (keep in mind the motor I used in the video pulls over 170A on full throttle so it is always up to you if you trust the ESC can handle it).
