Just getting started on the M-Jet. Ordering all my parts first then study the build process more closely. Wondering about the coupler you used. Is it flexible? If it is where did you find it? Looks like a well thought out design, can tell you put in a lot of time. Well done.
Thanks! My coupler is flexible, I used a KMB coupler and drilled through the 4mm hole with 5mm bit: kehrer-modellbau.de/en/KMB-JET28-Rev.-3/KMB-JET28-parts/KMB-high-load-shaft-coupling-OE-4-mm-OE-5-mm You can use any solid coupler as well. I used the flexible one just because I had one at the moment.
Well done! I've thought about doing a boat this size for a long time, the hardware is just so much cheaper, esp at 24 or 40amps. Good job. Nice lid design. I've just got too busy with work to do anything like this. Will this one go up on CGTrader? Just thinking.. got some drivers and a model engine + exhaust that'd be perfect to print for on this lid, maybe that can go together as a bundle. Would look awesome.
Thanks, nice to see you here :D It still has a long way to go, but if further tests are successful, it will probably go on CGTrader as well. I have seen your drivers and engine before and I really like it, I was thinking about doing something for this boat but I dont have the designing skills for this type of things. How do you mean that it could go together as a bundle? Obviously I dont want to take any advantage of your own work. Otherwise I really like this idea, maybe we could discuss this later, as (if) I go on with this project.
Thanks! The development is finished now, STLs are avaiable for purchase here: www.cgtrader.com/3d-print-models/hobby-diy/other/m-jet-sprint-3d-printable-rc-jetsprint-boat-model
I used a regular tube glue (not superglue), but it holds well and prevents leaks because there is a lip for the glue. Not just 2 surfaces aganist each other but a 4mm lip parallel with the hull surface.
Thanks. I use the ride plate for the same effect, with the benefit of (in my experience) better cornering. I might try the nozzle angle if the ride plate does not work in the next version.
It was just some foam to not damage the boat or the pool if I crash. The nose was rising up a lot, but that is normal at lower speeds. When accelerating, at first the nose goes up and then the stern rises as well. The next version is in the works, we will see if I am right, but this is my experience.
Hi Stefan. Really amazing what you do with the jet and the boat. Can you please help me with the parts? I'm really beginner with this topic. I want to buy your jet stl's and print it but I don't really now the other parts (esc, motor, receiver ...). Could you help me to buy the right/good parts? I would have just a few question. If you can add me on Facebook or I can write it here too. Thanks!
Hi, glad to see you like it. I am not sure if you are talking about this boat or the M-Jet pump (th-cam.com/video/XJ6AGuZhZ0Q/w-d-xo.html). The boat in this video is in development and the files are not avaiable yet. If you are talking about the M-Jet pump, you will need to build or buy a hull for it yourself. For the other parts, I recommend hobbyking.com for the electronics (esc, motor, transmitter and receiver, batteries, servo). You might be able to get the other hardware (bearings, shafts, o-rings, screws) in a local hobby store, but if not, you will find it for example on Amazon. A guideline for what exactly you should buy is in the M-Jet manual - if you have any further specific questions, feel free to ask here again. Good luck!
@@mjetdevelopment Hi. Thank you for your reply. Could you advise me an ESC + motor (for 3s lipo) from the hobbyking.com which csn handle your jet system and would be good enough for a bait boat? (So I am not interested that much in the speed part but want to build good and reliable bait boat for fishing and hobby porpuses.)
@@GyulaD Great! I recommend this motor, which I use myself (on 4s): hobbyking.com/en_us/turnigy-aquastar-3660-1700kv-water-cooled-brushless-motor.html And this esc: hobbyking.com/en_us/turnigy-rc-boat-esc-120a.html?queryID=e548721ff4cf287742b0f7bf2488603b&objectID=73854&indexName=hbk_live_magento_en_us_products In addition, this is a good servo If you also needed to pick one: hobbyking.com/en_us/hobbykingtm-hk15288a-analog-servo-bb-mg-9kg-0-20sec-51g.html?queryID=522ba412fc551215954d340c0d3b57dd&objectID=38568&indexName=hbk_live_magento_en_us_products
Wow! I am so impressed with this. You must be very happy with the result. Probably the neatest thing I'm seen printed yet! Liked and subscribed 👍
Just printed your M jet motor in a 60mm size configuration things a beast
To je ozaj krása! Nečakal som komoru na prevracanie. Ja som práve dokončil tmelenie kopyta (3D tlačené) na moje rýchlostné mono. Cez víkend leštím.
beautiful! today i got the 3660 motor for the big one!

@@mjetdevelopment I was thinking we decide on an amount and share the earnings? Just an idea..
That's one of the best 3d print jet drive projects I've seen. Well done! Plan to share the files at any stage?

Hi. did you use superglue for the hull parts? do the parts bond well enough to prevent water leaking inside? thanx
I used a regular tube glue (not superglue), but it holds well and prevents leaks because there is a lip for the glue. Not just 2 surfaces aganist each other but a 4mm lip parallel with the hull surface.
Nice, want to build one myself, inspired by you, how much wheight can IT carry ?
Hi, my boat ended up weighting about 1200g and it cannot carry much more.
@@mjetdevelopment Thanks 👍
Hello. Is it also possible to print with the ender 3. In terms of size
Yes!
very cool project, i would angle the thruster a little bit down, so it don't pull the nose out of the water.
Thanks. I use the ride plate for the same effect, with the benefit of (in my experience) better cornering. I might try the nozzle angle if the ride plate does not work in the next version.
what was the part infront of it when you pool tested it? i thought it was weight, cause it comes up prty hard without it.
hope to see more of it.

Will you be selling these? They look cool asf
I am selling the files, you can check my video "M-Jet Sprint Release":)
Hi
Can you send me the 3D printer file by e-mail?
Any files?
Not yet, it is in development.
