The M-Jet 35 development has been finished! Buy the files here and make your boat fly: www.cgtrader.com/3d-print-models/hobby-diy/other/m-jet-35-3d-printable-jet-pump-for-rc-boats
This is just a quick update, I got impatient so I decided to install the M-Jet 35 into an old hull I built 3 years ago, before I start building a good one. I expected it would hopp and dont worry guys, I know how this can be fixed. But the hull is too small anyway so I will start building a proper 50cm carbon fiber sprint hull soon. Yeah and the pump does not leak at all! Credits to my gf for shooting this video:)
Always fun to make a boat jump out of the water from a dead-stop! It seems your spaghetti-nozzle has good trust! Looking forward to see this pump in a hull, which will stay on the surface of the water!
The shape of the hull is bad, it has too small "delta" in front of the intake in a too sharp angle, it is not wide enough and CG is way too far in the back. Actually this hull hopped even with the previous ooold jet on low power I had in it. Hopping can be fixed by adding/increasing the length of a ride plate, or trimming the nozzle downwards so that the stream pushes the rear upwards.

This is a good showcase of your pump priming

Thing will absolutely rip in a proper hull! Can't wait to see some creek runs!
Finally some nice cheat for my rock-skipping career, can't wait to try it on my pebble. Good work Stýv❤️
That is a ridiculous amount of power for that tiny boat!
It is, haha. Its just a quick test before I build a proper hull
It reminds me of skipping a rock. Is it hopping like that because it has too much power or is it something to do with the shape of the hull?
