Hi, since I can´t find any time to complete my project, I´m selling now all the components to make one. 4 x 53mm Youngster Jet units. 500€ per pair (so 250 each) 4 x Surpass Hobby Motors (the same youngster has in his jet surfboard and Kayak) 70€ Each 300A 16S ESC 120 €

Hi, if someone is interested, I am selling my 53mm Jet drives that I bought from Youngster jets. Awesome jets with lots of power. By any interest, PM me :)

Hi everyone. Does someone already noticed the LCB technology? https://www.prnewswire.com/news-releases/prologium-technology-and-weltmeister-will-co-produce-the-first-ev-in-the-world-which-adopts-next-generation-lithium-ceramic-battery-300545258.html Sadly, the website of the company, prologium...

30 cm seems quite long to me. Did you also twist the battery to esc cabels? Can´t see it in the pic of your board. Maybe that could help already solving a bit of the mistery...

Hi Srn, With what battery configuration did you go btw?

Hi Fabian. Can you add some pictures of that bottle system? I kinda didn't understand what you men with that. :oops: :P

Hi Srn. I would do it like in the image I attached you. For the dirt I would put a tank filter like the one used in nitro rc cars. link: https://www.ebay.de/itm/L11517-1-5-Mas-Rc-Nitro-Lokomotive-Kleiner-Inline-Legierung-Fett-Benzin-Filter/332728893087?hash=item4d782ffe9f:g:JPwAAOSw5cNYXTti...

Also, I saw that you are going for a gearbox build. That's actually the way I was going too before I noticed that at that rpm range, the gearbox is going to be really really hot. Did you already think how to cool the gears? Cheers

Would be interesting to build a flumen. So you actually could measure the impeller effency, the torque, amps, rpm and also optimize the nozzle and stator geometry. have a look at this: http://efoil.builders/t/home-made-flume/794

Do you also need to change your battery pack or can it deliver 200 A cont.?

Chris, how is it going? Did you push the motor to its limits already?

Yeah... can imagine that. Did you take measurements of the ESC temperature and Ampere? Would be interesting to know if the ESC can really handle the 300 A. And also see if nothink burns out :D

https://www.youtube.com/watch?v=-sIVpOLYoqg maybe this? Also, how do you think about using this...

Good job dude! That look's AWSOME!! :D So I'm thinking to sell my Lehner and buy your same motor.. cheaper and work well too apparently... :)

Well, let's hope for the best! It also seems to me that your jet unit is kinda going underwater. Doesn't that lead to thrust losses? Cheers
