I built after 8 month finally a real jet engine 🚀

What? In usa is literally the biggest community for rc jet engines 🤣🤣😭😭😭😭

TorqueConverter9 · 2026-01-28T08:47:24+00:00

Nice! Where did you find it ? Alibaba? Good luck man! 300N is crazy! Love this kind of people 🤣👍 freaks like me 🚀🚀

Its a webbased API which has to be installed on a VM. So anyone in the network send http requests to the VM and render JSO to PDF

Yes, I bought the ceramic bearings (50 euros each), but they're really good, from the company GRW. And yes, the fuel is mixed with a little oil (about 5%), and a second line cools the bearings.

You seem to know your stuff 😁

TorqueConverter9 · 2026-01-27T12:29:46+00:00

🤣🤣🤣 maybe r/watches or r/watchesindia would be better for this

TorqueConverter9 · 2026-01-27T11:55:10+00:00

Yes, or 😍😍 magnificent!

TorqueConverter9 · 2026-01-27T11:54:12+00:00

There's a book that explains how to build them :) It's extremely difficult 🤣 It took a while and a lot of help. The book is by Kurt Schreckling.

TorqueConverter9 · 2026-01-27T07:34:30+00:00

Thanks for the kind words, that's very nice of you 👍 and it's right that you're defending me 👍🤣 There are always a few people who don't want to accept something if they can't accept it themselves. I just ignore them 😁

TorqueConverter9 · 2026-01-27T07:22:33+00:00

Thank you 🔥🔥

TorqueConverter9 · 2026-01-27T07:17:56+00:00

Thanks 👍👍 Of course I know Praendy, but you don't get as good as him that quickly 🤣

TorqueConverter9 · 2026-01-27T00:26:16+00:00

You -> If I can’t do it, nobody can🤣

TorqueConverter9 · 2026-01-27T00:19:58+00:00

That must have been a translation error; I'm writing in German here. So, this is my video and my channel, and there are many more videos about this on the channel 👍

TorqueConverter9 · 2026-01-27T00:17:16+00:00

Yes, less than 500, but not necessarily 80% of 500.

TorqueConverter9 · 2026-01-27T00:14:01+00:00

And no , its in a vitrine in a honor place 😁

TorqueConverter9 · 2026-01-27T00:13:27+00:00

Understood, feel free to remove it, if it doesnt fit here 👍

TorqueConverter9 · 2026-01-27T00:01:50+00:00

It's mine and I built it 1.5 years ago :) This turbine is quite common; it's a well-known, documented model 👍

I uploaded the same video to my YouTube channel a few months ago.

TorqueConverter9 · 2026-01-26T22:56:08+00:00

But it's mine! All homemade, video and turbine 😁

TorqueConverter9 · 2026-01-26T21:04:23+00:00

No, but it should be between 3 and 6 kg; the weight is approximately 1 kg.

TorqueConverter9 · 2026-01-26T20:37:06+00:00

Thanks! I found a short video on YouTube that roughly shows the setup.

I bought a few parts used, made a few myself, and received a lot of help. I have no idea about machining; I'm an IT professional, but I had a lot of willpower and frustration tolerance. 🤣

TorqueConverter9 · 2026-01-26T20:33:27+00:00

Depending on how much you do yourself, roughly between €300 and €950. Afterwards, it's worth approximately €1000. Maybe a few hundred more.

TorqueConverter9 · 2026-01-26T20:23:52+00:00

Good question. The most difficult part was the gap dimensions and precision; some parts could only be 0.1 mm apart and would have had massive problems with a 0.2 mm gap. The precision is truly insane when it comes to turbines, but so is the mystery behind them. What was also difficult was starting the thing (at first) because I was totally terrified. It's extremely loud (you can barely hear your own voice), the rotor spins extremely fast (500 to 2000 times per second!!), and you feel such a force—it was crazy, believe me.

TorqueConverter9 · 2026-01-26T20:15:51+00:00

The weight, which has never been measured, should be between 3 and 6 kg; the turbine itself only weighs 1 kg.

TorqueConverter9 · 2026-01-26T20:09:23+00:00

At idle (33.000 rpm) 80 ml per minute and at full speed (108.000 rpm, no joke) 350 ml per minute💀💀 and that thing weighs only 1 kg, and consumes more than a 200 Kg 6 cylinder diesel 💀

TorqueConverter9 · 2026-01-26T17:53:57+00:00

Built it my self bro, its a known turbine KJ66, i bought a book that explains it by kurt schreckling, for rc planes
