Swiss001 here. Today, we're going to take it to the next level.
This is a turbofan engine, and it's no ordinary engine - this is the DM 119, the largest turbofan jet engine model on the internet. I'll give you my honest opinion.
It's time to build this level 5 difficulty jet engine - for 10 hours straight. Yes, that livestream ended up taking 11 hours.
Here's a photo of me looking through the manual and checking the box - it looks beautiful, and to be honest, these are the small parts we need. The good news is that you don't need any tools, as they are all included. We're going to start making some kind of compressor disc right away, I don't know, but we'll see.
We need to put on the small fan - after all, we're making a rotor. We have 32 parts. I think these are replacement parts, which probably makes sense. Yes, hour after hour, I kept making rotors, small compressors, and small turbo compressors.
The whole structure is made of metal, which is very comfortable to use. The manual is very good - in two languages: Chinese and English. The build took as long as it took me to build the Concorde, which took me over a week to build. But this one, I built in one session - you shouldn't do that. To be honest, I aged 10 years and turned into a vampire, which is great.
After assembling rotor by rotor, it was time to put everything together and make a real engine. The cool thing is that it has a motor in it - a small electric motor, so the model really spins. But when it came time to test the engine, I stumbled upon a problem.
I assembled the gearbox wrong. It was a bit complicated and fiddly, and I didn't follow the manual correctly. Maybe I should start working at the Boeing factory in Seattle.
But now, the engine really spins. To use it, flip the switch here. The engine starts to spin slowly and easily. There's a throttle here to increase the speed. Look at this speed and power! If you put your hand here, you can actually feel a little wind. Of course, it doesn't sound like a CFM 56 - there's no kerosene burning in the combustion chamber, and I don't think the aluminum parts can handle the heat. I might have died. But we do have sound when you press the power button here.
It didn't impress me too much, but that's okay. What really impressed me was the little window here - you can see all the gears turning. It's really fun. Another thing I like is that it's battery powered. It has a small 800 mAh battery that you charge with this 5V USB cable. But let me tell you... well, the battery is dead. Yeah, I've been driving it all day. For a permanent setup, it's better to leave it plugged in, but one battery charge is definitely enough to impress some people.
But this thing is very expensive - $1,000. The thing is, I don't think they can make it cheaper. We're talking about 1,000 metal parts that have to be made individually, which sounds like a lot of trouble and it can't be cheaper. You can buy more smaller models for a lower price
