Great first installment of "Engine Week". I really like the fact, that there are still companies like Jabiru, UL Power and a few others, who are still producing simple, dependable aircraft engines that people with average skills can work on and maintain.
Good engine. I used to overhaul the gen1 and 2’s. I remember helping out with the testing of the 8 cylinder jab fitted to a scaled replica spitfire mk24. Yes, that thing sounded very cool!
I have a Jabiru 3300 gen 2 in a kitfox series seven. It runs really smoothly. Nick & his staff are excellent. I would be happy to get a Gen 4 when my current engine times out. I would love to come to the class, but live too far away. I would buy a recording of the class if it were made available
After engine week I think we'll need a nice big PDF of all the available engines as of Q4 2024, with their specs, pricing, and a few basic notes on each.
I know a bunch of guys warm up the starter motor with a heat pack, or sit the kettle on it while they enjoy a coffee. It warmed it up enough to get a good start
@@Captndartynot really. I can think of other engines that have starting issues under different circumstances. In this instance, warming up the starter in cold conditions is a simple fix
The more I learn about turbofan jet engines and seeing this, the more it's obvious that comparable jet engines are much easier to make than even the relatively simple jabirus. Think about that. There are so many parts and so much mechanical friction in a piston engine, not to mention the propeller which is also part of the power plant. In a turbojet engine it's a single shaft with two fans in the simple case and the more desirable turbofan engine it's two shafts with at least 2 fans each. No mechanical contact anywhere other than the shaft ball bearings. It's really a psychological barrier more than anything because piston is a more relatable concept and a jet superficially seems kinda magical but it's really fairly simple, it's just very counter intuitive that blowing through a fan can be as efficient as a piston engine that's seemingly more disciplined about letting the pressure out. An Eclipse 550 is as fuel efficient or better than a Baron 58 despite going twice as fast with a bigger cabin. Again, think about that for a moment. And turbofan engines have been very possible since 1960. As have fiber composites. In Hill Helicopters latest video he shows one of the turbine blades in their 500HP turbine and it's little bigger than a thumbnail. The convoluted chambers can be 3D printed in one go these days with no effort. The blades can be CNC milled. Quality but conventional bearings will do. Stainless steel and inconel 625 can make a good jet engine and both are commercially available for human money. High strength stainless steel is dirt cheap, inconel more expensive around 45$/kg. But if the total engine weighs 15kg and only 40% is inconel, it's not all that much...
3D printing jet engine parts with no effort you say? Good luck. Compressor shaft speeds of 30-45,000 rpm require a heck of a “regular” bearing. How come the eclipse jet isn’t flying anywhere at under 25-30,000 ft and usually much higher? It isn’t just counterintuitive that turbine combustion isn’t as efficient, it is reality until quite high. If it were as easy as you propose, no one would still be using pistons.
@@itlodot you don't have to print all the parts, just the convoluted static parts. A shaft is relatively easy to make conventionally. Blades may also have to be machined for now. But 3D printing offers amazing complexity for all the routing, indeed it offers designs that aren't possible with traditional manufacture. All the plumbing running on a jet could be baked in. I wouldn't print a ball bearing either. But those are relatively easy to get. 3D printing lowers the barrier to entry decisively, even offers superior designs. Who in commercial aviation are still using pistons? I also had the intuition that turbines were inherently wasteful but surprise surprise, they can indeed match pistons even often exceed. A turbine used for power plants can be as high as 60% efficient. Your average V8 isn't. It's also quite telling that the world distance record of 40000km at 500km/h belongs to a simple off the shelf turbofan engine, the Williams FJ44-4. You know any piston planes with 40megameter range at 500km/h? at any altitude. Last I checked a Cessna 172 doesn't have the range of an Airbus A350ULR which flies 18000km. How much do you think you'd have to caress that piston engine to go 15x further? Just maybe we should have transitioned to jets in 1960s. The tragically poor state of the GA fleet is a hint that not everything is just right. Indeed Nasa attempted a 100m$ project around 2000 to get small jets for GA. Williams fukked it up. The Eclipse and Visionjet are direct products of that even though they fell short and crept in weight and price so never delivered on the premise. Did you know the Eclipse twin jet was originally targeted for a 500k$ retail price? which is half the price of a Cirrus SR22T If you think about it you may also realize that it's absurd that a balloon with an angry space heater on costs 4million dollars like vision jet does. it used to cost 2million but through economy of scale they managed to double the price and pass the savings onto you
I really appreciate your efforts! Could you help me with something unrelated: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). Could you explain how to move them to Binance?
it's 2025, these engines need a FADEC EFI option.. not saying that everyone has to get it, but as a nice plug and play option. until they do, I would not consider them viable when we have Rotax and UL Power available.
Exchange rate??? 1 USD has been flat all year at 1.50 AUD give or take 3 cents. There is nothing wrong with raising prices for market reasons, but no need to BS about it.

Super appreciate you putting these together! Such great info : )
I've ordered from Arion several times for my Jabiru engine and they provide great service.
Wow at last a decent interview.. Time to subscribe..
I love this conversation. "How it gets fuel". "How it gets electricity". "How it gets air". Yep, All good. Whoosh!
Good engine. I used to overhaul the gen1 and 2’s. I remember helping out with the testing of the 8 cylinder jab fitted to a scaled replica spitfire mk24. Yes, that thing sounded very cool!
I could do engine week twice a year man even if nothing changes its still cool

Did I hear correctly he said the prices are 25 000 USD and 20 000 USD?
@@RagingShrimp6716 minutes in, 20k & 25k and he’s saying he includes a lot of accessories
I was lucky enough to machine the first ever Gen 4s both 2200 and 3300’s at Jabiru.
I have 500 hours behind a jabiru 3300 1st gen. Good engine except it didn’t like to start below 50 deg F.

@@donwtsn zero excuse for an engine in 2024 to have starting problems 18° above freezing

Will the new mechanical fuel injection system be retrofittable to the present Gen 4"s?
Want a tip? Stop looking at the cameras.
Then it will be more like a conversation between you two! Much more natural.
I passed my pilot certificate test in a Jabiru aircraft ( in Australia) in 1998.
how much does an engine used in the cessna172 cost

Record the Engine class and sell the DVD for those that cannot come..

They may be good engines, but don’t hear or know to many people the run them.
