I recently saw a video visit of the Rotax snowmobile engine assembly line. I did not know they made aircraft engines. Thanks for the great video!

I was a Rotax manganic and visited that factory, it was a great experience.

Nice video. Well made. Thanks for no music. You answered more questions about Rotax than I knew I had.

What an excellent and well presented video! Thanks so much for not having background music!!! Once the engines go into the GA market there are a lot of wild card variables and would want specific data regarding failures to include disassembly by qualified people. Thanks for the video.

Superb video, sir! The Rotax 912ULS in my 2007 Sting LSA is coming up on 3,000 hrs now, without a major mechanical hiccup! My leak-down compression numbers (84-86/87) and take-off performance values are as good as they were at 200 hrs! I'll be buying a new engine--someday.

Baie Dankie/ Merci Beaucoup Mick B for this good video. Rotax is very fine engine. Their factory ppl looks very professional. I was looking for a Rotax Diesel.

Wow. Impressive video. Great work.

Thanks so much! As an olde school VW, & Porche mechanic, I've wondered what the difference was between them, and the Rotax, and if it's air, or water cooled? So, it looks almost identical to the air-cooled engines I work on, other than the water cooled heads, and judging from the fins on the cylinders, I'm gonna call this 1. A hybrid, and 2. An engine I can't wait to work on, and maintain. I LOVE the simple design 😁✌

Crank in pieces is old motorcycle technology, which is not used by bikes anymore. Last bikes, which used this design, Kawasaki KZ1000 had a problem of crank pieces turning against each other. To overcome the problem crank pieces were welded together by repair shops after assembly. Honda was the first smart bike manufacturer which stopped using this design and started using one-piece automotive style cranks.

Here in Australia, I am having lessons in a foxbat (rotax engine) a great plane to fly, but I have always been a bit of a nervous flyer. Then I watched this clip, and I felt a lot better, then I read stancurtins comments, and I felt a bit nervous again, then I read jason ensmingers comments and I felt a bit better again. Surely the rotax has to be safer than an older lycoming in a 1970s 152, which I had my first lesson in.

Wow, I want a Rotax hat.

I had 8 engine outs in 6 years of flying ultralights with Rotax. And, that was not uncommon on the field where I tied down (which had 150 untralights). Even the factory demo planes stuck several pistons a year. The care and assembly looks good here, but I've never seen that kind of failure rate in GA engines. I've seen a lot of people claiming the reliability is comparable, but that certainly was not my experience. As a pilot, I'd strongly advise a kit builder to really ask around and research an engine before they decide on it. And, always keep where you're gonna land in sight. :-)

Are you referring to 2 strokes or 4 stroke engines. Failures in the 912 and 914 series (4 strokes) in factory mounted LSAs are very very rare. You might see a few failures in E-ABs mostly due to builders mistakes.

@stancurtin

9 жыл бұрын

Yes. I flew several different 2 stroke Rotax engines in different ultralights (MX and Phantom). Because failure rates were so high, we accepted it as part of ultralight flying. We did all the recommended maintenance and used the best oil we could. But engine outs remained routine with Rotax. Kawasaki engines were far more reliable, but do to liability, they stopped making them available. I have no animosity toward Rotax, but it will take quite some years of good service records before I'd be convinced they have produced a truly airworthy engine. But I hope they have/do!

$18,000 + for a 1350cc 912 ULS motor with a single speed gearbox. How does Yamaha build a 1500cc complete snowmobile for less money? There's a reason there are a lot of Experimental aircraft built with VW air cooled motors with thrust bearings, and no gearbox, for 1/3rd the price, or less. 2000 hours for a motor isn't much life. I wish VW would build motors for experimental aircraft, then we'd get some true economies of scale. VW built TDI turbo diesel motors, capable of 130-140 HP with planned motor life of 25,000 hours.

I bet you can put these in a small hot rod, like a Volkswagen Type 1, Karmann Ghia, Fiat 500, or something similar. You need an adapter plate for the transaxle, a clutch and maybe a car flywheel. The turbocharged ones would make a lightweight car really shift like a rocket and get its skirts up quicker than a female flasher.

Can we use BLDC hubmotor instead of Rotax engine..?

Thanks Paul. Well done video. My main takeaway from this is that there is NO WAY an average owner is going to be able to do anything significant to the engine with a failure, unlike a Lycoming or Continental owner. All the special jigs for assembly show not a lot of consideration down the line. It is similar to car builders who do not take into consideration doing engine repairs. A car is GOING to have a internal part fail or get crashed and need repairs. Goes for aircraft engines too. I hate that cars are built by putting the engine on a frame and dropping the body onto it. Rotax may make pretty, accurate, reliable engines, but if you need special tools and jigs to reassemble it, another manufacturer will win in the long run. I subscribe to KitPlanes: what EAA SportPilot >SHOULD< be.

@randyvanvliet226

Same crap with German made cars... Once the motor is screwed together at the factory, it's never the same if technicians have to pull the heads for some sort of failure, or sticky lifters, etc. There's a very good reason when something fails on german engines, you get a new crate engine shipped from the Motherland to drop in. The QC is just not there with current technicians being able to keep assembly QC levels necessary, without the factory jigs.

Rotax has the best power to weight ratio of any proven aircraft engine in production. Thus for light sport and many experimental light planes it has a virtual monopoly. Many companies have tried t compete and largely failed. The only thing comes close to their reliability would be 1940's tractor technology based Lycoming and Continental aircraft engines. They are significantly heavier and direct drive so for light planes they are not suitable. Up to 90 to 120 pounds heavier for the same HP and with same TBO
