- Rotax is well known for its line of aircraft engines, but these are just a small part of the company's engine-manufacturing business. Last summer, AVweb's Paul Bertorelli visited the factory and produced this engaging video of how the company builds its aircraft engines.
Авто/Мото
We must not forget that thanks to this company, sports aviation has become accessible to people with average property status, and the quality is at a high level. Thanks AVweb.
Ambassador Bertorelli pulls off more awesomness.
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!
They don’t really! Lol these are modified snowmobile engines.
Literally had a A&P tell me it was an unsafe engine and I should sell my plane.
This and Rotax has horrible support, sky high parts prices, built in design flaws that you will never be able to fix. If you want pain buy a Rotax
Terrific motors. Our fleet has had great experience with them for 20 yrs.
Talked to a guy who had put 1,800 hours on a Rotax all over the country. Burn was a little over 3 gph......great engines.........
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.
Excellent video. Clear and to the point without any unnecessary distractions. Thank you
I was a Rotax manganic and visited that factory, it was a great experience.
My BMW F650GS Dakar has a Rotax 650 in it. It makes some weird noises, but it's the only thing on the bike that isn't falling apart after 70,000 miles.
Have a 2009 Aprilia Tuono 1000R Bike with a V-Twin Rotax Engine that feels like it could run forever. Refined company doing quality work, 18,000 miles and still runs beautifully.
As ever Paul gives an information dense presentation with an industry leading high signal to noise ratio.
Keep it up!
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 😁✌
They have watercooled heads on the 4 stroke donks
I bet you can put the turbocharged ones in a Volkswagen or old Fiat 500.
I think there’s a VW bus in OZ with either a jabiru or a rotax in it.
What a wonderful and well-crafted presentation!
This was an excellent production! Thanks for putting this together and sharing :)
i dont mean to be offtopic but does someone know of a trick to log back into an Instagram account..?
I was stupid forgot my login password. I would love any tips you can offer me
@Phoenix Mekhi instablaster =)
@Brady Torin thanks so much for your reply. I got to the site on google and I'm in the hacking process atm.
Looks like it's gonna take quite some time so I will reply here later with my results.
@Brady Torin it worked and I now got access to my account again. I am so happy!
Thanks so much you saved my account!
@Phoenix Mekhi No problem :D
I had a Foxbat amphibian with the Rotax 912- a wonderful motor for a seaplane, constant temperature , you could do splash and goes all day and it did not miss a beat.
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.
I enjoyed this video. Please make more like it :-)
It's like watching "How It's Made".

A Totally Excellent Video. Thanks for the Insight into the Factory ( :

How many recalls Does Toyota have?
The car company that on Wednesday announced it was recalling 1.9 million Prius vehicles worldwide was the U.S. leader in recalls last year. The company recalled 5.3 million vehicles in 2013, more than No. 2 Chrysler, with 4.7 million, and nearly twice as many as No. 3 Honda, with 2.8 million.
Just a sample....VW has beaten Toyota as the biggest seller of cars worldwide now...There's a reason.
Wow. Impressive video. Great work.
Thanks . We had the best Experience with Rotax so far !!! But with others we didn't . Jabiru failed when the valve seats jumped out , and the Arrow failed with the carburators and fuel pump . That's why we went back 2 Rotax !!! ! !!!
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.
Great video production! I love my Rotax 912 ULS--which has never had so much as a "burp" in 1,700 hours of flying! I've found that most "problems" arise when Lycoming and Continental "know-it-alls" think they 'know it all,' about servicing the Rotax engine. That's when problems begin.
AMENNN !!! ! !!!
Less surprises in a four than a two stroke engine.
Not necessarry ...
The statistics are on Stephen Bonin's side there Kopronko.
Be great if the new generation of light, clean and reliable 2 strokes that are hinted at every so often were to happen 'tho.
Airplane engines are small bore, but long stroke, right?
Single cam? And carburetor? Seems very interesting, basic but functional I guess. I’m more of a car person but this is fascinating.
The best report I ha seen so far !
Great Video. Very enlightening.
WOW, Outstanding quality! Thank you so much for this great information.
BEAUTIFUL WORK
Rotax vends a prix d'or des moteurs et ça ne les empêchent pas d'avoir des problèmes de traitement thermique sur les tiges de culbuteur, des flotteurs qui coulent et des régulateurs qui grillent.
Ils ont de la chance de ne pas avoir de concurrent.
I have both , 2-strokes and 4 strokes---never had even a burp out of mine along with others in our flight park. Only engine outs was were due to lack of fuel...
That's not supposed to happen you know...
Old school for the best result!
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.
Paul Wiles Speedway
Thanks for sharing the swinging level of confidence from the world of ultralight.
I wouldn't say they are more reliable. lycomings most reliable engine io360l2a in the newer 172 s is absolutely more reliable and less complex than most rotax engines.
The Lycoming is definitely more reliable. Regardless of age the engines are generally overhauled around every 2000-2500hrs depending how far your willing to stretch the interval.
Forgot what the overhaul intervals are on Rotax engines, but if I remember correct it was somewhere around 1200-1500hrs.
A friends 912 in his kitfox has over 2300hrs and is still going strong..
Nice factory, but the engines cost way too damn much
Can we use BLDC hubmotor instead of Rotax engine..?
good and very informative. ...
Why isn't the upper half of the gearbox housing 'web reinforced' to the crank case for strength?
I think you got the harmonic damper and overload clutch back to front.
In Australia, these are regarded as ......"Bavarian Time Bombs"........meaning that you never know when they will go "off".....!
That's the same country that makes the Jabiru. Meaning, you never know if it will start. In America it means. keep that POS out of my airplane.
gentlemen, rotax, thanks you.
"Economy of scale....." Yeah, right. You can do two things with that "economy": Lower prices, or higher profits. It's pretty obvious which way Rotax chose to go. Those things are absurdly expensive.
$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.
Supply and demand gentlemen. Why is a 4 cylinder Lycoming 50,ooo plus Australian dollars?
Rotax… such bad engines. Most people don’t realize they are virtually unknown by most mechanics and difficult to fix and keep running properly.
impresionante felicitaciones por algo son los mejores !!!
Ill take that first one with the purple hair highlighter.
👏👏👏👏👏👏Spectacular!❤️
Just curious. Was this video actually just a group of images from a magazine with a narrator reading the article? Asking for a friend..
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.
Wow, I want a Rotax hat.
I wish Rotax made a two stroke for Powered Paragliding. Powerful and light.
Skydrive (uk) are a Rotax dealer but for the lightest engines seem to be selling (Italian) Cisco 2 strokes.
I know little about them other than they exist, but it might be of interest to you as a start point Stanley?
Trust me you don’t wish this. Rotax are awful. If they made this engine it would cost you an arm and leg and would have more problems than a Chevy
good job
ROTAX ENGINES ARE EXPENSIVE BUT I TRUST THEM. SPENT MANY A HOUR BEHIND ONE IN THE AIR
I’d like to see the written text and sign off for the assembly of the aircraft engines.
Well done
this is an awesome video , thank you ! Do the US Military drone engines get made here too ?
Kevin Olesik No
Love how you get into ever detail great video!
I don't know if using Rotax in aircraft is a good idea. I may trust it in a brush cutter though.
Not safe for aircraft. It’s essentially a skido engine. Very poorly engineered
always thought cause it wasnt a big major name and went on lsa airplanes it was sub par quality glad to see this and know they are just as good and can feel better knowing its a good powerplant
If you look at failure rate(failures per units operating), they are as good or better than Lycoming. This coming from a Lycoming owner.
The US military uses the 914 on the Predator drones.
No! the US is responsible for murdering civilians.....as they say guns don't kill people, people kill people.
Very cool
Rotax - owned by BRP - Bombardier of Canada...
Modern factory for ancient engines
Good👍
This was very interesting and...very impressive. I've got a little bit of time in a Flight Design. The Rotax start and Rotax shutdown seems so weird at first.
Does anyone know about rotax factory or shop engines in the US.? Im from Nebraska thanks..
+felix romero Move to Austria!
@@Crazyhero-zi6yt wish i could
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.
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!
From my experience, most of these engines used on aircraft are not certified for aircraft and are "Subject to sudden stoppages". This does not mean they are not reliable, but they cannot be guaranteed for aircraft safety for those models.

I hate aircraft engines, stuck in the 1950s. Afraid of innovation, that goes for every type of engine, Lycoming, rotax, etc. The mentality if it ain't broke, don't fix it. Use bmw, 4 stroke, straight line 4, motorcycle engines, modern, better engines.
Something is weird with the voiceover audio, like constant buffer dropouts....or my computer is on the fritz....
Hi what is the price of this engine pls
Too bad the cost of the engines are effectively taking aviation far from the grasp of the hobbiest.
And bring back the 503.........dcdi
This engine is still WAY less expensive than a Lycoming or a Continental...
@@ibgarrett Maybe. A Continental Titan 340 costs about $29k and produces about 180HP. A Lycoming O-320 has a price tag of $47K and develops 160HP, Rotax's 915iS costs about $39k and develops 141HP. I'm not sure I'd say its "way less expensive" but merely on par with their competitors. To Rowdy Flyer1903 original point, I do agree the price does place it outside the reasonable expectation of hobbyist, especially when you consider the $39,000+tax price tag is for the non-certified version of the engine.
I just can't see where the value is for that engine to be $39K... I mean they're building entire cars for half that price
but just imagine the profits this company is garnering from the airplane engine line. I can't imagine this costing any more than 10k for Rotax to make.. However, it must have cost a lot of money for upfront development costs, for example. Looking at their fiscal report it appears lumping all the different types of engines and vehicles together, they are running at least 20% profit. So, can't say what kinds of profits specifically, but still interesting.

Lástima que siendo el idioma español el segundo más hablado a nivel mundial, no tengamos una traducción para los que no somos hábiles en otro idioma, pero si consumimos productos ROTAX
Please detail this engine parchasing this engine how
Very interesting video!
Great report, Paul. No mmbo jumbo like from Dan Johnson.
Dan Johnson is a Prince in aviation. Delete this stupid comment.
could AVWEB possibly crank the video settings up a notch past a blurry eyed 144???
I can view it in 1080. Maybe you have to wait a bit
It was loaded in 1080p and I can view it at this res. Check the setting and you should be able to as well.
AVweb I had no problem at 1080p.
You chime in too bitch....but don't bother thanking people for helping you with your fuck up??.....ya fucking mook.
How much does is cost
I don't see the gold plating in them anywhere, that justifies thier price...
You sound like you have never owned a Rotax motor? they don't come any better.
@@MrKdr500 Literally any modern automotive engine is better.
Philly Cheese Take Please. Take any automotive engine and run it at 5,500 RPM for 2,000 hours straight. I’ll stick with Rotax thanks.
@@andrewmorris3479 Water-cooled derivations of car engines have about a 30% TBO advantage on similar Rotax models, and they also consume less fuel.
It's simply stupid to suggest that Rotax knows how to build better engines than Toyota, or Yamaha, or VW, or any major car company. The only reason they don't swoop in and put Rotax out of business is because they have too much common sense to enter the aviation industry.
Philly Cheese Take But a car engine doesn’t run at 5,500 RPM continuous, that’s my point. I’d want a lot of testing done before throwing one in an airplane.
Thanks ice
Good ole Pole Burrrburrrally
very nice rotex
I want to buy I'm from Thailand
What does one of these basic model engines cost (USD) ?
Rotax doesn't have a USD cost. It's cost is measured in Kidneys.
$15000 for 80 HP Rotax 912UL. These are aircraft engines. This video is meant to be addressed to aviation audience. The high compression 912ULS 100 HP is $18500, the Rotax 912iS fuel injected with redundant ECU system 100 HP is $22000 and Rotax 914UL turbo charged Carb one 115HP is $30000 and the newest Rotax 915iS redundant fuel injected turbo 141 HP one is $38000. 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
Is ge prat and Witney rolce royce the bigest manufacturer of airplane engines
why they not use lots of gaskets?
Sandy Telfer
The machining makes them irrelevant. They're essentially using a liquid gasket to get a complete seal. Olde school, air-cooled VW, and Porche engines are very similar. Just newer electronics(ignition), and a water cooled head✌
I want to work there now.
We could make my two cycle 'HOPE' {hydrogen oxygen piston engines} that exhaust pure water, have super supercharging, AND can run under water and into space.
What did Rotax say when you approached them with a properly crafted, professional proposal and running prototypes? How many do you currently manufacture? What are their dyno stats compared with existing systems? Where is your website? If your design is proven then demonstrate it and have neutral third party labs test examples.
At $23,611.00 it is over priced as hell for a sport engine!
*****
100% agreed and you don't have the extra weight of water and radiator . I my self use a EA-81 stratus engine making 100hp at the cost of $4,000 bucks to rebuild, I Still have to deal with water though!
Shawn Huffman I wonder how my 5.7 hemi would do in a rv-7. It might be a bit big, but I bet it would haul ass!
Shawn Huffman and hell if worst comes to worst, just jump out of the damn thing. I’m sure there will be plenty of money left over for a decent bailout rig 😎
but they too heavy. a 200hp aircraft engine weight sometime less than 250lbs while a car engine weight over 400lbs
You get a brand-new Lycoming for that
cost o price of rota 915 motor:?
$37,000 USD.
thinking ill go with a kawasaki 440 instead.
cost of Rotax 915 engine???
i wanna to purchase it,
over 30k
Study Mensa $37,000 USD.
👍
Props for using grams, and not something idiotic like rocks or stones.
the near future are electric aircraft engines, less maintence, costs less per flight hour
Batteries are heavy, kinda like your eyelids.
EASA Emergency Airworthiness Directive No - 2017 - 0101 - E - 9 June 2017 (Rotax 912 engines)
Applies to 912 iSc2 & iSc3 engines
Ignition house sealing plugs have been found improperly installed.
BRP Rotax has determined the population of stator assemblies and ignition housings that may be affected.
This condition, if not detected and corrected, may lead to oil leakage, with consequent loss of
lubrication, in flight engine shutdown and forced landing ...........
Which just goes to show - You can have world class QA and still something can slip through the net.
If you have an iSc series motor you'd better get it checked.
In the last 4 years there have been a flood of Service Bulletins on the 912. Mainly defective parts but also incorrect assembly.
Dude said Skadoo lol
hOW...ARE THE RODS ONE PIECE?
Same way MC. engines are done, the crank is pressed together, in peace's.
Honda does the same thing on their push mowers. But in that case the raw just slides over the crank. Same one piece design though
Just wondering, but after the engines are run through their testing cycle of about an hour, you said that the engines are drained of oil and cleaned up..... What happens to the oil they drain out? Do they filter and clean it? Dump it and use fresh new (expensive) or do they run a common tank that's pumped through the engine and back to the tank? Seems like a lot of oil being used, what happens?
S FERG
More like drops in a barrel. Don't sweat the small stuff.🦁✌
Their engines go for $20,000+. They probably just send the oil to a recycler.
Are you losing sleep over this ridiculous unknown?
I bet they don't use Windows XP anymore lol.
I bet money they still do. I have set up that exact torque monitoring software on dozens if not hundreds of machines. Rotax is just like the other motorcycle and auto companies. They run on ancient software because machines don't face the internet. It doesn't matter.
No, in America we do not think of Rotax as a aviation or sport engine....here in America we call them JUNK! I work at a BRP Can Am dealership. Motors are paper weights.
no gaskets...those engines must be oil leakers...the sealant breaks down over time..
Most nowadays engines are no longer mounted with gaskets ^^
HalfLifeAMD They don’t leak a drop!
Yes, they don't leak. Mostly o-ring sealing....
Gaskets are an invention to fix poorly made products. You should think before typing stupid things.
Rotax 912. Biggest piece of shit I've ever flown. Annoying to check the oil having to rotate the prop. Engine head would overheat on a modest cruise climb on 90F+ summer days leading to several cracked heads. It's a nice engine for a toy I suppose. Not a plane.
What was it mounted in? my friends kitfox has a 912 with over 2300 hrs without even a hiccup, poor cowling design making for poor cooling? doesnt sound right to me..
So true! You had a cracked head? Yikes! I’ve had more problems than I can count with my 912.
Can’t find hardly anyone to work on them. Rotech Canada has a disgusting approach to customer service. Overheating, leaking carbs, fuel pump failing after 5 hrs!!!!!! $800 radiators? Ughhhhhaaaa! 1000% regret owning anything with a rotax in it.
If you are thinking it won’t happen to you, think again. Just a matter of time until it screws you
Rotax has powered Ski-Doo snowmobiles since the late 1960s. Statements like “We tend to think of Rotax as an aviation engine company” demonstrates how out of touch many so-called experts really are.
Actually, Rotax engines were found in Bombardier's Ski-Doos as early as 1961 (I still have my father's 1961 Ski-Doo which has a Rotax). Bombardier (now BRP)
bought Rotax around 1962.
This is an aviation channel numbnutz. VWEB doesn't cover snowmobiles and Jet Skis. So to those that are into aviation and are here because of that, the statement is VERY TRUE. Go play checkers someplace else.
Yeah all 4 of my engines have failed. ... no more junktax for me. FYI. My latest engine for the last 2 years with no issues versus 2 months with these fucks that have almost killed me . Here's what's funny I build 1000 -1500hp engine's that get beat to death over and over weekend after weekend 10 times bigger for the same price so I pay some wing nut to build my plane engines that can't perform past just staying running. Sad!
You build engines? you actually cast all the casings and make all the internals? Lmao....fuck off idiot......modifying an engine is NOT building an engine!
poor workers no chairs to sit at their station give them reclining cumfy chairs that slide on tracks down the line if need be come on rotax
