Unlike Lycoming and Continental, Rotax has a modern advanced efficient assembly plant that should create cost savings that Lyc/Cont can't match. However, the factory is located in Austria which is about the most expensive place in the world to manufacture anything. And the cost of freight, customs and a distributor such as Lockwood means that any cost savings evaporates. UL has the same problem but also has a small engine assembly shop like Lyc/Cont. Non aero engine conversions could gain more market penetration as the prices continue to increase. Also, increasing the LSA weight limit will also benefit the engine conversion segment. Also, Factory support in the USA for Rotax for the most part is terrible.

Lol you can get the same hp, 40lbs lighter for about 6k with a yamaha apex engine with an sds control system and a stinger redrive. And yes there are several of this set up already flying and have been for awhile now.
@Captndarty lol its been flying just fine for more than a year with no issues other than some teething issues early on. Rotax engines run just as high. On the project I follow closest cg also has never been an issue soooooo....
Rotax do not run just as high. I can get a faster airspeed at 5000 engine rpm than you can at 8000 engine rpm. Soooo there’s that….. many people like yourself buy multiple apex engines because in the back of they’re mind they don’t 100% trust a used engine out of a wrecked machine. I’m not saying there’s in the market for the Yamaha, but it’s an extremely small percent experimental aircraft. It doesn’t work for most people. And quite frankly, besides it’s obvious capabilities, for “stol” the people that get on the high horse about the Yamaha motor are quite often obstinate and cheap or both🤷🏻♂️
@@Captndarty The way you talk sounds like a person comparing a contisaurus engine to a rotax. As an engineer, the apex engines are far better, but would be better if designed for a cruise rpm of 6000. I am using a Suzuki M13A and it is far superior to Rotax. The issue is people using an engine in an aircraft designed for a different engine, it is not the engine itself that is no good.
@@Captndarty exactly that's how rotax started with few engines from a high rpm snowmobile engines, yamaha reliability is higher than rotax. Rotax regular engines are crap, oil and waterpumps gears are plastic. Wait for yamaha aircraft engines.
With respect to percentage of power. If you run either the 915 or 916 at 75% power is that percentage of the max continuous of 135, or its maximum of 140/160? For example is 75% power of the 916 greater than 75% of the 915? And if so would the 915 at 80% be equivalent to the 916 at 75% or thereabouts? I’m trying to find out if there’s any real benefit to the 916 over the 915 which I already have other than a 14% increase in takeoff power for five minutes.🤦🏻♂️
If they are running more boost and both keep the MCT RPM the same, then the 916 will give you the extra power. Tbh in the LSA market that this is aimed at 160hp seems a little overkill.
Idk, I'm kinda meh about this. The engine is a suped up 915 that can handle some extra power for a little bit of time. That's great for the stol crowd, but for everyone else this is just a more expensive 915.
It costs 15% more than the 915 for exactly 15% more horsepower and with the added bonus of a massive increase from 1200TBO to 2000TBO. That's a pretty good deal if you ask me.
We're talking about not knowing what!))) Don't ask unnecessary questions! You just need to add 10,000 dollars for customization and for the color of the covers!)))
Upgrade the internals, forge them or triple forge them, larger fuel injectors, change the ecu program, it's not a ridiculous horsepower increase they didn't try to double it. They also have the data on all the testing and real world running issues with essentially the same engine in the 915 at least, so they fix those issues as well. What's the weight difference. If there isn't a huge penalty for weight how would 200 hp hold up with this configuration? Sounds like maybe they are holding back on performance a little, in my view. The only limit I see is how much charge air can you fit into those 4 cylinders? Looks like you could rebuild your stock 915is and get 916is or greater performance with the information presented in this video.
Thanks for the info. Looks like a badass engine.. Wish he'd had mentioned the weight.. Pretty sure, I won't see the need in a powered parachute configuration,, but for you GA folk, wow.. Rotex 503 still a great choice, just harder to find parts..
A "TBO" for an "upgraded" experimental aircraft engine. You bet. Of course that's if its installed, maintained,.serviced and operated PRECISELY to manufacturer "recommendations". And is that "aero engine" a FIXED WING engine or a ROTARY WING engine?
I really like the Rotax product, doubling the rpm in order to reduce the displacement while making the horsepower with a modern ignition and fuel system, low weight makes sense. Unfortunately, it appears Rotax is going the direction of Lycoming/Continental and becoming a super expensive boutique aircraft engine manufacturer. But you can actually overhaul and rebuild a Lycoming/Cont and find them on the used market. A Rotax cannot be overhauled or rebuilt as the factory and Rotax distributors such as Lockwood highly discourage it due to cost and they would rather sell you a new one. They are throw away engines once they fail the condition inspection. My friend the A&P who works only on LSA says only 4 shops in the US are "allowed" to split a Rotax case. I just don't get it. The door is wide open for Yamaha or anyone else to step in with a high RPM engine from the factory. You would think these engines are made out of Gold or Silver.
Totally agreed *BUT* they really need to target the aircraft market. That's pretty much running at full power for extended periods. Yamaha makes boat engines and other high endurance high power continuous engines - so they have the know how somewhere in their company - not sure they see it as worth investing in air.
I know Lycoming and Continental (and Jabiru, ...) also can be improved a lot by several unofficial modifications and STCs while Rotax have a single unofficial modder as far as I know.
Rotech in Canada can rebuild them. They are VERY difficult to deal with. Its like they know they have a corner on the market and will use it against their customers... Not cool
The more you fly the less complex you need to be worried about same reason lyc and contys still air cooled using pushrods more than stood test off time
Rotax builds some really great engines and the new 916is is no exception. However, they're incredibly overpriced, so I'll be installing a Viking engine in my aircraft build. Yes, the power to weight ratio isn't quite as good, but with it being over $30k cheaper, parts costing much less and still having the legendary Honda reliability, I'll be quite happy with it.
I really would love to know what it costs Rotax to build, granted there is some R&D involved in price but jeeze, over 50k for a motor?? that will cost u another 20k after your 2000 hr TBO..... I know they are well built light weight motors but ive always had a dislike for a 5k RPM at cruise 4 stroke......
I thought viking had a ton of problems on their "reliable" honda - at least at the start it didn't really live up to the thinking. Do cars run max power all the time? That's a big diff from car vs airplanes. I'm sure they fixed some of the issues over time, but at least at the start my impression was some real issues with the "honda reliability".
@@randominternet5586 This is another reason to look for other engines to convert besides common car engines, they may be more expensive or trickier but the amount of effort to convert them may be smaller because they were made for higher continuous power output, rougher environments, ...
That is stupid amount of money for an engine. I love how the aviation community wants to make more pilots ……but…. Only if you are extremely wealthy. Between training and owning being so expensive it will be a slow death for the aviation community.
A 13% increase for 5 minutes and a 1.5% increase in max continuous is MASSIVE POWER!? What adjective is left when there really is a significant power increase such as 50%? 😂. Given that the new price is $7,000 more than I just paid for a 915iS, that is a pretty pricey few horsepower.
@@andrewmorris3479 How are they pulling a fast one? Have you seen Dino results on a 916 yet? It may well dyno above its published specs also. Even Lycoming and Continental engines routinely dyno above their published HP specs. It is common for engine makers to be conservative on what they publish.
@@LTVoyager Because there are 915’s already pushing 50” at 5800 which equals 160HP. I can assure you the 916 isn’t doing more than 160HP. How else can you convince the world the 916 iS is a “new” engine? 146HP at 45” doesn’t sound very different than 160HP at 50”, and it certainly doesn’t justify 9K more. I’m disappointed with how Rotax chose to proceed here.
50k ??!! 😂 Rotax gained popularity in the aircraft world for being an alternative to the high dollar continentals and lycoming. 50k for 150hp that's just ridiculous. Good thing though, is companies like jabaru can afford to aggressively fill in the market where rotax used to be the obvious choice.
That’s the beauty of fadec
Engine last longer and in the end can produce more power
