Flew 20 years with traditional engines, bought a Flight Design CT with 912 last year - Rotax engine is so impressive. Zero oil leakage / burn, amazing performance & fuel economy, starts and runs smooth as silk, instant throttle response - these engines in LSA aircraft are an amazing combination. ~ 130 hours flying behind it, will be 9 series owner for as long as I'm flying.

Just curious how long ago this video was shot. I have a 912ULS and my IA told me that the recommended oil change was lowered from 100 to 50 hours for unleaded fuel and from 50 to 25 hours for 100LL fuel. Never hurts to change oil early. Just curious if I misunderstood somewhere along the line

@ExperimentalAircraftChannel 3 года назад

Just a few months ago.

@randyvanvliet226 3 года назад

I'll take 95 to 97 HP in a tightly cowled Van's RV-12 any time, if I don't have to worry about carb heat and icing problems with the carbs, every time. Did a lot of research on history and longevity of the Rotax 912 ULS, and as far as I am concerned, it's a winner. Keep fresh synthetic Mobil 1 T40 motorcycle oil and filter in them, keep your spark plug gaps at 0.022" to 0.025", synch those carbs, keep an eye on float weights, and balance that prop, and you should have a lot of longevity. My motor just doesn't use much oil, I run 91 octane Mogas almost exclusively. Stay away from the 100LL AVgas, if you can.

@andrewmorris3479 3 года назад

The 912/914 carb engines are indeed hard to beat. After logging over 1,000 hours behind them in a year and a half I’ve become a huge fan of Rotax engines and believe they are hands down the best piston engines in GA.

@jamesgrieve188 Год назад

Had an engine loss of RPM on take off. RPM dropped from 2200 to 1200RPM. Any ideas on what happened. Carb icing wasn’t the issue.

@foesfly3047 3 года назад

Has amperage output of the integrated alternator increased on the 912iS, compared to the carbureted version? Is that why the stator has to be oil cooled now?

@ExperimentalAircraftChannel 3 года назад

That is what I am thinking. Or just and engineer having fun with being creative! :-D

@jetrep 3 года назад

He painted a rosy picture. It'd be nice to hear a bit more about the realities of ownership. There must be downsides to the injection... how does one troubleshoot problems? Can I plug in an automotive scan tool? I've read some airplane suppliers struggle with meeting the cooling requirements of these engines and the installation of the injected engines is quite a bit more complex compared to carb versions. They do seem like great engines.

@acengineer737 3 года назад

If I remember rightly you are able to download the required software from rotax. Or it might be supplied with the engine, it’s called BUDS. If the cowlings aren’t designed correctly then any engine will have cooling issues. I really like the rotax engine. Worked on and flown with Lycoming/conti for years. Both manufacturers make good dependable engines, but they are just out of date and use far to much fuel. Been impressed so far with rotax. Done the factory maintenance training, which anyone can do. And now have an aircraft with a 912 UL. For lots of good information go to www.rotax-owner.com/en/

@garyspencer-salt4336 3 года назад

@@ExperimentalAircraftChannel This was noted when removing an IS from a certified Foxbat and if you exceeded the total number of connects disconnects here will require a replacement loom. Foxbat will no longer install the IS as it is too much work and weight and they claim they are unable to recover the additional cost. The loom from memory weighs in excess of 3kg when removed. In an experimental, it would not be an issue as it's your call.

@barrywald8595 3 года назад

Hi, great video. Can someone please explain - at 9:30 of the video a graph is showing Kg CO2 per 100 hours flown. Take the 912is as an example. Assume 18l/hr burn of fuel. This equals approximately 13.5Kg of fuel. After 100 hour 1350 Kg of fuel would have been burnt. How does 1350Kg of fuel produce 4,000 Kg of CO2? I look forward to the tech experts answers. Barry

@yanickdessureault203 3 года назад

The reason is that the carbon C is burn and when it exit the engine it's combine with the oxygen O2. So we have to add the weight of the oxygen to the carbon weight.

@foesfly3047 3 года назад

Will the iS engines continue to run if the ship's battery(s) fail? 1) Would the integrated alternator maintain electric fuel pumps? A) Is there a mechanical fuel pump? 2) does the ignition system require external 12v power source (or is it completely independent) ?

@KenLeonard 3 года назад

The 914 needs battery power for the fuel pumps. That is why one is wired direct to battery and one is through alternator. Presume similar for the 915 and Is.

@jaydenritchie6351 3 года назад

Price and availability?

@foesfly3047 3 года назад

He said there is more maintenance required for the GEARBOX on the iS compared to the ULS-- I wish he would have explained. I can't imagine why an improved fuel delivery system would impact such gearbox differences.

@Waretwo76 3 года назад

The injected engine runs hotter than the carb version when in cruse due to a lean mix, which gets you great economy. The gearbox shares the engine oil and consequently it runs hotter as well. That shortens the service interval. Lockwood will install a oil spray for the gear set on overhaul which should carry away the extra heat.

@carlsonthomas 3 года назад

The Rotax maintenance manual talks about inspecting the gearbox earlier in the lifecycle if 100LL is used vs running mogas/no lead fuels.

@Waretwo76 3 года назад

The 100LL shortened overhaul hours apply to the entire series, both injected and carb versions.

@ExperimentalAircraftChannel 3 года назад

Interesting. Yes... Carbon = Dirt. So... change the oil. Makes sense. Same with lead I would assume.

@thewheelieguy 2 года назад

Yes, the reduction gear set is pressure lubricated for longevity and temperature control. It shares a feed from the oil pump, same as the engine.

@indyjones1970 3 года назад

Newby here. Can someone tell me the advantages / disadvantages of the reduction drive, and why direct drive is not possible with this engine? It seems to me to be an extra stress point for the engine, and more parts/weight.

@MrBtdobie 3 года назад

Reduction drives are necessary in engines that turn more than about 3000 RPM because propellers become very inefficient if you spin them faster than that. So then the question becomes why would you build a high RPM motor and add the weight/complexity of a gear box? The main reason is that a higher RPM motor creates power at lower torque so there is less stress on internal components so they can be built lighter. High RPM motors can also make more power at lower compression which makes Mogas a more viable fuel. This is far from comprehensive and doesn't hit on the advantages of high torque direct drive motors, but hopefully it gives you a starting point.

@indyjones1970 3 года назад

@@MrBtdobie Thankyou for taking the time. Makes sense finally.

@georgschroeder2123 2 года назад

@@MrBtdobie A Prop mustn't turn faster than transsonic speeds. Depending on it's Diameter the Prop-Circle-Speed has to be below the speed of sound. So mostly about 2200 to 2300 RPM. The Rotax turns about 5400 RPM, so you need a gearbox.

@gunnerjoe53 3 года назад

As a comparison what is average hours on a car engine when it would be good idea to rebuild?

@cautionjaketurbulence8891 3 года назад

Depending on the type of engine. If we assume an engine will need significant maintenance at 150,000mi, the average person would need a rebuild after about 3,750 hours of driving. It's hard to estimate the time the car spent at idle during those 150,000mi so 3,750hours is a low number. Of course some engines last longer and some don't last as long. Your question is a pretty broad question but remember if your car breaks on the side of the road, you're just stuck. If your airplane engine breaks, you could be facing death. Aircraft maintenance is held to a much higher standard than automotive maintenance.

@Cavalier-lp8tr 3 года назад

Isn't maintenance availability going to be an issue for some builders? It would be easier to find and A&P who can work on a conventional type engine versus something like this.

@KenLeonard 3 года назад

That is possible but you can either go to the engine school for rotax yourself or you can ask around your area. You might be surprised. There are 10s of thousands of these in US.

Turbo is something just as important also for coping with high altitudes and maintaining the power. So it takes them 100 years to get to this? I had can am 1000cc and I was so dissatisfied that I was close to smashing it and burning it and showing it on youtube. So this video probably says the most about what the backward brand rotax is. With that said, the 915IS and the next 916is are interesting and good engines, I guess.

As soon as I see Rotax name, I already know the airplane is unaffordable for many. Rotax have not done the industry much favor in terms of cost reduction. A big company with lots of overheads and share holders to pay for. It is also snail slow in tech advance, some engines still use carbs, and they are slow at raising HP. This gave an opening to companies like Edge Performance. A smaller and more agile company that can do what Rotax cannot.
