Was easily resolved by a good Tech but goes to show nothing is ever perfect. I would prefer the 914 if I was you. Also, avgas is incompatible with the recommended synthetic oil which cannot hold lead in suspension; consequently, the use of leaded fuel mandates additional maintenance.[3]. The electronic fuel injected Rotax 912iS is a recent development. [3] On the 912A, F and UL the standard reduction ratio is 2.27:1 with 2.43:1 optional. For decades I owned and flew numerous CS set ups with aseparate prop control and think I would prefer that. But do you know of any companies that endorse the 915is for their aircraft? (Both will remain available for now.) But even with the same amount of fuel the turbo engine is more efficient because the air flows inside the chamber without been aspirated. It's not terribly difficult or time consuming. We are going to have to Plugging that number into Rotaxs data reveals a to-TBO cost savings of about $13,000not quite the total overhaul nut, but no trivial sum, either. That's a $12,700 price premium or about 9 percent. I am torn between the 912ULS and 912iS. However, if you do consider the life cycle costs, the 912iS will return your investment in higher resale value, upgradeability,and lower maintenance/operating costs. In addition, Mitter collected broader data that showed that the 912 iS is slightly more efficient in climb than is the ULS. The complete package presents the latest technology in the aircraft engine industry and will enhance the flying and ownership experience of pilots. Ive been loving your reports! When single lever constant speed (CS)props become available, hopefully late this year, only the iS engines will be eligible sincetheyarefull fadec engines,that means only the 912iSor 915iS.

Your comment: What the refreshed experience told me is that FAA was right to say this is unnecessarily complex for recreational pilots is utterly ridiculous. The last 914s we delivered had carb leaks at high manifold pressure settings. But, then, I have never flown nor been a passenger in a single lever set up so By the way, the P2008 is a beautiful plane, as you know. Hi John: You are most welcome. Reconsider Cookies In power mode, it runs at about Lambda 0.8 or 0.9. When I hear negativity about the 914 it is nearly always from someone who has never flown behind one. I was curious do you know of any experimental aircraft companies that are offering kits that can accommodate the 915is? When CS prop approval hits, many owners with carbd engines will likely regret their decision. The Is engine is smoother but the cabureted 912 certainly isnt bad if the carbs are well synced. industrial art! The single lever requirement is what caused the altitude compensated carbs to be implemented versus amixture control so it is likely the FAA will remain steadfast on this requirement. Just SuperSTOL coming along ok working out 915 problems. *** I didnt notice the 915iS was more smooth than the 912iS I flew later that day, but it was certainly a smooth-running engine. As a result, we cannot show you the price in catalog or the product page. Joined: Feb 25, 2005 Messages: 10,820 Location: The Rotax 912 series engine powers dozens of types of light sport aircraft, and is widely considered one of the most reliable reciprocating engines available today. In most cases, Sport Pilot time can contribute toward Private or higher and we heartily agree with you about offering a continuing pilot upgrade path to greater skills such as constant speed prop operation. Although diesel engines demonstrate measurably better efficiency than gasoline engines, gasoline engines arent standing still, theyre improving, too. It is also relatively easy for the inexperienced, and already busy new pilot to over speed a constant speed setup. It was still powerful. The engine differs from previous generation aircraft engines (such as the Lycoming O-235) in that it has air-cooled cylinders with liquid-cooled heads[4] and uses a 2.43:1 PSRU reduction gearbox to reduce the engine's relatively high 5,800rpm shaft speed to a more conventional 2,400rpm for the propeller. In a four-cylinder, high-RPM geared engine, that sounded like an overpromise. Without providing much detail, Rotax said the 912 iS is also capable Lambda 1.3 or lean-of-peak operation. Which is your favorite (and why)?

The 912iS has 2 stators one dedicated to engine operation and one to provide electrical power for the airplane. Pasted as rich text. The addition of a controllable pitch propeller may require a single lever control, at present a single lever control is not required. Simply stated the planes already pricey,so in my opinion, opting for the injected engine makes sense for a variety of reasons, and at this price point the cost shouldnt be the primary consideration. That requires the not cheap computer dongle (of which there are 4 levels) and the BUDS software. Hence the push for single lever control, a simpler way to handle in-flight prop control. [Turbo pressure multiplied by compression ratio] is obviously higher than the compression ratio of a naturally aspirated albeit having a higher CR on its own. Its expensive but in this case you get what you pay for and given the comfort, performance and reliability, its well worth it for us. It is also fitted to some light twins, such as the Tecnam P2006T. Required fields are marked *. It features liquid-cooled cylinder heads and air-cooled cylinders. Belvoir Media Group, LLC. I believe it had been started but had a very weak battery. Must be due to the turbocharger and lower compression ratio. The 912 iS is approved for 91 AKI mogas, but in equipping the engine with future knock-sensing capability, Rotax seems to be anticipating approvals for lower-octane fuels. ROTALK NEWS Episode 3Michael Smith's Rotax-Powered Searey Circumnavigation, the amazing Rotax-Powered Lockwood Aircam and Anthony Caere's chimpanzee rescue operations. I believe this is because of the slightly lower compression ratio but I could be wrong on that. For both engines, the aircraft was climbed to a specific altitude, leveled and allowed to stabilize on one fuel tank. Im about to take the plunge! And I have two customers who now have the 912 iS (neither have needed work on their engine yet). You can have separate throttle and mixture controls. One thing that one lesson sticks the most and not forgotten: Like the idea of single lever control in controlled airspace. 75mm, P.C.D. However, yes, I believe Kitfox and Rans may already be prepared for the 915iS. but 100 hp continuous. Thank you so much. I have also reported that the agency made errors previously, such as demanding reciprocating engines (thereby inadvertently eliminating electric), and we are working to find remedies. - All Rights Reserved. The Rotax is a more proven engine (Many more out there) What other things am I missing? [3] The original 80hp (60kW) 912 UL engine has a capacity of 1,211cc (73.9cuin) and a compression ratio of 9.1:1. 100mm, Shaft with flange for fixed pitch propeller, P.C.D. Earlier this year, Rotax. In terms of the CS prop, as I understand it, there is only one solution for US-LSAs being evaluated,and that is for a single lever control, and only the iS engines are able to interface with this system. It just depends on what you want. 75mm, P.C.D. [3], The 912 is more fuel efficient and lighter than comparable older engines, e.g., Continental O-200, but originally had a shorter time between overhaul (TBO). This requires a novel preflight inspection procedure: before checking the oil level with the dipstick, the engine is "burped" by removing the oil filler cap and turning the propeller until a gurgling sound is heard, which indicates that all oil has been forced into the tank and the oil level can now be checked accurately. Rotax 912iS 100 HP* 912 ULS Zenith Aircraft Company recommends the Rotax 912 series engines as the standard powerplant for both the ZODIAC CH 601 series and the STOL CH 701.

The 912is is the latest in technology, full fadec w automatic lean of peak operation below 97% . Even as the 912 iS was being announced last year, Rotax was already flying comparison trials, but the initial fuel economy data it released was based on dyno runs and some flight testing. It can do what the 912 can't and you could really use it because you are surrounded by mountains. Motor as the sport upgrade already done. We expect the 912 iS overhaul costs to be higher than the ULS, but we dont yet know how much higher. That being said, my next personal aircraft WILL have a 912 iS engine and I will buy the BUDS Level 2 service kit. I had some issues with gearbox, however all corrective work was in warranty. Yes, only Aerotrek can advise about the 915 availability. The 912 iS ECU is programmed to run in eco mode at 77 percent power or less, at which point the engine will operate at what European engineers know as Lambda 1, or a stoichiometric air-to-fuel ratio of 14 to 1. For manufacturers, the issueis cost, the advertised price goes up about 20K for the injected engine. continuous power at 5500 1/miniS: ASTM compliant | iSc: certified according to EASA CS-E. The injected engines have/require among other things metal fuel lines, high pressure filters, and providesubstantially more electrical power along with over 27 engine sensors and dual redundant Engine Control Units (ECU). Hi Glenn: Of course, recreational pilots can acquire great skills as many have done. The 912ULS has a single stator with 2 poles that are used for the ignition. With the 912i my CT would be 127+ kts top speed. Paul Bertorelli is Aviation Consumers Editor at Large. The gearbox has proven to be generally trouble-free.
