The 912ULS is a well proven engine at a low price. Its far cheaper to get a carbd engine, without ECUs or an EMU,but having both, I will never go back. [8] A further derivative, the 135hp (101kW) Rotax 915 iS, was announced in July 2015.[9]. 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. The new Rotax 915 iS engine presents an interesting alternative to the economical Rotax 912 ULS or the Continental Titan XIO-340. 2 cents worth from an owner, Id say buy the 912iS or wait until the 915 is available, avoid the old tech dual carbd engines regardless of cost. Our price is lower than the manufacturer's "minimum advertised price." Please update your cookie preferences to see this video. The iS has more components, including the fuel injection system, ECUs and dual, high-pressure fuel pumps. In addition, Mitter collected broader data that showed that the 912 iS is slightly more efficient in climb than is the ULS. After a 4-month break, we are back at it. Learn how your comment data is processed. Soon after advancing the throttle, I noticed greater acceleration but two other parameters were more obvious.

A back-of-the-envelope calculation reveals that these numbers rival diesel efficiency and if mogas is factored into the equation, flying a 912 iS-equipped aircraft is substantially less expensive than the equivalent 912 ULS. Its numbers rival diesel performance. Facts: 4-cylinder 4-stroke liquid/air-cooled engine with opposed cylinders which has a control box. industrial art! *** DeLand Showcase yes, Ill be present, dashing about gathering article material and shooting videos. Ive been flying a P2008 with the 912iS for over 3 1/2 years out of CA, in the mountains. Earlier this year, Rotax. The 912iS has 2 stators one dedicated to engine operation and one to provide electrical power for the airplane. Glad it was a VFR flight in good weather. The last 914s we delivered had carb leaks at high manifold pressure settings. You cannot paste images directly. . I like the technical details. Dan, thank you. Such an aircraft is far outside our area of reporting. Use single quotes (') for phrases. The climb angle seemed vigorously steep, although this was my first experience in an Aquila aircraftso I had no basis of comparison. With the 914 my CT would be 150+ kts top speed. Hi Tyler: Thanks for your kind remark. Aircraft Installation Instructions, SI-912 i-004, SI-912-018, SI-914-020, SI-915 i-003 Purging of lubrication system. I am getting ready to build a Sling 2, 51% EAB, with Midwest Sky Sports. ROTALK NEWS Episode 5Rotax-powered Sling aircraft from The Aircraft Factory, the AVMAP Navigation and engine monitoring system, and the Rotax powered Tucano Experimental and Light-Sport Aircraft. This is beyond my experience base so will leave that debate to the forum. extend the cowling 3.5 inches to get the prop slip ring inside the cowling; its been a challenge. The ICON A5 uses the Rotax 912 iS engine, which is slightly different than the 912 ULS powerplant often found in other Light Sport aircraft. 80mm, P.C.D. Reconsider Cookies Side-by-side flight trials in an identical aircraft flown in a club operation show improved fuel economy of up to 36 percent, with at least 30 percent consistently achievable in routine block-to-block flight. Thank you so much. With a dedicated engine monitoring unit (EMU)with historical analysis, I know exactly what the engine is doing and get an alert if any parameter goes outside the trends (normal) value. Your email address will not be published. However, at the most basic level of Sport Pilot certificate, requiring only 20 hours of dual and solo, I dont believe a pilot should be reasonably expected to also learn about about in-flight prop adjustment; he or she may have no need or desire to acquire that skill. Price does not include shipping. An Astore with 912iS and a P2008 with the 914 :-). because I thought you saved a lot of carburator work, hence 912iS being simpler.. but I'm no expert. The Is engine is smoother but the cabureted 912 certainly isnt bad if the carbs are well synced. by drseti Sun Feb 26, 2017 9:30 pm, Post Aircraft ; Technical details . You do not have permissions to reply to this topic. Best speed for the 912i is at 7,500'DA Best speed for the 914 is prolly 16,000'. The Rotax 912 series is well regarded for its reliability and efficiency and is primarily targeted as . flyrotax 4.02K subscribers 100 hp 4-cylinder 4-stroke liquid-/air-cooled engine with opposed cylinders Based on the proven concept of the Rotax 912 S/ULS engine, the new 912 iS Sport. Takeoff roll is substantially reduced. It is more than most sport pilots may prefer and more than some should manage perhaps. 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. Copyright @2018 CTFlier.com In flying the 915iS I revisited the task of managing throttle and prop controls. 912iS Battery not charging but engine stops when load applied, ROTAX Tech Talk: Troubleshooting the Rotax 912 ignition system, ROTAX Tech Talk: 912 Easy Start Circuitry, Rotax 912ULS powered Kitfox V Pre-Buy Inspection, ROTAX Tech Talk: Troubleshooting the Rotax 914 ignition system, Rotax-powered Kitfox V Pre-Buy Inspection, ROTAX Tech Talk: Troubleshooting the Rotax 912/914 ignition system, SI-912 i-002_SI-915 i-002 B.U.D.S. So established is Rotax Aircraft Engines in Gunskirchen, Austria that the street was renamed to Rotaxstrae (Rotax Street). But more air is added in the combustion chamber He also explained that (perhaps surprisingly to some readers) the 915iS compression ratio is lower to allow for the turbo boost. By Gas vs. Diesel Rotaxs tests validate a trend thats been apparent in the automotive industry for two decades. To expand the data envelope, multiple aircraft were refitted with the 912 iS. The iS engine is very nice, but it's $3000 more than the ULS (current CPS pricing) and weights ~22lb more. [4] The 912 may be operated using leaded fuel, but this is not recommended as lead sludge tends to accumulate in the oil tank and reduction gearbox. Starting was as with any Rotax 9-series engine Ive ever flown. Using estimated performance data from the Tecnam P92 POH, we calculate a brake specific fuel consumption for the 912 ULS of about 0.44 pounds per horsepower/hour. Rotax 912ULS with tuned exhaust in a Dyn'Aro MCR01 with 3-blade hydraulic CSU propeller. Typically, ULS overhauls costs are about $13,500 to $15,000, but can be higher if valve or cylinder work is needed. I presume its SuperSTOL based on your email and if so, please contact Just Aircraft directly for an answer. We leave passenger aircraft to other magazines or websites. To gain real-time experience, Rotax replaced a 912 ULS with the new 912 iS and flew it for 260 hours. Id love to put this engine on an AeroTrek. The non-certified 912 iS targets the light sport and homebuilt aircraft market and 912 iSc will be certified. 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. At altitudes needed for California cruising there's a 20kt difference. It just depends on what you want. A fellow aviation journalist a pilot of 300 different aircraft Dave Unwin felt the 915 started softer. He also felt it seemed to run slightly smoother. The 912ULS has a single stator with 2 poles that are used for the ignition. Just make sure you know what you're getting into. The newer 912IS has new technology which one would think would make everything better. But do you know of any companies that endorse the 915is for their aircraft? No other modifications were done, according to Mitter, other than fuel plumbing. Michael is the key man behind the Aerotech/Rotax/Searey/MT Prop project to develop and refine a single lever control for light aircraft (see our video explaining this, or read our article). Stress is actually a little less therefore with the turbo engine, he said. Im about to take the plunge! The lightest engine in the Rotax aircraft engine portfolio. Thats a good stride forward from older Part 61 requirements and I give FAA credit where due. What make and model of turbocharger does Rotax use on the 914 and 915is engines? January 1, 2018 in Engine/Rotax. Just curious. The 912is is the latest in technology, full fadec w automatic lean of peak operation below 97% power. At this setting the 914 is making a lot more horsepower that a 912. Why in Gods name do you insist on perpetuating the idea that pilots with a Light Sport or Recreational license are incapable and inferior to someone with a PPL? you mean confidence because its well known? Climb was 1,000 fpm. Disadvantages? Facts . I believe that the iS line of engines is thefuture of aviation and that Rotax will give Lycoming and Continental a run for their money. Fuel needs of both 915iS and 912iS are essentially the same. I used to synch the carbs on motorcycles myself and found it easy. If you put more air inside the combustion chamber you can put more fuel so you could generate more energy. Required fields are marked *. For that question Im a firm advocate of the injected engine. I am torn between the 912ULS and 912iS. Which is your favorite (and why)? The 912is is the first full fadec aviation engine with auto lean of peak and it has been a challenge. I would prefer the 914 if I was you. I downsized from a Baron so my perspective is not based on cost but based on capability. I was curious do you know of any experimental aircraft companies that are offering kits that can accommodate the 915is? List ByDanJohnson.com all LSA Services each one verified to have the airplane or expertise you seek. 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. Many of the early installs didnt have this, mine didnt so we immediately added it and this is likely why we have had zero faults. If you have an account, sign in now to post with your account. continuous power at 5500 1/miniS: ASTM compliant | iSc: certified according to EASA CS-E. Plan on attending the Annual Sport Pilot Expo. I've been reluctant to recommend or invest in the 912 iS due to two things. You can have separate throttle and mixture controls.

ROTALK NEWS Episode 3Michael Smith's Rotax-Powered Searey Circumnavigation, the amazing Rotax-Powered Lockwood Aircam and Anthony Caere's chimpanzee rescue operations. We end up discussing pros and cons of the Rotax engines regularly. To receive critical-to-safety information on your ROTAX Engine, please subscribe toROTAX-OWNER.COM. Their state of development appears good now but prices need to come down and regulations need to be completed as presently forecast. Its quite a bit more costly and is more power than needed on Aerotrek. Overall both the Astore and P2008 are just physically largerthan otherLSAs so there is not a lot of difference. This decision can be reversed. Obviously, the cost savings for owners using mogas in the Rotax enginesand many dowill be less. What the refreshed experience told me is that FAA was right to say this is unnecessarily complex for recreational pilots. ROTALK NEWS Episode4ROTAX's 915iS-powered Aquila A211 test aircraft, the Scheibe SF-25C Falke (first-ever 912-equipped aircraft!) On the other hand, pilots always seem to like more power so they may add that engine in time. A key reason this is possible is because of liquid cooling versus my older experience in air-cooled legacy engines, for example, in a Cessna 182 Skylane. All rights reserved. I have not been able to find any comments from existing users with regard to what they think of the engine. I have a 912iS with 230 hrs. 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]. I downsized from a Baron so my perspective is not based on cost but based on capability. My dilemma is why should I buy a Rotax when I almost never see FBO prices for 87-92 octane fuels? In terms of power, our 912iSc sport engined P2008climbs out of Mammoth Lakes on a 90 degree day, with full tanks, two on board, one bag,at 1000fpm at 80KIAS. I recommendgetting a test flight in every aircraft you can! Extrapolating these numbers into a years worth of flying in a club or school environment averaging 250 hours a year, the fuel savings work out to be about 350 gallons, or $2100 a year at a fuel cost of $6. Id be a bit surprised if this conservative company embraced that. I would stick with the 912i. Based on the proven concept of the 100HP Rotax 912 S/ ULS engine the 912 iS SPORT engine offers all well known advantages of the Rotax 4-stroke engine series complemented by additional features, e.g. Shaft with flange for fixed pitch propeller P.C.D. Thanks. It's not terribly difficult or time consuming. 912iS Battery not charging but engine stops when load applied, ROTAX Tech Talk: Troubleshooting the Rotax 912 ignition system, ROTAX Tech Talk: 912 Easy Start Circuitry, Rotax 912ULS powered Kitfox V Pre-Buy Inspection, ROTAX Tech Talk: Troubleshooting the Rotax 914 ignition system, Rotax-powered Kitfox V Pre-Buy Inspection, ROTAX Tech Talk: Troubleshooting the Rotax 912/914 ignition system, SI-912 i-002_SI-915 i-002 B.U.D.S. The 912iS requires a more robust installation, as mentioned, things like metal fuel lines which require exact fits, unlike rubber hose, butit also requires the sensor tiedownkit, which is a few hundred dollar kit,with sensor specific tie downs to eliminate false alarms due to sensor vibration. Electronically-controlled fuel injection is the greatest difference between these two engines, and it is a considerable one. Our expectation is to have 400 engines out in the fieldby year end, Marc added. Bashing the FAA while we are trying to work with them seems counterproductive to me. Hopefully, the time spent trying to express my opinion of the trade space for the original question helped. There was a crash of a Diamond Twinstar. Mitter said the test protocol called for trials on days of similar temperatures and density altitudes and defined run periods. Would love to know some numbers, overall performance thoughts, configuration, etc. By comparison, the 912 iS appears to be running at about 0.36 to 0.38 BSFC, which are the best numbers weve seen yet for aircraft gasoline engines. 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. Glad you liked the article. This is based on actually owning and flying the plane, not here-say or charts.

I was replying to Jay who said he was doing a SS build with a 915 and was hoping to see what he mentioned in his post. [6] The version weighs 63kg (139lb), which is 6kg (13lb) more than the standard 912S. However, the engine received US Federal Aviation Administration (FAA) certification in 1995, and by 1999, the TBO had increased to 1,200hours;[3] on 14 December 2009, the TBO was raised from 1,200hours to 1,500hours, or 1,500hours to 2,000hours, depending on serial number. The Stock Box proved most helpful in observing many factors about the new engine. Great article! A benefit to fuel injected would be no carb heat control to fuss with, but on a 912ULS plane without a carb heat control, it's moot. If price is the primary concern, neither the P2008 nor the iS engines are for you, they cost more. The electronic fuel injected Rotax 912iS is a recent development. by jetcat3 Sun Feb 26, 2017 2:01 pm, Post 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. Display as a link instead, This decision can be reversed. Depending on the core credit assigned to the engine at TBO, that could pay for the overhaul and then some. Just SuperSTOL coming along ok working out 915 problems. It is true that the 115 hp is available for five mins. Sign up Top Rotax-Owner.com So perhaps the right answer is to add 2 more planes to my stable? Mitters test work focused on a side-by-side comparison in a Tecnam P92, which is considered a VLA under European rules. This seems to have left us with a choice of either a Rotax 912 ULS or Rotax 912 iS. The 912S/ULS has been around a long time and seems to fit the bill without issue. Perfected 4-stroke engine with full take-off power and engine management system. When you get up a bit higher your 100 hp non turbo will be making probably about 60 hp but the turbo is still making sea level hp up to about 16000, after that it drops off a little. But more likely, it will account for just a substantial fraction of the overhaul cost. Was easily resolved by a good Tech but goes to show nothing is ever perfect. Naturally, he is also intimate with the 915iS. Flying Sting S4 ( N184WA ) out of Illinois. Greaser! 75mm, P.C.D. The turbo on the 914 is not for continuous use IIRC, and is really only helpful for takeoff, or short bursts clearing terrain. On top of that directed to try another runway (first time at this location). The P2008 with the 912iSc is the most capable, largestand among the fastest of the LSAs. Similarly, in cruise, the iS did better at low altitudes than Rotax originally calculated, but at higher altitudes8000 feet and aboveit did much better, showing as much as a 36 percent improvement over the ULS fuel burns. Change Cookie Consent 80mm, P.C.D. Stress is actually a little less therefore with the turbo engine, he said. Nothing like a 40% boost in power to launch an aircraft into the sky. I have two Aircraft one with a ULS (100 hr) one with an IS 420 hr. by 3Dreaming Sun Feb 26, 2017 10:35 pm, Post Maybe the 915iS will bean option at some point unless its too heavy. We live in the KMNE/KDTO area and seek advice. Production started in March 2012 and the engine has a 2000-hour recommended time-between-overhaul to start. When zipping along faster than 170 miles an hour true, consumption rose to the 7-9 gph range. Hi Drew: Thanks for your kind words. Customer Service Information Report (CSIR). New FI.R.M. I know there have been issues with the 912iS, but is it all done with? The manual adds that non-compliance with such warnings could lead to serious injury or death.[10]. 912 UL / A / F 80 HP. Once at altitude, Christian demonstrated use of the throttle and prop controls this was not a single lever control airplane to adjust for speed or economy. We dont yet know if these will be required replacement items. Best of both worlds, fuel injected and turbo! On 8 March 2012 the company displayed its 912 iS variant, a 100hp (75kW) version with fuel injection and an electronic engine management unit. We already do it for Light Sport and to Light Sport Sea. kicktireslightfires, Jun 16, 2020 #1 Ghery Touchdown! In comparison to the 80 HP version of the Rotax 912 series the 100 HP product line offers more power while keeping the weight.

Carburetors are old technology, not well suited to different altitudes, step up to the 1980's and get a fuel-injected engine. Paul Bertorelli is Aviation Consumers Editor at Large. The 912S is certified, as are the A and F, which are used in the Diamond DA20, which is quite popular in Europe. Yet for those who yearn for more power or are building an aircraft of higher capabilities, the 915iS is going to be a welcome powerplant. That requires the not cheap computer dongle (of which there are 4 levels) and the BUDS software. You just described an excellent way to make a 20 minute procedure into an all day project. This is a surprisingly common accident factor in floatplanes in particular for whatever reason. In my opinion, this is not a simple decision. All three Rotax engines are offered by Tecnam because we believe they are all good viable choices. Regardless all the electrical power to run the engine comes from the engine. Rotax's 915iS uses the same displacement as the 912iS. We expect the 912 iS overhaul costs to be higher than the ULS, but we dont yet know how much higher. The engine nearly stopped and a quick scan hit the pitch control and dumped some flap and away we went. When I hear negativity about the 914 it is nearly always from someone who has never flown behind one. Paste as plain text instead, And I have two customers who now have the 912 iS (neither have needed work on their engine yet). We also are interested in engine overhaul specialty center with state of art facility available for immediate. This decision can be reversed. Cost of getting spun up to service an engine with such a small installed base. I live at 5,000 feet altitude, so a turbocharger is a must. * leaded, unleaded, AVGAS 100LL, Ethanol 10** max. Low-weight engine with excellent performance at high altitudes. Please contact Just Aircraft. Perfected 4-stroke engine with full take-off power and engine management system. Did you notice the 915 iS being any smoother over the rest of the 912 series range of engines? On introduction, the TBO was only 600 hours, which was double that of previous Rotax engines but far short of existing engines of comparable size and power. * leaded, unleaded, AVGAS 100LL, Ethanol 10** max. Engine with the best-in-class power-to-weight ratio. 912 UL / A / F. The highly reliable and efficient entry-level motor for light aviation aircraft manufacturers. 2. 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). Also as has been mentioned the 914 is quieter and very smooth. Definitely much better than when it was first released though. A new Airmaster propeller has arrived; it is a beautiful piece of I agree with Mark, the 912 iS was a bit smoother in my experience over the 912 ULS. Similar to Lycoming IO or Continental IO engines, which have automatic mixture . By using our website, you agree that we can place these types of cookies on your device. To get below 3 gph, a surprisingly low consumption rate, speed dropped below100 knots true or 85 indicated. The Astore is not hard to get in and out of but just not as easy as the 2008. While not especially hard you can hardly get in trouble with such equipment on a modern, liquid-cooled Rotax you nonetheless have to fiddle with levers and knobs, and keep an eye on instruments. I will cover many aircraft stories, but allow me to take the most recent first: flying the brand-new Rotax 915iS and comparing it to the 912iS, although not in the same airframe. According to the Rotax test data, the 912 ULS burned an average of 4.65 GPH in the test profile, while the 912 ULS burned 3.25 GPH for the equivalent power output, an efficiency improvement of 30.1 percent.
