What is the difference between 915 iS and 916iS?
The 915iS produces 141 horsepower at takeoff and costs around $43,700, with a 1,200-hour time between overhaul. The 916iS delivers 160 horsepower at takeoff and costs about $51,400, but it runs for 2,000 hours before needing overhaul. Compared to the 915is, the 916is achieves the same maximum continuous power with 10-20% lower fuel consumption. The initial time between overhaul is 2,000 hours.
What is the difference between Rotax 915 and 914?
Rotax 915 iS The 915 iS puts out roughly 22% more maximum power and about 32% more torque than the 914 UL. In a light aircraft, that difference is enormous. It translates directly into faster climb rates, higher cruise speeds, and better performance on hot days or at high-density altitude airports. At 141 hp max for five minutes, the Rotax 915 iS is the lightest, most powerful factory-provided aircraft engine. As far as powerplants go, the world of experimental aircraft lives in its own creative cloud.Rotax 915 iS The 915 iS puts out roughly 22% more maximum power and about 32% more torque than the 914 UL.

What does Rotax stand for?
Rotax is the brand name for a range of internal combustion engines developed and manufactured by the Austrian company BRP-Rotax GmbH & Co KG (until 2016 BRP-Powertrain GmbH & Co. KG), in turn owned by the Canadian Bombardier Recreational Products (BRP). Rotax engines are famous for their reliability and best-in-class power-to-weight ratio. Versatile, cost-efficient, and easy to use and maintain, Rotax engines have gained the trust of flight schools, home builders, and aircraft manufacturers alike.There’s a yin and yang to the numbers here, which is to say pluses and minuses. The 915 iS’s power-to-weight ratio is 0. HP/lb. S is 0. HP/lb. Looking at other engines in the Rotax line, the stalwart 912 ULS has a power-to-weight ratio of 0. HP/lb. Rotax dry weight data.Rans’ price for the 80 hp Rotax 912 UL is now $16,350, down from $17,495 in January. 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.
How often does a Rotax 912 need servicing?
Rotax reduce the oil change intervals to 50Hrs (if you can, 25hrs wont harm) replace the spark plugs every 100hrs & have the slipper clutch inspected every 600hrs. So using Avgas will see you having to do a bit more maintenance. USE OF AVGAS: If you find it necessary to use Avgas in your Rotax 912/914 aircraft engine you will need to replace your spark plugs twice as often, and change the oil and oil filter at least every 50 hours.
