Powerplant and Propeller
Your Sling 2 is powered by a Rotax 912 / 914 and is available as a 912 ULS, 912 iS or 914 UL. A 100 hp Rotax 912 ULS offers a time between overhauls of 2,000 hrs and is the best power to weight ratio in its class. Alternatively, the Rotax 912 iS offers all the well-known advantages of the Rotax 4-stroke engine series as well as additional features which will ultimately enhance the flying and ownership experience of pilots. A 115 hp turbo charged Rotax 914 UL on the other hand, offers more performance at high altitudes while delivering lower weight engines. When powered by the Rotax 912 ULS / iS, the Sling 2 is fitted with a Warp Drive 3 Blade Ground Adjustable propeller. These propellers are more affordable and lighter in weight and when compared to a fixed pitch propeller. Ground-adjustable propellers mean that pitch changes can be made on the ground to optimise the aircraft for current payload and flying conditions. However, when powered by the Rotax 914 UL, your Sling 2 is fitted with an Airmaster 3 Blade Constant Speed propeller. Variable-pitch propellers automatically change its blade pitch in order to maintain a chosen rotational speed. As a result, this operation perfectly suits modern engines, particularly the turbo charged variety.
