About the Sling TSi

Overview

The Sling TSi is a four-seat, low-wing Experimental Amateur-Built kit aircraft from South Africa’s Sling Aircraft, powered by a turbocharged Rotax 915 iS or 916 iS and cruising about 155 knots true on roughly 7 to 8 gallons an hour. Introduced in 2018 as the successor to the piston-powered Sling 4, it pairs a riveted-aluminium airframe with a full Garmin G3X Touch glass panel, and has become one of the most popular four-seat homebuilts of its generation.

Within the Sling line the TSi is the fast low-wing tourer, sitting above the two-seat Sling 2 and sharing its cantilever wing with the Sling High Wing. Buyers cross-shop it against certified composite singles like the Cirrus SR20 and Diamond DA40, which it undercuts dramatically on acquisition and operating cost while trading away type-certificated status and a factory-built airframe. Its turbocharged engine holds rated power into the mid-teens, so it earns its keep on long cross-country legs where higher, cooler, windward altitudes pay off. It suits the buyer after modern glass-panel four-seat cross-country capability on a homebuilder’s budget, for whom the Experimental category and the build commitment are acceptable trades for the savings.

Key Features for GA Buyers

  • Turbocharged altitude performance. The Rotax 915 iS or 916 iS holds rated power to roughly 15,000 ft, letting the TSi cruise high to find better winds and cooler air while burning only about 7 to 8 gph of mogas or avgas.
  • Full glass avionics. Most TSi builds carry the Garmin G3X Touch suite with integrated engine monitoring and autopilot, putting IFR-capable panels in the airframe at a fraction of certified-aircraft avionics cost.
  • Genuine four-seat payload. A useful load near 950 lb on a 2,094 lb gross weight makes it a practical family aircraft rather than a two-adults-and-baggage compromise.
  • Low operating cost. Mogas capability and a simple fixed-gear airframe hold direct operating cost near $60 an hour, well below comparable certified four-seat singles.

Trade-offs

  • Experimental category. As an E-AB aircraft the TSi must be built (roughly 900 to 1,400 hours) or bought pre-completed, with maintenance, insurance, and resale dynamics different from certified types.
  • Fixed gear. The fixed undercarriage simplifies maintenance and lowers insurance but caps top-end speed against retractable high-performance singles.
  • Rotax ecosystem. The 915 and 916 iS run on mogas or avgas with a 2,000-hour TBO, but add calendar-driven service such as the 5-year rubber-and-hose replacement, and need Rotax-literate maintenance, which is widespread but not universal.
  • Thin used market. A recent design built in limited numbers means pre-owned examples are scarce and pricing is builder-dependent, so condition and build quality vary widely.
