Sling High Wing

Overview

The Sling High Wing is the newest member of the Sling Aircraft family, introduced as a deliberate departure from the low-wing configuration that defines every other Sling model. The origin story is unusually direct: founder Mike Blythe received a request from a customer who said he would buy a high-wing Sling if one existed, specifically citing ease of entry and exit. Development ran from 2019 to 2020, with the prototype’s first flight in December of that year.

The airframe shares its cantilever wing with the Sling TSi, grafted to a new wider fuselage optimised for four-seat comfort and straight-in door access. Construction is predominantly riveted 6061-T6 aluminium with fibreglass composites at fairings, cowling, and wheel pants, and a carbon fibre centre fuselage section. Current production aircraft are powered by the Rotax 916 iS producing 160 HP at sea level, turbonormalised to maintain rated power above 15,000 ft. Earlier builds used the 915 iS at 141 HP, and kits are available for either engine. An MT or Airmaster constant-speed propeller is standard. A ballistic parachute recovery system is included as standard equipment.

The aircraft is available in tricycle and taildragger variants, and is sold as an Experimental Amateur-Built kit. Builder-assisted and quickbuild options are available through Sling’s distributor network in the US, reducing build time substantially from the full-kit baseline.

Key Features for GA Buyers

High-Wing Visibility and Utility. The classic high-wing layout delivers excellent ground visibility for backcountry and short-field operations, and makes loading and unloading substantially easier than any low-wing alternative. The wide, straight-in cabin doors and a 46-inch cabin width make the interior genuinely accessible for larger pilots or passengers.

Turbonormalised Performance at Altitude. The Rotax 916 iS maintains rated power to above 15,000 ft, a genuine operational advantage over normally aspirated competitors like the Cessna 172. Above 8,000 ft the Sling’s power advantage relative to the 172 is meaningful: pilots consistently see 135–145 KTAS at altitude cruise settings, more than most 172 variants at equivalent altitude.

Modern Avionics and Safety Systems. The standard Garmin G3X Touch suite provides full glass-panel capability in an E-AB airframe at a fraction of certified-aircraft avionics cost. The ballistic parachute recovery system is standard, a safety feature unavailable on comparable certified aircraft.

Backcountry and Taildragger Variant. The available taildragger configuration, combined with the high-wing layout’s ground clearance and visibility, makes the High Wing a credible backcountry touring aircraft in a way that most kit four-seaters are not.

Trade-offs

• Experimental Category. As an E-AB aircraft, the High Wing requires a significant builder investment: full-kit builds run 900–1,400 hours; builder-assisted programmes reduce this substantially but add cost. Pre-owned examples exist but the type is recent enough that the used market is thin.
• Fixed Gear. The fixed tricycle undercarriage simplifies maintenance and insurance, but limits cruise speed relative to retractable-gear certified competitors. At 145 KTAS the gap is modest for most missions.
• Rotax Engine Ecosystem. The 916 iS runs on MOGAS or avgas and has a 2,000-hour TBO with 1,200-hour major service intervals. Rotax-trained mechanics are widely available but not universal; buyers in regions with sparse Rotax support should verify service access.
• No ICAO Standalone Designator. The High Wing has no independent ICAO type code; it shares the SLG4 family designator with the Sling 4 line. This has minor practical implications for flight planning and ATC communications.
