Where can I find a Sling 4 for sale?

Every Sling 4 PlaneFox can see is on this page — 21 of them, gathered from the broker and dealer sites it re-reads continuously. Most are listed in Germany (3), followed by Hungary (1), Belgium (1), Switzerland (1) and France (1). Each listing links straight through to the seller, so a Sling 4 in another country is worth considering rather than filtering out.

What should I check when buying a used Sling 4?

On a used Sling 4, check airframe hours, engine time since overhaul, avionics generation and damage history before anything else. PlaneFox recommends a pre-purchase inspection by an EASA Part-145 shop that knows the type, which typically costs EUR 1,500 to EUR 3,500. Under 1,500 airframe hours is low-time and above 3,500 means budgeting for higher maintenance; most piston engines run a 2,000-hour TBO, so past 1,500 to 1,700 hours since overhaul expect the overhaul within one to three years at EUR 25,000 to EUR 45,000. Read the full logbook history for prop strikes, gear-up landings and structural repair, and confirm ADs and SBs are complied with.

About the Sling Aircraft Sling 4

Aircraft overview

The Sling Aircraft Sling 4 is a four seat, low wing, all metal light aircraft developed in South Africa by The Airplane Factory, now Sling Aircraft. The prototype first flew in 2009, with customer kit and factory assisted production following in the early 2010s. It sits in the experimental and kit built touring category, rather than the certified four seat market. The type matters because it brought true four place utility to the Sling family while retaining the efficient Rotax powered operating model associated with the smaller Sling 2.

Performance & specifications

Typical Sling 4 performance depends on engine choice, propeller, build standard and operating weight. With the Rotax 914 UL turbocharged engine, a commonly cited installation, cruise speeds are typically around 115 to 120 knots. Published range is often quoted at roughly 800 nautical miles with standard fuel and appropriate reserves. Maximum takeoff weight is commonly listed at about 2,028 lb, with useful load around 1,000 lb depending on equipment. Service ceiling is typically quoted near 15,000 feet. Later aircraft and upgrades may use Rotax 915 iS power, improving climb and high altitude performance.

Cabin & avionics

The Sling Aircraft Sling 4 has two front seats, a rear bench for two, and side by side controls. Cabin access is through a large canopy arrangement, and baggage capacity is suitable for light touring when payload is managed carefully. As an experimental aircraft, avionics vary widely by builder and year. Common installations include MGL glass panels, Dynon SkyView, Garmin G3X Touch, radio and transponder packages, autopilot, ADS-B equipment and engine monitoring. It is not typically associated with Garmin Perspective or a standard factory G1000 suite.

Buying & value

For used buyers, the key distinction is build quality. Review the builder history, logbooks, weight and balance, engine installation, cooling, fuel system, canopy fit, corrosion protection and service bulletin compliance. Confirm whether the aircraft is an early Rotax 914 example, a later Rotax 915 iS aircraft, or a project with incomplete documentation. Avionics upgrades can materially affect value, but workmanship and airworthiness records matter more. Current PlaneFox listing data shows an average asking price around EUR 50,000, with a broad spread from about EUR 6,000 to EUR 299,000, reflecting projects, kits, completed aircraft and highly equipped examples.
