Sling 4 Small


The Sling 4 concept emerged from the performance of the standard Airplane Factory Sling 2 during Mike and James' 2009 circumnavigation of the earth.

Conceived as a 600kg Maximum All Up Weight "light sport" aircraft, it was soon clear that, even with a normally aspirated 100hp motor, the standard Sling was able to climb and perform well right up to 970kg.

The first consequence is that The Airplane Factory Team performed all the required tests and approved the standard aircraft at 700kg MAUW. We also simultaneously commenced work on development of a light 4 seater version of the same aircraft.

The chief differences between the Sling 2 and the Sling 4 are the wing size, the engine and the centre fuselage arrangements. Where the standard Sling customarily uses a 100hp Rotax 912 ULS or iS engine, the Sling 4 ais fitted with the 115hp turbocharged Rotax 914 UL engine.
Although a 15hp difference doesn't sound like the world, the turbocharged engine gives full power at up to 15 000 feet, at which altitude the 100hp would only be delivering approximately 55hp. So, on a hot day the swing in power between the 912 ULS and 914 UL engine is in the vicinity of 36%, not just 15%.

The Sling was designed with the aim of creating the most practical and desirable light sport aircraft available.

Some of the characteristics which make the Sling range unique:
  • The Sling's flying characteristics make for a perfectly coordinated, highly responsive control setup. This gives her the distinct qualities of a fighter jet aircraft, while not being overly sensitive.

    The Sling's performance matches and outdoes almost every aircraft in its class, while being highly economical and fun to fly.

    Its aluminum construction makes for ease and consistency of construction, while offering proven strength and a longer lifespan than some of our composite rivals.

    The Sling's airframe strength and durability means that she won’t break easily and, if you treat her right, she’ll last you for the rest of your life

    Her excellent instrumentation options make for a very unique, state-of-the-art flying experience, at a fraction of the cost of our certified competitors.

    The wide cockpit, excellent all around view and substantial luggage capacity make the Sling a very comfortable, yet versatile aircraft.

    The incorporation, by design, of a ballistic parachute, makes the Sling an exceptionally safe aircraft to fly.


The Sling 4 is our new addition to the Sling light sports aircraft family, featuring 4-seats.
