Description

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.
