The Sling is manufactured by 'The Airplane Factory' in South Africa. The design was by owner Mike Blythe who has many years of experience in aviation.
The two current models are the Sling 2 (2 place) and Sling 4 (4 place). It is available with either tail dragger or tricycle landing gear configuration. Construction is principally aluminium and is offere and is offered as a easy to assembly kit.
Airmaster have supplied many propellers for the Sling, improving the performance and usability of the aircraft.
