Design and development
The Sling 4 is an all-metal, low-wing, fixed tricycle gear homebuilt aircraft. The aircraft was developed in 2009. The canopy was modified to include gull-wing doors. The aircraft features flaps with 40 degrees of travel.[1][2]
Operational history
In July 2013 a Sling 4 was flown by Mike Blyth and his son from South Africa to AirVenture in Oshkosh, Wisconsin, United States. The flight included a 14-hour over-water leg. The aircraft carried 20 hours endurance in fuel.[3]
A Sling 4 kit was completed and flown in four days with 40 workers at a 2014 South African Airshow to demonstrate the effort needed to build an example of the aircraft.[4]
