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.
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.
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.
In a 2016 detailed review for Flying magazine, writer Marc C. Lee praised the design's controls, handling, aesthetics and load carrying capabilities, while pointing out that it lacks cruise speed, an effective heater, has poor rubber molding and lacks a USB jack system. He also noted it cannot be taxied with the gull doors half open or cracked open.
