  The Anglin J6 Karatoo is an Australian ultralight and light-sport aircraft that was designed by Jesse Anglin and introduced in 1982. Over the years the J6 Karatoo has been produced by several different manufacturers, including Amax Engineering of Donvale, Victoria, Skyway Aircraft and is currently built by Serenity Aviation of Australia. The aircraft is supplied as plans or as a kit for amateur construction.
  
  ## Design and development
  
  The aircraft features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit with doors, fixed conventional landing gear and a single engine in tractor configuration.
  
  The aircraft fuselage is made from welded 4130 steel tubing, with its wings usually made with a wooden structure, all covered in doped aircraft fabric. Its 32.5 ft (9.9 m) span wing employs a Clark Y airfoil, has an area of 146 sq ft (13.6 $m^2)$ and optional flaps. The wing is supported by V-struts and jury struts and is constructed with marine plywood ribs and a D-cell leading edge, although a metal wing was under development. Wing folding for ground transport or storage is optional. Floats for water operations are an option.
  
  The Karatoo can accept engines in the range of 50 to 100 hp (37 to 75 kW), depending on the model. Engines used include the 50 hp (37 kW) Rotax 503 and the 64 hp (48 kW) Rotax 582 two-strokes as well as the 80 hp (60 kW) Rotax 912UL, the 100 hp (75 kW) Rotax 912ULS, 85 hp (63 kW) Jabiru 2200, 71 to 100 hp (53 to 75 kW) Subaru EA engine, 90 hp (67 kW) Continental C-90 and the 100 hp (75 kW) Continental O-200A four-stroke powerplants.
  
  In 1988 the J6 design was adapted to the Canadian ultralight rules as the Norman Aviation J6 Karatoo and, in 1990, as the Buzzman L'il Buzzard.
  
  ## Operational history
  
  In August 2012 there were 14 J6 Karatoos registered in the United States with the Federal Aviation Administration in the Experimental - Amateur Built and light-sport categories.
