==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]].<ref name="serenityaviation2"/>

The aircraft [[fuselage]] is made from welded [[4130 steel]] tubing, with its wings usually made with a wooden structure, all covered in [[Aircraft dope|doped]] [[aircraft fabric]]. Its {{convert|32.5|ft|m|1|abbr=on}} span wing employs a [[Clark Y]] [[airfoil]], has an area of {{convert|146|sqft|m2|abbr=on}} and optional [[Flap (aircraft)|flaps]]. The wing is supported by V-struts and [[jury struts]] and is constructed with marine plywood [[Rib (aircraft)|ribs]] and a D-cell [[leading edge]], although a metal wing was under development. Wing folding for ground transport or storage is optional. [[Floatplane|Floats]] for water operations are an option.<ref name="serenityaviation2"/><ref name="Incomplete" /><ref name="serenityaviation3">{{cite web |url=http://serenityaviation.com/home/index.php?option=com_content&task=view&id=30&Itemid=40 |title=Introduction |publisher=Serenity Aviation |date= |accessdate=2012-08-22 |archive-url=https://archive.today/20130208183703/http://serenityaviation.com/home/index.php?option=com_content&task=view&id=30&Itemid=40 |archive-date=8 February 2013 |url-status=dead }}</ref><ref name="serenityaviation4">{{cite web |url=http://serenityaviation.com/home/index.php?option=com_content&task=view&id=27&Itemid=37 |title=Specifications |publisher=Serenity Aviation |date= |accessdate=2012-08-22 |archive-url=https://archive.today/20130208182243/http://serenityaviation.com/home/index.php?option=com_content&task=view&id=27&Itemid=37 |archive-date=8 February 2013 |url-status=dead }}</ref>

The Karatoo can accept engines in the range of {{convert|50|to|100|hp|kW|0|abbr=on}}, depending on the model. Engines used include the {{convert|50|hp|kW|0|abbr=on}} [[Rotax 503]] and the {{convert|64|hp|kW|0|abbr=on}} [[Rotax 582]] [[two-stroke]]s as well as the {{convert|80|hp|kW|0|abbr=on}} [[Rotax 912UL]], the {{convert|100|hp|kW|0|abbr=on}} [[Rotax 912ULS]], {{convert|85|hp|kW|0|abbr=on}} [[Jabiru 2200]], {{convert|71|to|100|hp|kW|0|abbr=on}} [[Subaru EA engine]], {{convert|90|hp|kW|0|abbr=on}} [[Continental C-90]] and the {{convert|100|hp|kW|0|abbr=on}} [[Continental O-200A]] [[four-stroke]] powerplants.<ref name="serenityaviation2"/><ref name="serenityaviation3" /><ref name="serenityaviation4" />

In 1988 the J6 design was adapted to the [[Ultralight aircraft (Canada)|Canadian ultralight rules]] as the [[Norman Aviation J6 Karatoo]] and, in 1990, as the [[Buzzman L'il Buzzard]].<ref name="KitplanesDec1998" /><ref name="Cliche" />
