Design and development
The Ultra was designed as a highly efficient aircraft, to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.
The aircraft is made from composites. Its {{convert|11|m|ft|1|abbr=on}} span wing employs a Wortmann FX 66-17All-182/26 airfoil, has an area of {{convert|12.10|m2|sqft|abbr=on}} and flaps that have deflections of 0°, 15° and 35° available. The standard engine provided is the {{convert|85|hp|kW|0|abbr=on}} Jabiru 2200 four-stroke powerplant.{{cite web |url=http://www.protoplane.net/en-technicaldata.html |title=Protoplane technical data |publisher=protoplane |date= |accessdate=2012-08-23 |url-status=dead|archiveurl=https://web.archive.org/web/20120408093107/http://www.protoplane.net/en-technicaldata.html |archivedate=2012-04-08 |df= }}
The Ultra achieves a fuel economy of 12L/h (43 mpg) at 220 km/h (137 mph) through aerodynamic refinements and use of composites.{{cite web |url=http://www.protoplane.net/en-mainfeatures.html |title=Protoplane main features |publisher=protoplane |date= |accessdate=2012-08-23 |url-status=dead|archiveurl=https://web.archive.org/web/20090406171354/http://www.protoplane.net/en-mainfeatures.html |archivedate=2009-04-06 |df= }}
