==Development== The Allegro has a [[strut]]-braced wing constructed from [[aluminum]], with [[fibreglass]] wingtips. The 2000 and 2007 variants have a 10:1 [[aspect ratio]] wing that tapers outboard of the [[Flap (aircraft)|flaps]], while the shorter-winged SW model has non-tapered wings. The wings are equipped with three-position electrically actuated flaps with positions for 0, 15 and 48 degrees for cruising flight, take-off and landing, respectively, on the 2000 model and −4.5, 15 and 48 degrees on the 2007 model. The [[ailerons]] are of a differential design. The [[airfoil]] is an SM 701.<ref name="Hunt" /><ref name="Specs">{{cite web|url = http://www.mcp.com.au/allegro/specifications.html|title = Allegro 2007 Model Specifications|accessdate = 2009-12-15|last = XAir Australia|authorlink = |year = 2009|archive-url = https://web.archive.org/web/20091007041917/http://www.mcp.com.au/allegro/specifications.html|archive-date = 2009-10-07|url-status = dead}}</ref>
The [[fuselage]] is constructed from [[Kevlar]]-reinforced fibreglass with steel tube reinforcement in the cockpit area. The seating is for pilot and passenger in side-by-side configuration, sharing a centre-mounted control stick. The landing gear is of [[tricycle gear|tricycle configuration]], with curved main gear legs made from fibreglass and a nosewheel mounted on steel tubes with rubber puck shock absorbing. There is also a shock-absorbing tail skid mounted under the [[fin]]. While the fin is fibreglass the [[horizontal stabilizer]], [[Elevator (aircraft)|elevator]] and adjustable [[trim tab]] mounted as a [[T-tail]] are all aluminum.<ref name="Hunt" />
The standard {{convert|55|L|USgal|0|abbr=on}} fuel tank is mounted under the floor, with wings tanks optional, bringing total capacity to {{convert|95|L|USgal|0|abbr=on}}.<ref name="Hunt" />
Engines available for the 2000 include the {{convert|100|hp|kW|0|abbr=on}} [[Rotax 912ULS]], {{convert|80|hp|kW|0|abbr=on}} [[Rotax 912UL]] and the {{convert|64|hp|kW|0|abbr=on}} [[Rotax 582]]. The 2007 model offers only the Rotax 912UL and ULS. A [[Gliding#Aerotowing|glider-towing]] kit is optional which allows towing gliders up to {{convert|500|kg|lb|0|abbr=on}} gross weight.<ref name="Hunt" /><ref name="Specs" />
The design of the Allegro 2000 model has been praised for its aesthetic appeal, good cockpit visibility, light controls, operating economics and value, wide speed range, range and payload as well as enjoyable flight characteristics. It has been criticized for its poor [[ergonomic]] accommodation for taller pilots and also for poor control harmony, with the elevator controls much lighter than the ailerons, which are in turn much lighter than the rudder pedals.<ref name="Hunt" />
The aircraft can be flown under the microlight/[[ultralight]] regulations of several countries as well as the USA [[FAA]] [[Light-sport Aircraft]] rules. In Canada the aircraft can be registered as a [[Basic Ultralight]] or [[Advanced Ultralight]].<ref name="Hunt" />
