==Design and development== The Lambada was designed to comply with the [[Fédération Aéronautique Internationale]] microlight rules at a gross weight of {{convert|472.5|kg|lb|0|abbr=on}} and US [[light-sport aircraft]] rules at {{convert|600|kg|lb|0|abbr=on}}. The design is on the [[Federal Aviation Administration]]'s list of approved special light-sport aircraft.<ref name="WDLA11" /><ref name="SLSA">{{cite web|url = http://www.sportpilot.org/learn/slsa/|title = EAA's Listing of Special Light-Sport Aircraft|accessdate = 1 June 2012|last = [[Experimental Aircraft Association]]|year = 2012|archive-url = https://web.archive.org/web/20140228070151/http://sportpilot.org/learn/slsa|archive-date = 28 February 2014|url-status = dead}}</ref><ref name="FAASLSA">{{cite web|url=http://www.faa.gov/aircraft/gen_av/light_sport/media/SLSA_Directory.xls |title=SLSA Make/Model Directory |accessdate=6 December 2012 |last=[[Federal Aviation Administration]] |date=12 October 2012 |url-status=dead |archiveurl=https://web.archive.org/web/20130516004527/http://www.faa.gov/aircraft/gen_av/light_sport/media/SLSA_Directory.xls |archivedate=16 May 2013 }}</ref><ref name="Lambada">{{cite web|url = http://www.sambaxxl.com/index.php?option=com_content&view=article&id=4&Itemid=3&lang=en|title = Airplane Lambada|accessdate = 6 December 2012|last = Distar|year = 2010}}</ref>

The aircraft features a cantilever wing, a [[T-tail]], a two-seat [[side-by-side configuration|side-by-side]] enclosed cockpit under a [[bubble canopy]], fixed [[tricycle landing gear|tricycle]] or [[conventional landing gear]] with a steerable tail wheel and a single engine in [[tractor configuration]].<ref name="WDLA11" /><ref name="Lambada" />

The aircraft is made from composites. Its {{convert|13|m|ft|1|abbr=on}} span wing employs a SM 701 [[airfoil]], has an area of {{convert|12.16|m2|sqft|abbr=on}} and [[flaperon]]s with [[Spoiler (aeronautics)|spoiler]]s or optionally [[aileron]]s and [[dive brake]]s. Flaperon settings are 0°, 5°, 9° and 16°, with the last setting assisted by the spoilers. The wings can be extended to {{convert|15|m|ft|1|abbr=on}} with [[wing tip]]s for [[gliding|soaring]]. The main [[landing gear]] legs are fabricated from [[fibreglass]] laminates and the wheels are equipped with single lever hydraulic brakes. Standard engines available are the {{convert|80|hp|kW|0|abbr=on}} [[Rotax 912UL]] and the {{convert|85|hp|kW|0|abbr=on}} [[Jabiru 2200]] [[four-stroke]] powerplants.<ref name="WDLA11" /><ref name="Lambada" /><ref name="Incomplete">{{Cite web|url = http://www.ae.illinois.edu/m-selig/ads/aircraft.html|title = The Incomplete Guide to Airfoil Usage|accessdate = 3 January 2012|last = Lednicer|first = David|year = 2010|archive-url = https://web.archive.org/web/20100420012244/http://www.ae.illinois.edu/m-selig/ads/aircraft.html|archive-date = 20 April 2010|url-status = dead}}</ref><ref name="Specs">{{cite web|url = http://www.sambaxxl.com/index.php?option=com_content&view=article&id=21&Itemid=32&lang=en|archive-url = https://archive.today/20130202022535/http://www.sambaxxl.com/index.php?option=com_content&view=article&id=21&Itemid=32&lang=en|archive-date = 2 February 2013|title = Technical data|accessdate = 6 December 2012|last = Distar|year = 2010|url-status =dead}}</ref>

The aircraft achieves a 26:1 [[glide ratio]] with 13 m wings and 30:1 with 15 m wings fitted. Aside from its use as a motorglider, the Lambada has also been successfully employed as a [[glider tug]].<ref name="WDLA11" />
