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.{{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}}{{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 }}{{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}}
The aircraft features a cantilever wing, a T-tail, a two-seat side-by-side enclosed cockpit under a bubble canopy, fixed tricycle or conventional landing gear with a steerable tail wheel and a single engine in tractor configuration.
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 flaperons with spoilers or optionally ailerons and dive brakes. 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 tips for 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.{{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}}{{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}}
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.
