The LH-10 Ellipse was conceived by Frenchman Sébastien Lefebvre, starting as an engineering grande école (university) project to conceive "a small plane with different design and performance than available for private pilots" [REF].
In February 2010, the aircraft began a series of tests required to achieve the French CNSK standard (an acromym for Certificat de Navigabilité Spécial Kit, the French kitplane certification).
