Flight Design General Aviation GmbH is an aerospace company and aircraft manufacturer based in Eisenach, Germany. It was founded by Matthias Betsch in 1988 and originally focused on producing hang gliders, paragliders, and ultralight aircraft. In March 1996, the company introduced the CT series and began its production in 1997. Today, the CT series can be flown under Microlight/Ultralight regulations in many countries and SLSA rules in the US and countries that use the ASTM standards for compliance.
In February 2011, the company announced the development of a four-seat aircraft designated C4. However, in February 2016, the company entered receivership due to its high debt-load. Lift Air, a division of Lift Holding, acquired the Flight Design-Design organization, the production facility in Kherson, and all rights to the CT series (CTSW, CTLS, CTSL Supralight, CTLSi, CTLE) in July 2017. The company has since moved to the Kindel Airport near Eisenach, where final inspection, test flights, and engineering management are conducted. In 2019, Flight Design introduced two new models, the F2 and F4, with the F4 being a four-seat airplane powered by a Rotax 915iS turbocharged engine. The company also announced a modular design for the F2 that would include a future electric aircraft variant, designated the F2e. The company continues to work on the Flight Design C4.
