The TeST TST-5 Variant is a Czech homebuilt aircraft that was designed and produced by TeST Gliders of Brno, introduced c. 1998. When it was available the aircraft was supplied as a completely assembled aircraft, without engine or instruments, and also as a kit for amateur construction.Purdy, Don: AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition, page 362. BAI Communications, 15 July 1998. {{ISBN|0-9636409-4-1}}
Design and development
The TST-5 Variant features a cantilever shoulder-wing, a single seat in enclosed cockpit under a plexiglass canopy, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.
The aircraft is of all-wood construction. Its constant-chord wing with a NACA 4415 airfoil is intended to give docile handling and is supported by "V"-struts. The standard engine used is the M-125 powerplant.{{Cite web|url = http://www.ae.illinois.edu/m-selig/ads/aircraft.html|title = The Incomplete Guide to Airfoil Usage|accessdate = 11 May 2014|last = Lednicer|first = David|year = 2010|archive-date = 20 April 2010|archive-url = https://web.archive.org/web/20100420012244/http://www.ae.illinois.edu/m-selig/ads/aircraft.html|url-status = dead}}
The manufacturer estimated the construction time from the supplied "express-built" kit as 250 hours.
