Design and development

The TST-5 Variant features a strut-braced shoulder-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.[1]

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.[1][2]

The manufacturer estimated the construction time from the supplied "express-built" kit as 250 hours.[1]
