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.[1]

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]

Variants

TST-5 Variant: Original model with constant chord, strut-braced wing[1]
TST-5 Variant Duo: Model with tapered cantilever wing[1]

gollark: Oh, so just big directional antennas, not satelliteuous things with LNBs and whatever.

gollark: I'm pretty sure those are mostly receive-only systems, or cost all money.

gollark: To commune with satellites?

gollark: Well, the best* way is to just shove mesh network hardware/software into literally all devices ever with no off switch.

gollark: What?
