SZD IS-2 Mucha

The SZD-22 Mucha Standard Standard Class single-seater had its origins in the IS-2 Mucha (or Fly) intermediate single-seater of 1948, which was produced in several versions and used in some numbers by the Polish gliding clubs; the Mucha-ter set up several national records for altitude and distance, and the type achieved several Diamond C flights. The IS-2 Mucha had a single-spar high wing with an aspect ratio of 15, and was fitted with dive brakes and spoilers; the fuselage was of elliptical cross-section. The Mucha-ter was developed into the SZD-12 Mucha 100 of 1953, this single-seater being used for training. It was of all-wood construction, the cantilever high wings having a single main spar and an oblique auxiliary spar, with a plywood-covered leading edge torsion box; air brakes were fitted and the ailerons were aerodynamically and mass balanced. The oval-section fuselage was plywood-covered and the pilot sat under a onepiece Plexiglas canopy. Landing gear consisted of a monowheel and short front and rear skids sprung with rudder pads.

Szaraz SDS-1A Daphne / SD-1A Daphne

Evolved from the Vidervol-Szaraz VS-1, the Szaraz SD-1A Daphne is a homebuilt aircraft that was designed by Art Szaraz and Bernie Darmstadt for efficiency competitions.

The Daphne is a two place side-by-side configuration strut-braced high-wing, conventional landing gear equipped homebuilt. The fuselage uses welded steel tubing with aircraft fabric covering. The wings are wood, with one-piece plywood ribs. Both ailerons and flaperons have been installed on the design.

The first three examples were built on the same jigs at Art Szaraz’s workshop. At least fifteen were built. At least 26 were under construction by Jan 1970.

Known examples:
N960Z (c/n 1) built by Arpad Szaraz, ff: 1963
N962Z built by Nick Stanich, ff: 2/28/65
N961Z built by B D Darmstadt, ff: 6/18/65
