Design and development
The RG-5 Pescăruș was a single seat glider designed and built in Romania in the 1950s, intended for club use. It was a mid wing cantilever monoplane. Like the rest of the aircraft, the wing was wooden, built around a single spar and mounted with 1.66° of dihedral. Plywood skinning from the spar forward and around the leading edge formed a torsion box; the rest of the wing was covered with a mixture of ply and fabric. In plan the wing was symmetrically straight tapered, with squared tips, where there were small tip bodies or plates. It had wood framed, fabric covered, balanced ailerons which reached out to the wing tips. DFS (Schempp-Hirth) type airbrakes were mounted at mid-chord, just inboard of the ailerons. There were no flaps.
The RG-5 had a ply monocoque fuselage with its single cockpit ahead of the wing, enclosed by a multipart, sideways opening canopy which reached to the nose. It landed on a fixed monowheel under mid-wing, with a skid that reached from the nose to under the leading edge, assisted by a small tail bumper. The fuselage tapered markedly from the cockpit aft to a conventional wooden framed, fabric covered empennage. Both tailplane and fin were straight edged, with the former mounted forward of the fin at shoulder position and carrying rounded elevators. Together the fin and rudder were flat topped. The rudder hinge was at the trailing edge of the elevators, leaving the rudder, broad and straight edged to its rounded heel, clear to extend down to the keel.
The RG-5 Pescăruș was first flown on 8 September 1957. 26 were produced, going to Romanian gliding clubs.
