The Politechnika Warszawska PW-3 Bakcyl (Microbe) is a Polish primary glider developed from the PW-2 Gapa.
Originally these struts could pivot through 90° to act as airbrakes, as on the PW-2, but they were later replaced with upper surface spoilers, inboard of the ailerons and positioned immediately behind the spars.
A long, one-piece canopy reaches back to the rear seat which has a short, fixed glazed extension under the wing.
The Bakcyl lands on a fixed, fully exposed monowheel under the forward fuselage, aft of mid-chord, which has a shock absorber and a brake.
[1][3][4] The Bakcyl's tail is conventional and similar to that of the PW-2, with a rectangular plan, canvas-covered tailplane mounted on top of the end of the tailboom and carrying a one-piece, narrow-chord elevator.
