Politechnika Warszawska PW-4 Pelikan

Both had fibreglass-epoxy structures, with a high wing, a tailboom with a conventional tail and a forward fuselage with two seats in tandem under a long canopy.

Unlike the Bakcyl, no forward sweep was necessary because the weight of the engine moved the centre of gravity rearwards to the passenger's seat, allowing the Pelikan to be flown with that seat occupied or empty, so the central section of the wing was rectangular in plan and the long tips straight-tapered on both leading and trailing edges.

The tail was similar to that of the Bakcyl, with a tall, broad fin and smaller, fabric covered rudder, together trapezoidal in profile, and a smaller, low set, fin-mounted, rectangular plan horizontal tail at the extreme end of the tailboom, its one-piece elevator aft of the rudder.

[2][3] The Pelikan had fixed tricycle gear with mainwheels, equipped with brakes, on arched, cantilever, fibreglass-epoxy/spring legs from the lower fuselage[1][3] (though one photograph[2] shows an additional drag strut) and a smaller, steerable nosewheel.

It displayed at the 16th Meeting of Amateur Aviation Structures in Oleśnica in June 1997 and remained active until seriously damaged in an accident on 11 November 2012.
