Description

Single-seat, single-engine high-wing (no struts) airplane. Front-wheel (steerable) nonretractible undercarriage. Horizontal tail unit is mounted on the rear fuselage. Full metal (Al 6061) airframe, fiberglass main landing gear leg.

The trapezoidal wing is twisted both aerodynamicly and geometricly . The two-spars construction is supplemented with two longitudinal stringers. Transverse construction consits of ribs. The wing is equipped with slotted flaps and ailerons on the trailing edge and integral fuel tanks in the leading edge.
Installing the wing to the fuselage is realized by means of a center wing section (firmly embedded in the fuselage) and beam hangers.

Fuselage is of a rectangular shape with round edges in the engine and cabine areas. The rear part is round. Construction is half-shell structure with longitudinal stringers and bulkheads.

Empennage is standard. The horizontal tail unit is mounted in the fuselage with a straight trailing edge. The vertical stabilizator is swept backward.

Control system is made of push/pull tubes (elevator and aileron) and steel cable (rudder). Flaps are extendend manualy by a lever. The wheels of main landing gear are equiped with hydraulic brakes.

Undercarriage is classical three wheels with steerable front wheel. The main landing gear leg is running fiberglass construction built in the fuselage.
