Its wing is of trapezoidal plan with blunt tips, constructed from two metal spars and stressed aluminium skin.

Inboard of the ailerons, which are fabric covered over aluminium alloy frames and mass balanced, there are hydraulically operated split flaps.

The horizontal tail, mounted on the top of the fuselage, is also straight tapered with blunt tips but the fin and rudder are more rounded, with a long dorsal fillet reaching forward to the rear of the cockpit glazing.

Student and instructor occupy tandem cockpits fitted with dual controls under individual sliding sections in the continuous glazing.
