The wing is comprised of a single one piece laminated wooden spar with a
moulded plywood leading edge forming a torsion box, completed in conventional
fashion with wooden ribs and fabric covering aft from the torsional box.
Differential, slotted ailerons are fitted together with hand operated slotted flaps
extending from the root fillets to the inboard ends of the ailerons.
The flaps are constructed in wood and fabric.

DESCRIPTION
Undercarriage
Tailwheel type. The conventional two-wheel cantilever non-retractable
undercarriage is secured direct to the wing. The tailwheel is mounted on a
quarter elliptical leaf spring and is connected by springs to the rudder to eliminate
shimmy and to assist in turning.
External disc type hydraulic brakes are fitted.
Empennage
A single fin and rudder, streamlined with the bottom of the fuselage is
used. The empennage is completed by a cantilever tailplane and elevators.
Anti-spin strakes extend forward along both sides of the fuselage from the
inboard ends of the tailplane.
