7.1.Wing
The cantilever tapered wing with conventional ailerons, slotted flaps and wing-tips. The main spar of laminated beech wood saturated with synthetic resin at a high temperature is placed in the 30% depth of wing. The wing skin is made of carbon sandwich. The wing is reinforced by ribs of plastic and composites, the root ribs are of carbon – nomex honeycomb sandwich. Ailerons and flaps are of all composite construction. The centre-wing section is welded from high quality CrMo steel tubes.
7.2.Fuselage
The fuselage is an all-carbon composite shell reinforced by bulkheads. The fuselage cross- section is elliptic, with wing fillets and spacious cockpit. The cockpit enclosure is from organic glass and it is lifted up and to the right. The engine space in the front part of the fuselage is separated by a firewall. The engine bed is fastened to a fire-proof engine bulkhead.
7.3.Tail Surfaces
The conventional tail surfaces are of all carbon composite construction. The horizontal tail surface has a trapezoidal shape formed by a rigid stabiliser and elevator. The vertical tail surface and the rudder have a trapezoidal shape. The tail unit is an integral part of the fuselage.
7.4.The Landing Gear
The landing gear is a fixed two-wheel undercarriage with a controllable tail wheel. The main landing gear is formed by a pair of composite flat springs. Main wheels of dimensions 350 x 100 mm are covered by aerodynamic fairings and are equipped with disc brakes hydraulically controlled.
7.5.Control
The ailerons, elevator and the flaps are controlled with the help of pushrods and levers, the rudder with the help of steel wire ropes. Important check points have inspection openings overlapped by organic glass. No part of control system interferes exterior of the airframe.
7.6.The Driving Unit
The driving unit is the engine ROTAX 912 UL 80 HP and the two-blade ground adjustable propeller FITI ECO COMPETITION.
