7.1.
Wing
The cantilever tapered backswept wings with combined structure, slotted lift flaps and composite coating
have SM 701 airfoil along the whole span and winglets on wingtips. The main spar is made of laminated
hard beech wood saturated with synthetic resin and is situated in 30% of the wing depth. Ailerons are
hinged on the rear spar. Flaps are hinged on composite hinges with turning point under the outline profile.
Root ribs are made of carbon sandwich, other ribs are made of plastic foam. The wing coating is made of
carbon sandwich. Ailerons and flaps have all-composite structure. The centrewing is welded of CrMo steel
tubes of high quality. Inside the wing, in the area of leading edge are installed fuel tanks with the capacity
of 50L each.
7.2.
Fuselage
The fuselage is full-carbon composite shell braced with carbon sandwich bulkheads, NOMEX honeycomb
and hardened foam. The fuselage cross section is elliptic with aerodynamic wing base and spacious cockpit
covered by perspex canopy. The luggage compartment with two small side-windows behind the seats is a
part of the cockpit. The engine compartment in the front part of the fuselage is separated from the cockpit
by the firewall to which the engine bed and the steerable nose wheel are mounted.
7.3.
Tailplanes
The tailplanes have all-composite structure designed in classical cross tail arrangement. The horizontal tail
has trapezoidal shape and consists of fix stabilizer and elevator. The vertical tail has trapezoidal shape.
The tail fin is an integral part of the fuselage and the VT rudder has all-composite structure. The elevator
trim can be mechanical or electrical (optional equipment).
7.4.
Landing Gear
The landing gear is a fixed tricycle undercarriage with a steerable nose wheel. The main gear is designed
as a pair of composite leaf springs and the wheels with the size of 350x120 mm. The integral nose leg with
aerodynamic fairing is made of composite structure and the metal tube with shock absorbing rubber
springs. Nose wheel size is 300x100 mm. All wheels have aerodynamic fairings. Main wheels are fitted
with hydraulic disc brakes.
7.5.
Steering
Each control surface has dual steering. Ailerons and elevator are controlled by pushrods and levers. The
rudder is controlled by steel wire ropes. Flaps are driven electrically. All controls attachments are
designed the way not to disturb airframe outline. Important check points in the wings are fitted with
inspection holes covered by perspex covers. The pitch angle can be trimmed in flight. The cockpit can be
optionally equipped with co-pilot control stick.
7.6.
Propulsion unit
The propulsion unit consists of ROTAX 912 iS engine and three or two blade FITI ECO COMPETITION
propeller, which can be either ground or in-flight adjustable.
