Wing
The cantilever tapered backswept wing of an angle of 5,5° with SM 701 airfoil along the all span is a
reinforced shell of a carbon-fibre sandwich with a carbon-fibre coating. The wing spar is made of
laminated hard beech wood saturated with synthetic resin and is situated in 30% of wing depth. The
ailerons are hinged on the rear spar and slotted flaps are hinged on fiberglass hinges. Ailerons and
flaps are made of all composite structure. Wing root ribs are made of carbon sandwich, other ribs
are of plastic foam. The main spar is welded of high quality CrMo steel tubes.
7.2.
Fuselage
The fuselage is all composite carbon-fibre shell braced with carbon sandwich bulkheads, NOMEX
honeycomb and hardened foam. The fuselage cross section is of elliptic shape with a spacious
cockpit and aerodynamic wing bases. In the front part of the fuselage is the engine separated from
the cockpit by fireproof wall to which the engine mount and the steerable nosewheel are fixed. The
cockpit is covered with the canopy. The luggage compartment with two small side-windows behind
seats are the part of the cockpit.
7.3.
Tail Surface
The T-shaped tail surface construction consists of tapered vertical and horizontal tail with fix
stabilizer and elevator. The elevator trim can be mechanical or electrical. The tail fin is an integral
part of fuselage. The rudder suspended to the last fuselage bulkhead is made of fiber-glass.
7.4.
The Landing Gear
The landing gear is a fixed tricycle undercarriage with a steerable front wheel. main gear is
constructed as a pair of leaf springs of composites. The front leg is made of composites and metal
tube suspended with rubber spring. The main gear is a pair of composite springs. Electronic main
wheels size is 6´´ 4.00x6-6PR, front wheel size is 4´´ 4.00x4-6PR. The main wheels are equipped with
hydraulic disc brakes. Fairings are installed on all wheels.
7.5.
Steering
The steering of all control surfaces is duplicated. The ailerons, flaps and elevator are controlled by
control rods and levers, the rudder is controlled by steel wire ropes. Lift flaps are optionally
equipped with electrical control. All control attachments are situated as to not interfere with the
airframe contour. The important checking points in wings are equipped with inspection holes with
perspex covers.
7.6.
Propulsion
The standard option of propulsion is ROTAX 912 iS Sport 100 HP engine and three or two blade FITI
ECO COMPETITION propeller, which is ground adjustable.
