Technical Details

The cantilever tapered backswept wing of an angle of 5,5° with SM 701 airfoil along the whole span is a reinforced shell of carbon composite sandwich with carbon composite coating. The main spar is made of laminated hard beech wood saturated with synthetic resin. Highly effective slotted flaps had been developed using the sophisticated calculation methods. Its control can be either mechanical or electrical.

The fuselage is all-carbon composite shell braced with carbon sandwich bulkheads, NOMEX honeycomb & hardened foam. The cross-section is elliptic with pure wing fillets & a spacious cabin. The engine in the front part of the fuselage is separated from the cockpit by the firewall, to which the engine mount & steerable nosewheel are attached.

The tail unit is all-carbon composite T-shaped construction which consists of tapered horizontal tailplane with fix stabilizer & elevator. The elevator trim can be either mechanical or electrical. The tapered tail fin is an integral part of the fuselage. The rudder is suspended to the last fuselage bulkhead.

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 tested for the load of 550 kg. The integral nose leg is made of composites & metal tube with shock-absorbing rubber springs. The main wheels are equipped with hydraulic disc brakes. The electronic main wheels size is 350×120 mm, nose wheel size is 300×100 mm. Aerodynamic fairings are installed on all wheels.

The steering of all controls is dual. Ailerons, flaps & elevator are controlled by rods & levers, the rudder is controlled by stainless steel wire ropes. All controls are designed the way not to disturb the pure outline profile of the airframe. Important checking points in wings are equipped with inspection holes with perspex covering.

We standardly install ROTAX 912iS SPORT 100HP, ROTAX 912 ULS 100 HP or ROTAX 912 UL 80 HP engines in configuration with three- or two blade FITI propeller, which can be fix, ground adjustable or adjustable in flight, with manual or electric control & availability of Constant speed system.

The fuel system consists of two fuel tanks in wings with a total fuel capacity of 100 litres (2 x 50L). All the fuel system is installed outside the cockpit area. The piping connection is equipped with a sediment bowl & a drain plug. The fuel supply is secured by two independent circuits & pumps. The fuel pressure is monitored by the pressure gauge. The previous aircraft version having only one central fuel tank (capacity 70 L) integrated in the fuselage is still available upon request.

Instruments provide a wide range of alternative custom solutions. We offer basic analogue instruments or the most advanced glasscockpit electronic systems for the flight & engine monitoring (EFIS, EMS) & navigation up to the screen size of 9 inch, USB connector, MP3 & movie player. The plane can also be equipped with position recorder, 3-axis autopilot, various types of GPS, radios, transponders, ELT, stall warning etc… The static & dynamic pressure is taken from the Pitot tube installed on the underside of the left wing. The dashboard is standardly equipped with 12V plug & USB connector for your iPad.

Whole the cockpit is upholstered with a special fabric containing nanofibers. The advantage of such smooth, comfortable material is its easy cleaning, high resistance, long life-time & surely also its light weight. It is available in various colours & their combination is individually customized. We offer two types of ergonomic seats. The standard „car“ seats are easily adjustable up/down. The second type consists of carbon shell with removable cushions attached on Velcro. The cushions thickness is customized. This type is adjustable forward/backward using the lever mechanism on its underside. The pedals are adjustable in 3 positions. The cockpit can be optionally equipped with the second control stick on passenger’s side. The side walls are fitted with armrests & net pockets. The spacious luggage compartment behind the seats is easily accessible during the flight. Its loading capacity can be optionally increased by the modification of the space behind the pilot´s seat. Two ventilators installed on the dashboard assure effective air-ventilation & heating. The floor on passenger’s side is adapted the way to provide a higher comfort also to the legs.

The canopy is made from Perspex containing UV filters. Both sides are fitted with small sliding windows. It is offered in colourless or tinted versions. Demisting fan on the top of the dashboard helps to keep good visibility. The canopy opens up- & backwards. Electrical blocking system disables to start the engine in case the canopy is not properly closed & locked. Mechanical blocking system prevents from self-opening during the fl
