Sinus 912 LSA is a 49 ft (14.97 m) wingspan, two-seat T-tail motorglider made almost entirely of composite materials. Its low-drag, high-wing-monoplane, engine-at-the-front construction makes it efficient even when flying unpowered. In fact, the propeller can be feathered to reduce drag even more.
The undercarriage is a tricycle type with two main, brake equipped, wheels mounted on struts and a steerable nose wheel.
Sinus 912 LSA features flaperons, interconnected flaps and ailerons presented in the same deflecting surface. Flaps offer 4 settings: neutral, 1st, 2nd and the negative (reflex) position. Full dual main flight control levers make Sinus 912 LSA ideal for initial as well as for advanced flight training. All aileron, elevator and flap controls are connected to the cabin controls using self-fitting push-pull tubes. Rudder is controlled via cables. The elevator trim is mechanical, spring type.
Airbrakes are available as standard, they reduce the requirements for runways size for landing and provide for steeper approaches and expedite descents.
All aircraft ship with H type safety belt attached to the fuselage at three mounting points. Rudder and brake pedals can be adjusted also during flight to suit your size and needs.
Fuel tanks are located inside the wings. Fuel selector is in the form of two separate valves, located on the left and right upper wall of the cabin. The gascolator is located beneath the lower engine cover.
Refuelling can be done by pouring fuel through the fuel tank openings on top of the wings or by using an electrical fuel pump. All glass surfaces are made of 2 mm anti UV GE tinted Lexan, which was specially developed not to shatter or split on impact.
Main wheel brakes are hydraulically driven disc type. The hydraulic brake fluid used is DOT 3 or DOT 4.
Cabin ventilation is achieved through special vents fitted onto glass doors, cabin heating, however, is provided utilizing hot air from the engine.
To enhance aerodynamics even more, every Sinus 912 LSA comes equipped with special wheel fairings and the propeller spinner. The propeller is a ground adjustable composite two blade design.
The electric circuit nables the pilot to test individual circuit items and to disconnect the entire wiring but leave the engine running, should there come to a distress situation. Navigational (NAV), anti collision (AC) and landing (LDG) lights are an option. The firewall is reinforced by heat and noise insulation.
Basic instruments come installed with operational limits pre-designated, advanced avionics in form of EFIS glass cockpits etc. are an option. Parachute rescue system is an option. Optional is the also the side access door to the cargo compartment behind the seats.
