Design

The aircraft´s design is a result of long and careful developing phase conducted by the TL-ULTRALIGHT company.

The Sting S4 is a composite aircraft with engine located in the front. The primary structure contains 85% of carbon fiber for maximum strength and weight saving. The wing skin and fuselage is a sandwich of carbon and foam core, glued together with epoxy glue. The coating is then evacuated and cured in an oven. Highly stressed parts are made in an autoclave. High safety carbon frame with ROPS ensures crew safety, even in the case of the aicraft being overturned. Varnishing is done using white dual-component paint. The final design touches are made by vinyl foil covering.

Engine

Engine is the heart of every aircraft, and that is why all our aircraft are fitted with engines of the ROTAX brand - they have been tried, they have been tested and come with thousands of flight hours experience.

Standard aircraft fitting includes: Rotax 912 (80 hp), 912S (100hp) or 914 turbo. It is now possible to equip your aircraft with the 912iS engine with a fuel injection system. Propeller can be fixed or in-flight adjustable. You can choose from a wide variety of types and designs. The ideal choice of course is the in-flight adjustable PowerMax propeller.

  • ROTAX 912 ULS

    The Rotax 912 ULS is a four-cylinder, four-stroke engine, with liquid cooled cylinder heads and air-cooled cylinders. It has got a dry sump forced lubrication with a separate oil tank of 3 liters, automatic adjustment by hydraulic valve tappet, 2 carburetors with constant pressure in the diffuser, mechanical fuel pump, contactless electronic dual ignition with two circuits, electric starter and propeller speed reduction unit i = 2.43.

  • ROTAX 912 iS

    The Rotax 912 iS was developed on the basis of the 100 hp Rotax 912 ULS engine. The main difference between 912iS and 912 ULS is substitution of carburetors for preparing mixture with dual, electronically operated fuel injection system. Other changes include oil pump reinforcement and increase in generator performance.

    It is a four-cylinder, four-stroke engine with liquid-cooled cylinder heads, air-cooled cylinders, dry sump lubrication with a separate oil tank, automatic adjustment by hydraulic valve tappet, electronic dual fuel injection, electronic engine management (EMS), electric starter, propeller speed reduction unit and an engine suction system.

  • ROTAX 914

    The Rotax 914 is a four-cylinder, four-stroke engine with liquid-cooled cylinder heads and air-cooled cylinders, with a turbocharger and a pressure relief valve. It has got dry sump lubrication with a separate three liter oil tank, automatic adjustment by hydraulic valve tappet, two carburetors with constant pressure in the diffuser, mechanical diaphragm fuel pump, contactless electronic dual ignition, electric starter, propeller speed reduction unit i = 2.43 with overload clutch, motor mount, suction chamber and stainless steel exhaust.

  • PowerMax Propeller

    The PowerMax is a three-blade tractor in flight adjustable aircraft propeller. The aluminum alloy hub consists of top and bottom flange with lid. The blade adjustment mechanisms are located inside the hub. Increasing of the blade angle is done by the actuator. For the opposite direction, the blades are adjusted through the resistance of spring located inside the hub. The carbon fiber blade has got an aluminum alloy root part and is mounted onto the hub by a pair of axial bearings. The actuator is located outside the hub, above the engine reduction unit, and controls the blade adjustment by a hollow axis of the reduction unit and the propeller.
