TL-Ultralight s.r.o.

The first series of test flights of the carbon fiber composite TL-3000 Sirius has been completed. This is a major milestone for the all new high wing sister ship to the Sting. Piloted by TL-Ultralight founder and president, Jiri Tlusty, the much anticipated Sirius displayed very responsive low speed handling and docile flight characteristics.

Like the Sting, the Sirius will be powered by the ROTAX series of aircraft engines and be available in an ULM and LSA version. A wide variety of standard flight and engine monitoring instruments to full glass panel displays will be available. With its large cockpit offering ample head and leg room, feedback from those who have had a chance to take a first look has been very positive.

Another round of flight tests will be completed soon, after which more data will be available. Check back regularly, as we will be updating this page with information as it becomes available. As we are now taking orders, please contact your local dealer or us directly at sales@ul-ultralight.cz to reserve your position today.

In April 2010, we introduced a new generation of  the successful type called the TL 2000 Sting S4. During design and construction works we have combined the successful and well-established aircraft construction proven by more than 350 pieces manufactured,  with new features which improved the flight characteristics of the aircraft and increased the comfort including the user's cosiness. The Sting S4 has become aerodynamically clean and it is unachievable in its class due to the elegant appearance. We have gathered 10 years of production experiance of the TL 2000 Sting Carbon and we have listened to all comments from pilots who flew the previous model for hundreds of safe flight hours. Primarily, we have tried to adapt the new S4 model to your needs, our valuable customers! Pilots who operated the model Sting Carbon praised it but they could always find some little things that they would improve as users of the aircraft. From all these observations and feedbacks and after careful development,   the new Sting S4 was born.

The TL 2000 Sting S4 is a two-seater low-wing aircraft, made from carbon fiber, powered by engine mounted in the front. Seating is side-by-side. The Sting S4 complies with all aspects of the Light Sport Aircraft (LSA - 600kg) ASTM standards and as well of UL2  standards of ultralight aircraft (ULM - 450kg). The new Sting S-4 improvements and aerodynamic modifications make it more than compatible with the Sting RG model which has retractable landing gear.

The Sting S4 is currently one of the fastest and best-handling czech ultralight aircraft on the market. This sport and cruising aircraft is suitable for all age categories. It ensures excellent enjoyment from flying. Its maximum speed in level flight is around 285 km / h (154 kn). Speed range of the Sting S4 is from the stalling speed 63 km / h (34 kn) up to never exceed speed 305 km / h (165 kn).

The newly  designed Sting S4 grabs you and doesn´t let go. The aircraft turned heads at every airport because of it  's like curious design. The most striking feature of the cockpit is the panoramic, 360º view. The excellent cabin view as well as the low noise level contribute to the well-being feeling and comfort which is unexpected in this category of aircraft with the sense of freedom being enhanced by a considerable aircraft climb. The cabin consists of a single piece plexiglass canopy, which opens upwards and is supported by two piston rods. For the Sting S4 model the cabin has been redesigned to achieve better appearance. The cockpit is heated for better pilot comfort and new ventilation has been added to the canopy frame to prevent fogging. Other new S4 face lift features include new handles for opening the canopy, which provides more comfortable, easier opening and give better overall impression. For convenient luggage transportation the luggage compartment has been extended to 25 kg (55 lb) load. Primarily we have been focusing on providing better piloting and easy access for pilot and passenger.

Inside the cabin the pilot can feel at home. The cabin is sufficiently spacious and all flight instruments and switches are well-arranged in the pilot's field of vision. Everything is easily accessible even with your seat-belts fastened. The Sting model S4 was fitted with new ergonomic panel layout where the instrument space has been extended to accommodate the IFR glass cocpits. The new layout of the instrument panel facilitates a quick and easy scan. To make your piloting even more pleasant the bottom edge of the panel board has been moved up to create more room for legs.

The aircraft is equipped with the complete dual control system. For the aircraft operation there are two standardly configurated control sticks offering maximum effeciency. New adjustable rudder pedal system now allows you to move the pedals in the range of 220 mm. The tricycle landing gear system is fitted with new design main wheel brakes. The front undercarriage leg is now uncontrolled which significantly improves the characteristics of the airplane in the air. The nose gear design has also been completely changed and became more aerodynamicly clean and more elegant. Electricaly operated flap control system offers two flap possitions. One for take off at 15 ° and the second for landing at 35 degrees.

The Sting S4 is standardly equipped with the Rotax 912 (80hp), as option with 912ULS (100HP), or 914 turbo (115HP). You can choose from wide range of propellers, either fixed on the ground or adjustable in flight. The propeller can also be supplied with a metal blade protection. Instruments and devices, such as GPS, or the latest glasscockpit can be ordered according to customer's needs. The aircraft can also be fitted with a ballistic rescue system, which saves the crew and the whole plane in a case of an emergency.

We introduced this model for the first time at the world exhibition AERO 2010 in Friedrichshafen, Germany. New design and modifications reaped great success there. The Sting S4 is suitable for pilot training, leisure flying and thanks to the speed also for business trips. We hope that you will become one of the happy owners of this new aircraft.

The Sting RG offers a ground breaking optional in flight adjustable propeller which is electronically controlled needing no pilot input normally only available on aircraft costing hundreds of thousands.

The Whole Aicraft is made from Carbon Fibre. The elegant and perfectly aerodynamically shaped TL-2000 Sting RG was designed to achieve the highest speed of flight.

The Sting RG really is the fastest Czech Ultralight and its maximum speed in horizontal flight of about 285 km/h and its not definitely the last word. Interresting is also speed of flight from minimum 63 km/h to insuperable speed 305 km/h which gives pilots of all abilities the opportunity to operate within their skill levels and to fly from grass strips or tarmac.

The Sting S3 complies with all aspects of the Light Sport Aircraft (LSA) ASTM standards. These ASTM standards specify the design and performance requirements of two types of LSA aircraft, Special Light Sport Aircraft (SLSA) and Experimental Light Sport Aircraft (ELSA). SLSA aircraft are production-models of completed, ready-to-fly aircraft. ELSA aircraft are 99% complete kit versions of SLSA aircraft and are in effect 'clones' of the certified S models.

Our first SLSA aircraft was certified in April of 2005. A new factory has just been completed for the US production market to assure our customers of a constant flow of aircraft. The demand for the S certified model has been strong and we are now able to launch from four to six aircraft per month. FAA certification for our thirty-second StingSport SLSA was just completed and N912N was delivered to our new customer from Vacaville, CA.

With our emphasis on your safety, features such as an internally mounted ballistic parachute aircraft recovery system, a no- corrosion, low-maintenance airframe and a one piece canopy, are standard with each plane. The canopy provides a 360° panoramic view and low noise levels to create a professional cockpit with both comfort and style. In addition, all controls and flight instruments have been ergonomically positioned to maximize ease of use. The wings can be removed in about 15 minutes for easy transport and storage. Additionally, the StingSport includes a 3-blade, ground-adjustable propeller as standard equipment.

Rotax four cycle, four cylinder engines have been tested and approved for installation on our aircraft. The standard engine is the Rotax 80 hp 912. The more powerful 100 hp 912ULS has proven to be the most popular available option. Our option list is short, these are already well-equipped aircraft. But we are always testing new products; a ballistic chute has been standard since our first aircraft. Currently we are the only sport aircraft to offer you FAA approved airbags on our safety harness. We invite you to visit us here on the web, at any of the major air shows around the country or see and fly the Sting S3 for yourself at any of our Regional or Satellite dealers listed on the the "Local Dealers" page.
