TL 2000 Sting Carbon & the TL 2000 Sting Carbon Retractable (RG)

The TL 2000 Sting Carbon manufactured by TL-Ultralights in the Czech Republic is arguably one of the most exciting aircraft to enter the Australian market, period.

TL 2000 Sting Carbon Retractable (RG)

Manufactured as Type Certified Ultralight Aircraft, they enjoy freedoms around the world which come from this certification. In Australia the TL 2000 Sting Carbon can be registered with the RAA as a factory built aircraft or as a LSA aircraft and with CASA as a LSA aircraft which means the aircraft can be used for training, private hire or private operations.

The TL-Ultralight company has achieved unprecedented success with previous variants of the TL 2000 Sting Carbon and the now superseded TL96 Star with over 300* of each flying skies around the world (*Dec 2008). The TL 2000 Sting Carbon model has also achieved several world records with the FAI in the Microlight and Aircraft (C1a) up to 500 kgs categories.

From the moment you sit in the cockpit you feel there is something special about this aircraft - there is definitely nothing ordinary about this airplane. The cockpit is ergonomically designed and every control is right where you expect it. The pedals are adjustable and the cockpit comfortably seats persons with varying heights from over 6’ 3” down to around 5’. The large canopy offers superb views in every direction and the Rotax engines available in 80hp, 100hp or the turbocharged 115hp are ideally suited to the aircraft and provide outstanding take-off, climb and cruise performance when matched to the in-flight adjustable three blade propeller.

The TL 2000 Sting Carbon is supplied with a complete selection of basic flight and engine instruments from the factory but any additional equipment you require can be fitted by the factory during manufacture, from the very basic up to and including EFIS systems and auto pilots. Our highly competent team are there to help with every aspect of the aircraft delivery including your conversion and familiarisation flights. When the aircraft arrives, your dealer will assemble, test fly and provide up to 5 hours of familiarisation before setting you free to take to the skies in an aircraft which handles just like your own little fighter jet.

If on-field or hangar storage is a unavailable, then the wings can be easily removed by two people in less than 15 minutes and the aircraft can be stored in either a 20 foot shipping container or a trailer for storage at home.

The TL 2000 Sting Carbon as the name suggests, is constructed almost entirely of Carbon Fibre which is very easy to maintain and repair, should the need ever arise.

Large, Spacious and Ergonomic Cockpit

The comfortable, spacious cockpit makes you believe you're flying a much larger aircraft and the sleek, aerodynamic looks not only turn heads at every airport, but they also make the aircraft one of the quietest available. The low noise levels reduce fatigue and make this truly a 1,000 mile per day tourer. The optional long range tanks give over 8 hours endurance, which is more than enough to get to your destination.

The cabin heater keeps the pilot and passenger comfortable in even the coldest weather and also keeps the canopy clear in conditions which would normally make it fog up.

All performance figures and specifications are at a maximum takeoff weight of 544 kg as permitted by Australian RAA regulations, the aircraft however is approved for operations up to 600 kg in the LSA category.

Flying the TL 2000 Sting Carbon - My Flight Impressions

Taxi

The TL 2000 Sting Carbon aircraft offers superb visibility in all directions and allows for clear and confident manoeuvring in the taxi area.

Taxi speed should be low at just above a brisk walk however the aircraft is extremely stable even when doing high-speed taxis. Even at idle power the aircraft will roll and accelerate so throttle is not often required to taxi the aircraft once it is actually rolling. The nose wheel is directly connected to the rudder pedals and as such offers perfect control and stability on the ground, there is no excuse for allowing your aircraft to wander off the centerline.

The toe operated hydraulic disk brakes are extremely strong and positive and at taxi speeds the aircraft will be brought to a halt in only a few metres.

Finding an area free from any stones or other runway debris it is necessary to warm the engine temperatures up before checking the ignition. I recommend to reach 50°C on the oil gauge before doing the ignition checks. Run the power up to 4000 RPM and quickly switch off and back on each ignition switch, the power drop should be barely noticeable. Immediately after doing the ignition checks reduce the power back to idle. Don't spend a long time at high power settings doing ignition checks because in hot temperatures it may be possible to overheat your engine.

Complete your pre-take-off checks and confirm that the canopy is securely fastened, the seat belts are done up, you have sufficient fuel for the flight and the safety pin has been removed from the ballistic parachute (if fitted).

You are now ready to enter the runway.

Take off

Checking that the runway is clear and no aircraft are on approach make your departure radio calls and taxi to align with the centerline of the runway. Check for any cross wind components and position flaps to 15° (take off setting), if fitted with a variable pitch propeller make sure you are in fine pitch or in the climb setting. Do a last visual check of all instruments and slowly advance to full power keeping the aircraft aligned with the runway, ensuring that the Tacho RPM remains below 5600 rpm and that the engine is performing as it should.

Ground roll on the TL 2000 Sting Carbon aircraft is surprisingly short and once the aircraft reaches an indicated speed of 40 kn slowly pull back on the stick to lift weight of the nose wheel. At around 50 kn the aircraft will actually leave the ground by itself, allow the speed to build to around 60 kn for climb.

Climb

The best climb speed is an extremely steep angle which can limit your vision over the nose, it is my recommendation that passing 100 feet the flaps are retracted to the zero setting and the nose slightly lowered to give a cruise climb between 70 and 80 kn for good visual clearance in all directions. Even at this speed the Sting's climb rate should be around 1000 feet per minute. Keep a check on your temperature gauges and a visual scan for other traffic.

Cruise

Level off and allow the plane to accelerate to cruise speed, if fitted with a variable pitch or constant speed propeller adjust the settings to suit. It will take approximately 60 seconds for the aircraft to come out of its climb configuration and to accelerate into cruise configuration. The TL 2000 Sting Carbon aircraft with its laminar flow wing has a step phenomenon which can be used to great advantage to give the aircraft a high cruising speed.

It is our recommendation to climb slightly higher than your desired cruising altitude and slowly descend back down to the desired level while making any adjustments necessary on the propeller and to trim the aircraft. The aircraft will respond with an increase in speed which can then be maintained for the duration of the flight. It is our recommendation to use this method of getting on the step to get the best performance from your aircraft. If you level off at your desired altitude and try to get on the step using throttle alone it will take a few minutes to actually build up the required speed to stay there, it is much easier to fly higher then descend using gravity and momentum to assist you on to the step.

Descent

Because the TL 2000 Sting Carbon is a fast aircraft your approach to the airport needs to be planned ahead of arrival. Even with the engine running at idle and the aircraft descending at around 500 feet per minute you will still have more than 100 kn on the airspeed indicator. The best method is to actually slow the aircraft ahead of time by reducing power and slightly pulling the nose up to reduce speed, if fitted with a constant speed or in-flight adjustable propeller now is the time to go back to fine pitch. Once you have your speed under control at around 90 kn it is easy to maintain this speed throughout the circuit pattern.

On downwind reduce your power to idle and hold your altitude to allow the airspeed to decay to around 75 kn. Complete your pre-landing checklist and once turned base with an air speed of around 60 kn engage first stage of flap 15°. Using back trim the aircraft can usually be configured with the engine at idle and one stage of flap to descend at around 450 feet per minute with no stick pressure.

The aircraft is extremely controllable in this configuration and it is extremely easy to land, it is our recommendation that only one stage of flap is required for a normal landing. Should you require short field performance it is then possible to use second stage of flap to 30° but it is generally not necessary. As the aircraft nears the ground reduce power completely to idle and hold off in ground effect when the aircraft has settled to around 50 kn, just keep holding off until the aircraft gently touches down on the runway with minimal descent speed.

Landing

The TL 2000 Sting Carbon aircraft is extremely controllable at typical landing speeds and is our recommendation to land on the rear wheels and continue to let the speed decay until gently letting the nose wheel come in contact with the ground at around 35 knots.

You have now completed your flight in the TL 2000 Sting Carbon aircraft, turn off the runway and taxi to the tie down area. Using only idle power will allow the engine enough time to cool down, run through the parking checklist to complete your flight.
