Composite construction

The Sting is of conventional low wing monoplane design. The spar and wing skins are made entirely from carbon fibre. The surface finish is superb as can be seen from the photo. The airframe is also very strong and is stressed to +6/-4g.

Flaps

The Sting has large very effective split flaps running along 80% of the trailing edge. The flaps have two positions 15° for take-off and 30° for landing. This picture clearly shows the flaps set on landing.

Trim system

The Sting has a large trim tab mounted centrally on the elevator and is operated by a lever in the cockpit.

Undercarriage

The Sting has a robust tricycle undercarriage, which is more than strong enough to operate out of typical grass airstrips. All the wheels are faired as standard.

The main legs are made from composite lay-ups and are separately attached to the fuselage. Wheel dimensions are 500x5. The noseleg is attached to the firewall and has a unique combination of oil and moulded spring damping. Like the main wheels it has a 500x5 tyre. Steering is accomplished through the nosewheel using the rudder pedals.

Brakes

The brakes are independent toe-operated hydraulic disc brakes. Toe brakes may be fitted to both sets of pedals as an option.

Engine

The Sting uses the ubiquitous Rotax 912ULS 100hp engine made by Bombardier in Austria. This engine has a displacement of 1200cc and runs through a 2.17:1 gearbox allowing larger more efficient propellers to be used. The cylinder heads are water-cooled making the engine less susceptible to sudden changes in temperature.

Propeller

The standard propeller for the Sting is the in-flight adjustable Woodcomp SR 3000 3-bladed propeller. This prop is also made in the Czech Republic. The blades are made from wood/composite sandwich.

Exhaust system

There is a custom designed stainless steel silencer supplied with the kit which provides for whisper quiet operation so essential for today's noise sensitive airfields.

Seats

The Sting cockpit is very roomy and has excellent ergonomics. The seats are padded with foam and have full four point Schroth harnesses.

Ventilation

The Sting has circular air vents at the front and sides of the glass cockpit which provide a plentiful supply of cooling air. The Sting can be taxied with the cockpit open allowing plenty of fresh air on a hot summer's day.

The Sting is available with both a glass cockpit or more conventional dial instruments.

The wings are easily removable for storage or maintenance. The procedure requires three people and takes about 25 minutes. The photos show the wing root and the spar being inserted in the D-box.
