MZAS Savage (Zlin)

The Savage is a single-engine, high-wing, two-seater tandem microlight aircraft of classic design. It is built in the Czech Republic in full compliance with the aeronautical regulations in force in that country.

Fuselage
Consists of a reticular structure made up of TIG-welded 4130 aeronautical steel tubing. Access to the cockpit is gained via a single canopy on the right hand side of the fuselage which opens upwards. The fully adjustable seating frame, ample space for the pilots, good all-round visibility and ergonomic controls make flying comfortable and safe even over long distances. Type-approved 4-point seat belts increase the overall sensation of safety provided by the aircraft. The flame-screen section is made of stainless steel to provide optimum protection against fire. The rest of the fuselage is fully covered with a 90-120 g aeronautical skin which is treated and painted. All welds are checked with the aid of penetrative liquids and the tubes are protected against corrosion from their interior too (optional).
Windshield and windows are made of Lexan F 5006. The Savage features a complete set of dual controls
except for the flaps lever. There is also a roomy storage compartment behind the passenger seat.

Wings
The wings are of the rectangular type with rounded extremities: the profile is a modified 4412. The structure is made up of two tubular spars in aeronautical aluminium alloy (doubled on the inside where necessary) and a classically designed system of compressors and diagonals. The ribbing consists of 11 ribs attached to the structure and sewn to the fabric skin. Each wing root houses a welded aluminium tank containing 34 litres of fuel; in-tank fuel level is visible to both pilots. The wing is covered with aeronautical 90 g treated fabric skin. The flaps can be set to 3 different positions with a maximum excursion of 35 degrees. There are two strong aluminium uprights and a universal joint which allows the wings to be folded back for on-road transport purposes.
The employed alloys are of the 2024-6061/t6 type. All nuts and bolts are of aeronautical quality. All the engineering documentation concerning the load tests and studies carried out by aeronautical engineers Franchini and Vizzini (who previously worked at Aeritalia and then Boeing in Seattle) with the aid of sophisticated programs such as the French Catia (aerospace) and the American Nastran is available on request.

Tail
The tail is cruciform and consists of welded tubing covered with a fabric skin. The rudder is connected to the rear swivel wheel for taxiing manoeuvres. The horizontal tailplane is equipped with mechanical trim and can be folded upwards. Ample surface area of the controls provides extremely sure control, especially useful when flying at low speeds (situation in which the Savage performs best), floats fliyng or with crosswinds.


Undercarriage

The undercarriage has the classic rear-wheel tricycle or "taildragger" arrangement. The front wheels are fitted with independent pedal-controlled hydraulic brakes. The suspension is of aeronautical-standard elastic design with a steel safety cable to prevent over-extension. The tail wheel is equipped with a release mechanism which allows it to swivel freely when better on-ground tail control is required. Two large tundra-type low-pressure tyres can be fitted to allow problem-free taxiing over rough airfields (optional).

Controls
As already stated, this aircraft features dual controls, with rigid rod control of the elevator and steel cable control of rudder and ailerons. The mechanical trim is also cable-controlled. The rear stick is also demountable, for safety flights with passengers.

 

 

Engine
The standard engine is a two-stroke Rotax 582 dcdi. Optimum aircraft performance, however, is obtained with a 4-stroke 80HP Rotax 912 UL. For certain types of flying (floats fliyng and mountain flying) the more powerful 100 HP Rotax 912 can be installed. It is also possible to install any other engine with a compatible weight factor (see cg.).

Standard version
The standard aircraft is with the following: Rotax 912 ul, wooden twin-blade propeller, standard yellow colour, anemometer, altimeter, compass, slip indicator, RPM counter, hour counter, head temp. gauge, oil temp. gauge, oil press. gauge, hydraulic brakes, standard tyres, standard upholstery, dual controls, foldable wings, 4-point seat belts, storage compartment. The aircraft can also be fitted with numerous optionals to be decided on at the time of order
