In his spare time, Heintz began to design and build his own aircraft, which he named the Zenith, anagram of Heintz. After a little more than a year’s work, the two-place low-wing Zenith was rolled out and successfully flown on 22 March 1970 as F-WPZY.
Soon after, detailed blueprints and construction manuals of the aircraft were drawn up and offered to the growing number of interested builders and flyers.

Zenith Aircraft Company is in the exclusive business of designing, developing and manufacturing kit aircraft. The independent, privately-owned company was formed in 1992 in Mexico, Missouri, centrally located in the United States, and is based in leased 20,000+ sq.ft. production facilities at Mexico Memorial Airport. Zenith Aircraft Company has acquired the exclusive rights to manufacture and market Zenair kit aircraft designs from designer Chris Heintz.
An aeronautical engineer, Chris Heintz is a graduate of the E.T.H Institute in Switzerland. After serving in the Air Force, Heintz worked for Aerospatiale on the supersonic Concorde jetliner, and later became chief engineer at Avions Robin (France) where he designed several fully-certified two and four seat all-metal production aircraft.
In his spare time, Heintz began to design and build his own aircraft, which he named the ZENITH, anagram of Heintz. His all-metal homebuilt aircraft incorporated simple construction methods throughout and after a little more than a year’s work, the two-place low-wing Zenith was rolled out and successfully flown in 1969. Soon after, detailed blueprints and construction manuals of the aircraft were drawn up and offered to the growing number of interested builders and flyers.
In 1973, Chris Heintz, his family and the Zenith moved to North America, where Heintz worked for de Havilland (in Toronto) as a stress engineer on the Dash 7 commuter. Chris decided to form his own aircraft company in 1974, and under the name of Zenair Ltd. started to manufacture Zenith kits himself from his two-car garage. Through the company, Heintz has introduced more than twelve successful kit aircraft designs over the years. In 1992, Heintz licensed the kit manufacturing and marketing rights to Zenith Aircraft Company for the STOL CH 701 and the ZODIAC CH 601 designs, and has developed the new STOL CH 801 and the new ZODIAC XL for Zenith Aircraft Company.
While Heintz officially retired in 2003, he is still very active as a designer, engineer and consultant.

PO Box 650, Mexico Memorial Airport, Mexico, MO 65265-0650.
By 1996, Zenair had a production facility in Mexico, Missouri, USA, headed by Sebastion Heintz (son of the designer, Chris Heintz)
Built by Filip Zejda, it is a conversion of the Czech 1.2 TSI CBZB automotive engine suitable for ultralight and light planes. The engine produced 77kW / 105HP and 175Nm torque in 1500 to 4100 the RPM range. To maintain engine weight at Ultralight category the engine used was with an eight valve head. There is also a 16-valve version of the 1.2 TSI.
After tune the Slovak firm M. M. RACING from Bratislava, torque and speed increased up to 144 hp and 170-180Nm torque at 5500RPM. At 3000-4200 RPM torque is around 200Nm. 5500 RPM in flight, is around 2570 RPM on the propeller, with a 2.14 ratio gearbox. The reduction is Gates Polychain Timing Belts and steel pulleys with eccentric tensioning.
For the highest possible performance during a hot summer day requires cooling the compressed air inlet, that entails redesigning the cowling, or adjust the air inlet cooler designed to cool the compressed air and refrigeration division into two areas. One of them is cooling block and head, and the oil, and the other cools the compressed air inlet and a turbocharger, which are also liquid-cooled.
Test flying in a Yetti J- 03 known too as Swift J-03. During the 1.2 TSI conversion motor tests and subsequent flight tests with Yetti J-03 several propellers have been used with different diameters and different pitch. Each propeller behaved much differently, in terms of performance, climbing, vibration damping and noise produced. The final two-blade wooden propeller was designed and made to order by the Czech Republic. Rudolf Wollner company. A prop with a 2000 mm diameter, with Russian profile and pitch of 18 degree and 75 cm blade length.
Due to the construction height of the aircraft, it is not possible to use a propeller with a diameter of larger than 2000 mm. A controllable pitch propeller would take full advantage of the higher torque 210N at lower RPM for increased speed and economy. Nobody in the Czech Republic produced a useful and lightweight in-flight adjustable propeller for 130-150HP.
The weight of the engine installed in the airframe depends on all the components you need but is approximately 98 kg weight.
The engine does have direct injection, turbocharger with intercooler and a simple single ignition circuit. The engine is an easy fit into existing engine mounting points.
Zee Aero (now Wisk), originally under the leadership of Professor Ilan Kroo of Stanford University, developed a proof of concept vehicle with a series of high, vertically-mounted mounted electric propellers. The proof of concept made its first unmanned hover in December 2011, and in February 2014, completed its first transition from hover to forward flight.
Czechoslovakian engineering student Ivo Zdarsky escaped into Austria in a homemade ‘ultralight’ aircraft powered by a 2-cylinder car engine.
In 1984 the plane was confiscated by police but he bribed the police and got it back.
The student, wearing a bright yellow crash helmet, flew the craft only about 100 to 200 yards above the ground for the entire trip. He parked his homemade, 3-wheeled craft with a basket-like seat outside an Austrian Airlines hangar used for DC-9 jets and sat there until airport employees spotted him.
Police said the man took off from the town of Lozorno, about 6 miles inside Czechoslovakia, at 3 a.m. and landed at Vienna’s Schwechat airport about 4:45 a.m., a 25-mile trip. Police said the student told them he had planned his escape for a year, making secret test flights of the ultralight aircraft.
A witness said the student’s plane was powered by a 600-cubic centimeter, 2-cylinder engine and had a fuel tank taken from a Czechoslovak-made Java motorcycle. Ultralights are prohibited in Austria because of noise and environmental regulations.
The 24-year-old Ivo Zdarsky spoke fluent English and asked for political asylum and wanted to emigrate to the United States or Australia, police said.
Zdarsky was able to sell his plane to Checkpoint Charlie German museum that housed escape vehicles. Afterwards he moved to Los Angeles where he started his own company, called Ivoprop, which produced propellers of his own design.
After being denied an exit visa, Zdarsky decided to take matters into his own hands and build his own plane; a hang glider with a 2-cylinder engine. In August of 1984, he set off at 3 a.m. and made his escape to Vienna where he requested political asylum.
Zdarsky was able to sell his plane to a German museum that housed escape vehicles. Afterwards he moved to Los Angeles where he started his own company, called Ivoprop, which produced propellers of his own design. Ivoprop Corporation, founded in 1984 by Ivo Zdarsky, is an American manufacturer of composite propellers for homebuilt and ultralight aircraft, as well as airboats. The company’s headquarters are in Long Beach, California.
Zdarsky started the company after carving his own propeller for a homebuilt ultralight trike that he flew from Cold War Czechoslovakia, over the Iron Curtain to Vienna in 1984. Ivoprop has sold more than 20,000 propellers since then.
The company’s propellers are built from carbon-fiber-reinforced polymer and feature a stainless steel leading edge.
In 1997 Zdarsky decided to move somewhere close to a runway where he could develop his design for an aircraft that could function as both helicopter and airplane. He came across 400 acres in the Utah desert and purchased it for just $99,000.
On the initiative of the Association of Technicians at the Technical Association in Warsaw in the autumn of 1909, Czeslaw Zbierański went to Paris to get acquainted with the aviation technique of the time. On his return, he designed a wooden plane using a pulling propeller engine, while the biplanes at that time had pushing propellers. After the approval of the project by Wheeler Zbierański left for France to buy materials. Having encountered a Voisin airplane with a steel tube construction, he decided to build a hull from the tube.
Stanisław Cywiński became Stanisław Cywiński’s co-worker, who in the spring of 1910 adapted the project to steel construction and elaborated on the design. The hull of the aircraft was built in the summer of 1910, in a shed on the premises of E. Krzemiński’s lamp factory at ul. Solec 103 in Warsaw. After the construction of the hangars of the Warsaw Aircraft Association “Awia” on the Mokotowskie Field, they moved in the early autumn of 1910 to the hangar No. 1. There construction was completed. In the autumn of 1910 Cywiński bought the engine for the plane.
The biplane was rectangular, double-girder, wooden construction panels, supported by steel pipe posts and crossed with wires. Canvas cover. Controls were only on the upper wing. Truss lattice made of steel pipes connected by screws. Tubes stiffened by ash rods. Rear hull triangular section. Trusses framed by wires. With fabric covering
In May 1911, while attempting to fly an improper connection of the wires to the spark ignition caused gasoline to burn and burn part of the airfoil. In the summer the plane was renovated.
On September 25, 1911, the plane was flown by Michał Scipio del Campo, flying 15-20 km, at a height of 50-60 m, within 15 minutes. The engine was too heavy and too weak, so the Gnome engine from the Morane-Borel aircraft belonging to M. Scipio del Campo was mounted.
When the Russian army took over at the beginning of 1912, the plane was evacuated by Russian lieutenant Krachowiecki, fictitiously buying it. Cywinski dismantled the engine, and Zbierański donated the craft to the Union of Students of the Lviv Polytechnic. The plane was transported to Cracow in 1912, where it was exhibited in the Oleander area and then stored for over a year. There at the beginning of the war in 1914, it burned down during the fire of the exhibition buildings.
