On August 18, 1903 he flew with his self-made motored gliding airplane 4 months before the first flight of the Wright Brothers
Wright brothers
The Wright brothers, Orville and Wilbur , were two Americans credited with inventing and building the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight, on December 17, 1903...

. He made his first attempts with a plane with three lifting surfaces, but soon switched to two surfaces. They were modelled after the Zanonia
Zanonia
Zanonia is a monotypic genus in the flowering plant family Cucurbitaceae .The only species is Zanonia indica, a medium-sized liana found in the Indian Subcontinent and Southeast Asia east to New Guinea. It has a number of subspecies.-External links:*** * KBD: Kew Bibliographic Databases of Royal...

Fixed-wing aircraft
A fixed-wing aircraft is an aircraft capable of flight using wings that generate lift due to the vehicle's forward airspeed. Fixed-wing aircraft are distinct from rotary-wing aircraft in which wings rotate about a fixed mast and ornithopters in which lift is generated by flapping wings.A powered...

The plane was equipped with a single-cylinder 10 horsepower
Horsepower
Horsepower is the name of several units of measurement of power. The most common definitions equal between 735.5 and 750 watts.Horsepower was originally defined to compare the output of steam engines with the power of draft horses in continuous operation. The unit was widely adopted to measure the...

 (7.5 kW) Buchet engine driving a two-bladed pusher propeller
Propeller
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid is accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's...

 and made hops of up to 200 ft (60 m), flying up to 10 ft (3 m) high. In comparison Orville Wright's first controlled flight four months later was of 36 m (120 ft) in 12 seconds although Wilbur flew 59 seconds and 852 ft later that same day.

He founded a flying school and a plane factory, but did not have much success.
