Can you imagine? No wright patent, no three axis control. No wright flights. And that is what would really have held aviation back!
Detailed drawings containing all the essential things of the 1902 glider had been published in August 1903 in L'Aerophile, before the Wright brothers finished their 1903 plane.

The 1902 glider of the Wrights was thoroughly tested in France, in 1904, including the Wing Warping (see the picture).

Ailerons were also mounted and tested on the french version of the 1902 glider (see the picture below).

There is also the May 22, 1906 patent that had been already published in Jan. 1906 in L'Aerophile, pag. 21, see:

In the beginning of 1906, a mountain of data regarding the 1902 glider, built by the Wright brothers, had been accumulated and one conclusion was that the roll control should be maintained automatically while the surfaces responsible of pitch and yaw have to be handled by the pilot.
As a general conclusion, despite all efforts and improvements, the 1902 Wright type gliders did not perform well and were abandoned.
