The 25 hp engine had to be adapted by Vuia as a suitable engine was not available. He found a place, near Paris, where he could test his airplane, and on March 18, 1906, the Vuia I lifted off briefly. After accelerating for about 50 m, the aircraft left the ground and traveled through the air at a height of about 1 m for a distance of about 12 m, but then the engine cut out and it came down. Caught by the wind it was damaged against a tree. On August 9, a longer hop of 24 m at a height of about 2.5 m was achieved, ending in a heavy landing that damaged the propeller.
