...but controlled flight? No.
From the Wikipedia article linked in the summary, it seems like one of his runs promptly crashed into a building with the steam engine powering the craft badly scalding Gustav himself. This pretty much ended his experimental flights, as whatever method that was devised to control his aircraft was obviously insufficient.
The Wright flyer on the other hand had full control (pitch, yaw, and roll) as far as modern flight is concerned. It could do figure 8 turns and could go back around to land where it started. Quite important, since being able to land has more to do with having a safe flight than anything else.
The first Wright flyer was a joke. Didn't have enough power to lift off the ground; didn't even have wheels, just skids. It was only controllable in a very limited way. They didn't fly figure eights for another couple of years. They were also secretive, didn't share their ideas, and in fact refused to give demonstrations to prospective buyers without a deposit. People back in Cleveland did see some of their experimental flights between Kittyhawk and later public demonstrations, but not many; they were pretty secretive.
And the Wright brothers had almost no impact on aviation after that first flight. They preferred to sit on their heels and wait for the world to come to them. Everyone else was out experimenting in public and advancing the state of aircraft design. They were one hit wonders and contributed almost nothing beyond that first flight, and a famous demonstration in Paris in 1908 (maybe 1906). After that, nothing. What they are secondly famous for is their patent battles with the world, which were only settled by the US government strong arming everybody into sharing patents because they wanted to buy military aircraft for WW I in 1917.
The Wright Bros, along with James Watt, are great examples of the counter productive nature of patents.
