The origins of the Dornier X can be traced back to 1910 when an aircraft first took off from lake waters. By 1911 a series of seaplanes
were being developed in the United States. A few even saw military service during World War I.
As early as 1913, seaplanes began competiting in air races. Designers of airlines, such as the Dornier X, witnessed the development of seaplanes, and believed in their future potential. It was 1919 when a flying boat first crossed the Atlantic, with stops along the way.
Dornier wanted to capitalize on the potential of airliners carrying many passengers over long distances. Although the Dornier X, due
primarily to its lack of power, was not an overall success, it did lay the groundwork for future, more successful, flying boats.
The Dornier X was a German flying boat airliner. It was build for luxury with three decks, and could seat up to 100 plus a crew of 10. There were quarters for sleeping, a bar, and a smoking lounge on the aircraft.
The Dornier X was capable of flying over 1,000 miles. It was the heaviest aircraft to fly while it operated.
At the time of its first flight in 1929, it was also the largest airplane to be built.
The Dornier X flying boat was a seaplane with the hull of a boat. This allowed it to operate from water. However, unlike amphibian
aircraft, it had no landing gear. This kept it from flying from runways.
When the Dornier X first flew, its size would have made it difficult to find runways long enough and large enough on which to
land. The large amount of open waterways at the time made flying boats such as the Dornier X a logical choice.
The aircraft was under-powered and difficult to maintain. The Dornier X was used for passenger service by Lufthansa through 1936
and later exhibited in a museum. It was lost during a 1943 bombing raid.
Two other aircraft, based on the Dornier X, were built. They were purchased by Italy, with one launched in 1931,and the second in 1932.
They were used by the Italian Air Force, primarily for exhibits and as VIP transports. It appears that they were also lost during the war.
The Dornier X that Michael Brauer built from blueprints has a 192" wingspan and 156" length. It is made from balsa and plywood. A total of twelve OS 62 engines power the airplane that weighs 132 lbs.
That's Laddie Mikulasko pictured just above with his 80" wingspan Dornier X. It is powered by twelve Speed 500 type motors. Weight is about 10 lbs.
Mario Schauermann's Dornier X has a 78" wingspan and is powered by Speed 400 motors. It weighs around 11 lbs.
Don Srull built his Dornier X as an electric powered free flight model in 1989. He converted it to radio control and it is still flying today. It has
a 42" wingspan and is powered by Speed 400 type motors. You can find it at AMA Plans under no. 32094.
Not pictured is the Dornier X by Juraj Tinka. It has a 138" wingspan and uses Speed 500 motor power. Weight is about 24 lbs.
Jurgen Schmid's Dornier X has a 96" wingspan with power by a dozen Speed 400 motors. It weighs around 15 1/2 lbs.
