In the autumn of 1924 the L15 was fitted with floats and took off from water successfully, at first carrying only the pilot and then with a passenger. Takeoff took 12 seconds in both cases, even with 12.5 hp. Early in these tests a new engine, an uncowled

The flights with the low-powered Harley-Davidson engine attracted attention and launched Klemm on a path which led him, after designing at least two more
Daimler light aircraft, to set up his own light aircraft company in 1926. In 1924 the L15 was finally refitted with its motorcycle engine and was

Daimler management. The engine was demounted and replaced with a long, smooth nose, deliberately designed to be easily removable so that the engine could be

During tests, the powered L15 reached an altitude of 2,150 m (7,050 ft) with only the pilot on board and 1,100 m (3,610 ft) with a passenger; a solo flight lasting 185 minutes was made and one passenger-carrying flight lasted 122 minutes. Other flights covered 190 km
