THE ROUND-GERMANY FLIGHT
THE MACHINES
Daimler-Motoren-Gesellshaft.
One of the most famous names, not only in German automobile and aviation circles, but in the world, is that of Daimler. The machines taking part in the Round-Germany flight were designed and built by the Sindelnngen works of the Daimler Motor Co., which have been interested in light 'plane construction for some considerable time. Two very interesting types are entered (some in several examples) for the competition, these being the L.20 and L.21. Unfortunately, photographs are available of the former only. We say unfortunately, because the L.21 machines entered are, according to the entries list, to be fitted with two engines each. As each of these Mercedes engines is only rated at 19 h.p., it will be seen that, in spite of being twin-engined machines, the L.21 may fairly be described as a light 'plane. This is of course a very interesting innovation, and it will be curious to see how the twin-engined type compares for reliability with the single engined.
The L.20 may be said to be a development of the L.15 light 'plane which was described in FLIGHT some months ago. A novel feature of the design is that the machine has been so arranged as to be suitable for use both as a light 'plane and a glider. When it is desired to use the L.20 as a glider, an ingenious arrangement enables the wings to be swept back at a considerable angle so as to bring back the c.p. The engine is removed and a nose-cap fitted over the front of the fuselage. With this arrangement the absence of the engine in front is balanced by the backward sweep of the wings and the machine retains its trim fore and aft.
Constructionally, the Daimler L.20 follows orthodox lines. The wing is placed low on the fuselage, and is of the cantilever type. The wings are attached to short wing roots built into the fuselage, and can be easily dismantled for transport, when they fold fiat against the sides of the body. The fuselage is of ordinary girder type and fabric covered. The undercarriage is divided so as' to minimise the risk of the machine tripping up in long grass.
This 'plane has a Mercedes engine specially developed for use on light 'planes. It is of the two-cylinder opposed air-cooled type with a bore of 75 mm. and a stroke of 100 mm., giving a cubic capacity of 885 c.c. The wing area of the L.20 is 20 sq. m. (215 sq. ft.) and the empty weight is 220 kg. (485 lbs.), with a useful load of 170 kg. (375 lbs), the total loaded weight being 390 kg. (860 lbs.). The top speed is stated to be 100 km./h. (62 m.p.h.) and the landing speed 60 km./h. (37 1/2 m.p.h.), the ceiling (which has actually been reached in flight) is 3,500 m. (11,500 ft.).

The tip of the tail plane may just be seen on the right of the picture. The Hohe Tauern mountain chain is seen in 3, while 4 shows the two aviators, Dr. von Langsdorff (left) and Herr Guritzer the pilot, on their return to Sindelfingen.
