Semi-fictional skin based on Bf-109V-14 D-ISLU.
D-ISLU (a Bf-109D prototype) was flown 1937 at a race competition in Duebendorf, Switzerland by Ernst Udet himself. The airplane had to make an emergency landing because of an engine failure. It was equipped with a special DB 601 "Rennmotor" modified for race. Because the Messerschmitt won most of the competitions Switzerland bought 99 Bf-109's from Germany (10 D & 89 E-3a).
Tested with DCS 2.7.9
