Design and development
Kurt Tank studied electrical engineering, but he also tried his hand at a home-built glider, nicknamed Teufelchen (en:Little devil). Anxious to compete at the Rossitten coastal gliding competition in 1923 Tank had the LFG-Stralsund works complete the glider in time for the competition; transporting the aircraft by horse-drawn cart.[2]
The 'B2' was characterized by warping wing-tips, in the hope of dispensing with ailerons. Construction was mixed with wooden structure covered with aluminium sheeting, which earned the Teufelchen a prize for best construction.[2]
After Tank crashed the B2 it was returned to Berlin and repaired at the Sablatnig works where it had been built. The B2 next attended the 4th Rhön meeting in August 1923, where Tank had a hard landing. The 2nd Rossitten coastal meeting saw many of the competitors flying over the dunes and sea, including the B2, which Möller was forced to land in and the B2 sank.[2]
