Bücker Bü 133 Jungmeister (Young master).
This is a single-engine, single-seat biplane of wood and tubular steel construction, covered in fabric. It is a tiny airplane, even by biplane standards - it's not a great deal bigger than a Pitts S2 and considerably smaller than a Tiger Moth.
Introduced in 1935 by Carl Bücker as a single-seat version of the Bü 131 A Jungmann, which was a two-place advanced aerobatic trainer. The Jungmeister became a favorite of European flying clubs...
