The Bü 133 was a development of the Bücker Bü 131 Jungmann two-seat basic trainer. First flown in 1935 (by Luise Hoffmann, the first female works pilot in Germany),[1] it was slightly smaller than the Bü 131. The prototype, D-EVEO, was powered by a 140 hp (104 kW) Hirth HM506 inverted, air-cooled inline-6 engine.[1]
The aircraft showed "astonishing agility" at its first public appearance, the 1936 International Aerobatic Championship at Rangsdorf,[1] but the Bü 133A garnered no orders; only two Bü 133Bs, with 160 hp (119 kW) version of that same Hirth HM506 inline-6 engine, were built.[1]
The main production type was the 160 hp (119 kW) Siemens-Bramo Sh 14A radial powered Bü 133C, which had a distinctive cowling and a 13 cm (5.1 in)-shorter fuselage,[1] and the same fine aerobatic performance as the Bü 133A.[1]
Fifty-two were manufactured under licence by Dornier for the Swiss Air Force[1] (which kept it in service until 1968).[1] A similar number were built for the Spanish Air Force by CASA, and were designated the CASA 1-133.
Today we show you just how awesome a classic model can be with a little love and attention.
the airplane has great performance on 6s 5000 Mah batteries.
