Beagle B.121 Pup

 


 

An aerobatic lightplane, the Pup was built by Beagle Aircraft in England. The Pup was sold in four models: the Pup-100, -150, and -180. The Pup-100 model carries two seats and two optional children’s seats. It's powered by a 100 hp Rolls-Royce/Continental O-200-A four cylinder engine.
 
Production of the Pup-100 began in February 1968. The Pup-150 is quite similar to the Pup-100. The fuselage is only three inches longer while wingspan dimensions of the low-wing tricycle gear airplane remain the same. A 150 hp Lycoming O-320-A2B engine allows optional seating for four. The Pup-150 also offered a larger 34-Imperial-gallon fuel tank as opposed to the standard 24-Imperial-gallon tank installed as standard equipment in the 100 and 150 models. A large rudder on the 150 allows full aerobatics including unlimited spinning. The Pup-160 was powered with a 119kW Lycoming O-320-D2C engine.

A total of 128 Pups had been delivered by the close of 1969, when 267 aircraft were on order. The company went into liquidation and the Pup was developed into the Bulldog by Beagle, then Scottish Aviation.
