The aircraft fuselage is made from metal tubing, covered in doped aircraft fabric. The Airdrome Sopwith Pup has a wingspan of 27 ft (8.2 m) and a wing area of 205 sq ft (19.0 m2). It can be equipped with engines ranging from 110 to 150 hp (82 to 112 kW). The standard engine used is the 110 hp (82 kW) four stroke Rotec R2800 radial engine. Building time from the factory-supplied kit is estimated at 450 hours by the manufacturer.[1][2]
