The Pup's light weight and generous wing area gave it a good rate of climb. Agility was enhanced by having ailerons on both wings. The Pup had half the horsepower and armament of the German Albatros D.III, but was much more manoeuvrable, especially over due to its low wing loading. Ace James McCudden stated that "When it came to manoeuvring, the Sopwith would turn twice to an Albatros' once ... it was a remarkably fine machine for general all-round flying. It was so extremely light and well surfaced that after a little practice one could almost land it on a tennis court." However, the Pup was also longitudinally unstable.
