Bactrian deer have, like Yarkand deer, short tails similar to the short tails of wapitis. A total of 68 Wapitis were converted to Wallace Mk I standard. He returned to RAF Hinaidi and joined A Flight No. 55 Squadron flying Westland Wapitis. It replaced its Wapitis with Hawker Harts in February 1932, operations continuing as before. However, initially, the squadron operated Westland Wapitis until it could be armed with the Vultees. In Britain, Wapitis served with the Auxiliary Air Force from 1929 to 1937.
