 Later biplane trainers included the de Havilland Tiger Moth in the RAF, RCAF and others and the Stampe SV.4, which saw service postwar in the French and Belgian Air Forces.The Stearman PT-13 was widely used by the USAAF and the US Navy operated the Naval Aircraft Factory N3N.In later civilian use in the US, the Stearman became particularly associated with stunt flying such as wing-walking, and with crop dusting, where its compactness worked well at low levels, where it had to dodge obstacles.
