A gimbal assembly (150) comprises a body (152), comprising at least one pivot boss (160) projecting radially outwards along a first pivot axis (V) from an outer surface of the body (152); a gimbal (154), comprising an outer case (156) surrounding the body (152) and at least one hole (157) projecting radially outwards along a second pivot axis (H) to receive a pivot pin to pivotally couple the gimbal (154) to a fixed structure. The second pivot axis (H) is perpendicular to the first pivot axis (V) and the outer case (156) is formed at least partially from carbon fibre-reinforced polymer matrix composite material. The outer case (156) comprises at least one cavity (162) on its inner surface in which the at least one pivot boss (160) is located to pivotally couple the gimbal (154) to the body (152), such that the body (152) can pivot relative to the gimbal (154) about the first pivot axis (V) and the gimbal assembly (150) can pivot relative to the fixed structure about the second pivot axis (H).
