The Hastings was powered by an arrangement of four wing-mounted Bristol Hercules 101 sleeve valve radial engines. These engines were installed upon the leading edge of the wing via interchangeable power-eggs; the air intakes and thermostatically-controlled oil coolers were also present within the wing. A Vokes-build automated air cleaner was present upon each engine, typically deploying during landings and take-offs. Fire detection systems were also installed to alert the crew to such dangers, while fire extinguishers were also installed around each engine. The engines drove de Havilland-built hydromatic four-blade propellers, which could be individually feathered if required.
