The Farman Jabiru Engine Cooling problems

[Thruster87]

The prototype, a 1923 F-3X Farman Jabiru was a high-wing strut-braced monoplane with a wooden wing, tapered in a curve from 6 metres chord at the root to 3 metres at the sawn-off tips. The fuselage was of mixed metal and wood construction. The nose was like that of the Goliath only deeper and contained two passenger seats. Behind this front cabin was a small section with semi-bulkheads fore and aft. In the top was the open cockpit for one or two crew. The main cabin had six seats. Four 180 hp Hispano Suiza 8Ac water-cooled engines powered the aircraft. They were mounted in tandem pairs at the ends of stub wings. The biggest problem was the cooling of the rear engines. The prototype, F-ESAR originally had cooling surface on the inner struts, but later two Lamblin radiators were mounted above each pair of engines. Still later, a triangular radiator was mounted in front of each engine. Was this name sake the pre-curser to the current jabiru engine cooling issues ?
