Engine cooling was via thin surface radiators on each wing.
2.
The engine was cooled instead by a surface radiator wrapped around the top of the bodywork, just in front of the driver.
3.
In Germany, the G�nter brothers developed an alternative design combining evaporative cooling and surface radiators spread all over the aircraft wings, fuselage and even the rudder.
4.
Radical surgery was performed to turn the sesquiplane into a biplane, with strutted wings, wing surface radiators, enlarged tail surfaces and a set of floats also part of the redesign.
5.
The PW-8 ( Curtiss Model 33 ) had been developed from the Boeing MB-3A . Although the PW-8 was faster than the PW-9 ( both having top speeds in excess of 165 mph ), it was otherwise outperformed by the Boeing plane, and its surface radiator cooling system, mounted on the upper and lower surfaces of the top wing for streamlining, was more difficult to maintain and vulnerable in combat.
