The Curtiss HS flying boats were operated with great success by the US Navy during WWI, starting with the HS-1L. They were powered by the 330hp Navy Liberty engine (providing the "L" in the name). HS-1Ls operated out of several bases in France as well as seeing extensive use in the States.
In order to increase the bomb load, the six-foot panels were added to each wing, the rudder was enlarged, and minor changes were made, creating the
HS-2L. The HS-2L was deployed near the end of the war and it is not known whether it saw service, but it saw extensive use after the war. Most HS-1Ls were eventually converted to HS-2Ls.
This model comes in both 1:144, 1:200, and 1:285 (1:288) scales. On the 1:285 product, a propeller disk is used instead of propeller blades (which are difficult to print at small scales). By customer request, the 1:200 product includes no crew.
DESIGNER NOTE:
Models at scales smaller than 1:144 may no longer be available. Shapeways discontinued the material for which they were designed, and the newer materials require that each and every model be adjusted to thicken surfaces like wings. If you are interested in a particular model in a small scale, please let me know and I will prioritize it higher in the queue.
