Martinsyde S.1 (Early Undercarriage)

The Martinsyde Scout (Type S.1) was never built in large numbers, but it is important because it was one of the first armed tractors, with a Lewis gun fixed to the top wing firing forward and slightly upward to avoid the propeller. Starting in late 1914, S.1's were doled out in ones and twos to R.F.C. squadrons in France and they were flown by air combat pioneers like Louis Strange. They served both in France and the Middle East, finally being retired in the latter half of 1915.Two forms of undercarriage were common; the early form with four wheels (to prevent tip over on landing) and the later, more conventional vee undercarriage.

This product comes in 1:144 and 1:285/6mm/1:288 scales.  The 1:285 scale product contains two aeroplanes, each with a detachable, translucent propeller disk rather than propeller blades.  They are joined by disposable links to keep the price down, since single-part models are more affordable.  You can break the links with nail clippers, wire cutters, or similar.

EDIT:  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.
