Sablatnig C III
  Although no data on this interesting machine is available, it appears to have been based on the same ply-covered fuselage and tail surfaces as the C II. The low wing was of parallel chord and fitted with overhung, balanced ailerons. It was cable braced to the top of the fuselage, and underneath the cables were anchored to an additional pylon incorporated in the undercarriage chassis. A large lifting surface, as in the Fokker D VII, faired in the axle and spreaders. Engine, 245 h.p. Maybach Mb IV (probably).

Sablatnig N.I & Related Types
  
<...>
  The final known Sablatnig two-seater was the handsome, innovative C.III monoplane. The C.III tail and semi-monocoque plywood fuselage were derived from the C.II. Apparently the same 240-260 hp Maybach Mb.IVa engine fitted to the C.II was used, but this time a frontal radiator was employed for reduced drag. The wire-braced monoplane wing was of constant chord, and both ailerons and elevators were horn-balanced. Flying surfaces were covered in lozenge camouflage fabric. The under¬carriage spreader bar was faired into a lifting surface in the manner of later Fokker designs. The C.III was well-streamlined and looked as advanced as any contemporary. Unfortunately, further details and performance of this elegant aircraft are not available, and it remained a prototype.
  The Sablatnig C.II derived from the N.I was a mediocre design deserving of its obscurity. However, the elegant C.III was a real design break-through, although the wire wing bracing appears vulnerable to combat damage and might have been replaced with stronger struts had development continued. The C.III appeared to have good development potential but arrived too late.

This view of the Sablatnig C.III monoplane shows the horn balances on ailerons and elevator and the camouflage fabric covering the wings and tail surfaces. The wings have a constant chord with cut-outs at the wing roots to enhance the observer's downward visibility. Unfortunately, nothing is known of its performance or handling qualities. On the original print metal framing can be seen on the outboard leading edges of both horizontal stabilizers that, if covered, would fair them into the elevators.

This rear quarter view of the Sablatnig C.III monoplane illustrates the excellent field of fire for the gunner. The semi-monocoque plywood fuselage was well streamlined. Two handholds are visible on the lower aft fuselage for ground handling. The under-carriage spreader bar was enclosed in an airfoil like later Fokker designs. Power was the same 240-260 hp Maybach Mb.lVa engine used in the Sablatnig C.II.

This interesting photo shows the Sablatnig C.III monoplane on the left, one of the C.II biplane prototypes in the middle, and a production N.I on the right, making for an interesting picture of Sablatnig design evolution. Although the C.II is smaller and more compact than the N.I, it retains most of its design features other than the strut configuration. On the other hand, the C.III is a major advance. Although the C.III retains the basic fuselage and tail design of the earlier types, its low-wing monoplane design had much less drag; its frontal radiator also reduced drag.
