HistorySiemens Halske Sh III 160 -210 / SH.IIIa 240hp hp, 11 cylinder counter rotary. A standard rotary turned cylinders and propeller on a stationary crankshaft, turning in one direction at 1800rpms on a stationary Crankshaft. On these late war types The propeller and the cylinders turned at 900 rpms in one direction, while and the crankshaft turned 900 rpms in the other direction. This counteracted the torque inherent in the standard rotary and produced a maximum of 210hp. Later a modified version, the Sh.IIIa put out a maximum of 240hp. Another company named 'Rhemag' developed the reliable Sh.III(Rh.) These rotaries were to be the first to be equipped with a true form of throttle control instead of a 'blip' switch.
Airframe applicationsAircraft that used the SH.III & IIIa were:
LFG Roland D.IX
LFG Roland D.XVI
Also several of the experimental Fokker V. triplanes.
Kit ContentsThe small white box contains 27 total parts with a couple of spares for the cylinders (13 pcs) 1 crank case and 11 air induction pipes. No instructions present. Check your references. The visual difference between the Siemens Halske Sh.III and IIIa is an overall diameter of 1050mm and 1070mm respectively. So in scale and under a cowling the difference is minimal. After choosing the kit to use for this resin engine. I will begin by thinning the rear edges to the cowling. Next, I added the forward
support frame for the engine. Remember to keep this item level and square with the cowling. This resin item that was purchased through MisterkitUSA and I'm happy with the resin engine. Mount your engine assembly plumb and square with the horizontal and vertical lines of the forward engine support to the fuselage assembly.
