The Siemens-Schuckert D.III was a German single-seat fighter built by Siemens-Schuckert Werke. The D.III was a development of the earlier Siemens-Schuckert D.IIc prototype.[1] The D.III was an (nearly) equal-span biplanepowered by a 160 hp (119 kW) Siemens-Halske Sh.III bi-rotary engine. Idflieg placed an order for 20 aircraft in December 1917, followed by a second order of 30 aircraft in February 1918.
Approximately 41 D.IIIs were delivered to frontline units between April and May 1918 Most aircraft were supplied to Jagdgeschwader II,whose pilots were enthusiastic about the new aircraft's handling and rate of climb. After only seven to 10 hours of service, however, the Sh.III engines started showing serious problems with overheating and piston seizure. The problem was later traced to the Voltol mineral oil that was used to replace the now-scarce castor oil. Furthermore, the close-fitting engine cowling provided inadequate cooling to the engine.
In late May 1918, Jagdgeschwader II replaced its D.IIIs with the older Fokker Dr.I. The remaining D.III aircraft were returned to the Siemens-Schuckert factory, where they were retrofitted with new Sh.IIIa engines, an enlarged rudder, and cutaway cowlings that provided improved airflow. A further 30 new production D.IIIs incorporated these modifications. Total production amounted to 80 aircraft.
In July 1918, the D.III returned to active service as an interceptor with home defense squadrons. By this time, the D.III had been replaced in production by the Siemens-Schuckert D.IV.

Product Description
The giant scale Siemens D.III plan set clearly illustrate all structure as well as showing installation of landing gear. The Siemens D.III plan shows the installation of servos and Zenoah GT 80 Gas twin engine and features removable wing panels. The basic structures use conventional “modeling” tools and materials such as balsa and plywood, and the techniques are straightforward; easily accomplished by anyone with previous model building experience. There are many online building threads at www.rcuniverse.com forums and www.rcscalebuilder.com forums for Kerry Sterner's plans. Tech support is also available via email at www.ziroliplans.com or by phone 9:00 to 5:00 Mon - Fri EST 631-467-4765. The plan includes full-size templates for all the required parts allowing you to cut a complete “kit” before you start construction. If you would like to purchase a wood kit see KIT CUTTER'S on selection bar at the top of each page. The plans have instructions notes on the plans. If you choose gear or an engine not shown on the plans you should have them on hand when you start construction to make any changes needed for mounting. Nick Ziroli Plans recommends covering the airframe with Solartex iron on cloth covering(available at Balsa USA) and your favorite paint system. Nick Ziroli Plans has building and scale accessories available for the Siemens D.III
