The Siemens-Schuckert E.I
was a mid-wing monoplane similar to the Fokker monoplanes but with a better streamlined fuselage, stronger undercarriage, and the counter-rotating Siemens-Halske geared rotary. Though the prototype had flown in autumn 1915, it wasn't until autumn of 1916 that the SSW E.I was active on the front lines, and by then there were better choices available in the Halberstadt and Albatros biplanes.
This product comes in two scales: 1:144 and 1:285/6mm/1:288. The 1:285 product contains two aeroplanes
connected by sprues. You will have to separate the planes from the sprues using wirecutters, fingernail clippers, or similar and file down the joining surface. (Without sprues, the planes would cost significantly more.) At 1:285, propeller disks are included with each plane; you can break them off if you prefer a model without one.
