[9] The main undercarriage consisted of divided units, each of which carried dual wheels, and the tail was supported by a pair of tailwheels.

[2] The wings were completely redesigned to incorporate heavier spars and a new rib section and gained two extra bays, to provide a greater span.

[2] Siemens-Schuckert delivered the R.VII to the Riesenflugzeugersatzabteilung (Rea — "giant aircraft support unit") at Döberitz on 20 November 1916, and test flights commenced on 15 January 1917.

These serials were changed on 13 July 1915 to G.33/15 - G.38/15, for unknown reasons and again on 6 November 1915 to R.2/15 - R.7/15 in the R (Riesenflugzeug - giant aircraft) series, adopting the R.II to R.VII designations.

[7] The R.VII remained in Vilna, transferred to the Riesenflugzeug Schulabteilung ("giant aircraft training unit"), with which it was still in service in early 1918.
