O.Thetford, P.Gray German Aircraft of the First World War (Putnam)
Sablatnig C I
Built during 1917, the Sablatnig C I was a conventional C type two-seater of wood and fabric construction. At least two aircraft were built, Nos. 7700/17 (illustrated) and 7702/17, which served as prototypes for the subsequent N 1 type. The vee cut-outs in the trailing edge of the lower wings are usual - and unexplained. The lights built into the leading edge of the upper wing should be noted. Six 50 kg. bombs could be carried. Engine, 180 h.p. Argus As III. Span, 160 m. (52 ft. 6 in.). Length, 8.7 m. (28 ft. 6 1/2 in.). Weights: Empty, 1,050 kg. (2,310 lb.). Loaded, 1,540 kg. (3,380 lb.). Speed, 120 km.hr. (75 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 9 min., 2,000 m. (6,560 ft.) in 20 min. Armament, one Parabellum machine-gun.
Sablatnig C II
Built round the 240 h.p. Maybach engine during 1918, the Sablatnig C II remained only an experimental prototype. The wings were braced with two bays of I-struts, and the fuselage and vertical fin were ply-covered. In many respects the machine favoured the SF 7 seaplane, the inboard wing bay being braced in identical manner. Engine, 240 h.p. Maybach Mb IV. Span, 12.5 m. (41 ft. 0 1/4 in.). Length, 8.3 m. (27 ft. 2 3/4 in.). Height, 3.2 m. (10 ft. 6 in.). Weights: Empty, 1,070 kg. (2,354 lb.). Loaded, 1,600 kg. (3,520 lb.). Speed, 150 km.hr. (93.75 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 4.5 min., 5,000 m. (16,400 ft.) in 30 min. Range, 525 km. (328 miles). Armament, one Parabellum and one Spandau machine-guns.
Sablatnig Experimental C Type
These two machines were variants of the C II machine in an obvious endeavour to compare the advantages of the more normal parallel strut arrangement (above) with the I-strut system of the C II. For further comparison the X-strul cellule (below) was tried, this machine also differing in having overhung balanced elevators. Although not confirmed, dimensions were doubtless largely the same as those for the C II. Engine, 245 h.p. Maybach Mb IV.
Sablatnig N I
Built during 1918 to the N specification (which was first devised in August 1917), calling for a single-engined two-seat night bomber, the Sablatnig N I bore more than a passing resemblance to the C I. Probably a short series was constructed, as Serial Nos. 7729/17 and 7730/17 have been noted in addition to 7745/17 (illustrated above). Engine, 220 h.p. Benz Bz IV. Span, 16.0 m. (52 ft. 6 in.). Length, 8.7 m. (28 ft. 6 1/2 in.). Height, 3.2 m. (10 ft. 6 in.). Weights: Empty, 1,190 kg. (2,618 lb.). Loaded, 1,860 kg. (4,092 lb.). Speed, 125 km.hr. (78.125 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 10 min., 4,000 m. (13,120 ft.) in 59 min. Armament, one Parabellum and one Spandau machine-guns.
