These would run through August 9, 1938 (L16-L30). Section C rockets included light tank construction, movable-tailpiece (i.e. gimbal) steering, catapult launching, and further development of liquid nitrogen tank pressure method. Lengths varied from 17 ft 4.25 in. to 18 ft 5.75 in.; diameter 9 in., weight empty varied from 80 to 1091b; loaded weight about 170 lb or more; lift of static tests varied from 228 lb to 477 lb; jet velocities from 3960 to 5340 ft/sec. These tests indicated extremely high temperatures for the jet: pebbles of the cement gas deflector were fused and thrown out, starting fires more than 50 ft from the tower. References: 482 .
