Typical XLC Flying System

The swing arm from an enclosure below can be pivoted up so that one of the quick-release pins may be inserted through the holes in the rigging slot on the frame and the slot in the swing arm, linking the two enclosures together. The vertical tilt angle of the bottom enclosure is then determined by the hole in which the swing arm is pinned. The XLC-127 and XLC-127+ enclosures may be angled from 0° to 8° in 1° increments, while the XLC-118 enclosure may be angled from 0° to 12° in 1° increments. The angle adjustment holes are detailed in figures 4a and 4b. This pin fixes the maximum distance the back corners of the enclosures may be separated.
