WPL USER GUIDE V1.0

WPL USER GUIDE

Ground-stack Bar and Outriggers

This precision alignment bar (fig. 9) is used in conjunction with the touring flying frame to define the angle between the WPL array and the 
flying frame when the system is configured for ground stacking. Depending on where the ground-stack bar is attached to the touring flying 
frame, a range of aiming angles from +4° to -10° can be achieved.

Outrigger brackets (fig. 10) are used in conjunction with the flying frame and ground stack bar for ground stacked system applications. 
These attach to the front of the flying frame to improve stability.
