9. To stack additional IS7s, position the IS7 above
the stack already completed. Swing the rear
rigging links (fig. 1) still affixed to the IS7 (hole
X) until the appropriate holes line up to achieve
the desired rigging position. Refer to the rigging
legend displayed on each IS7 rear rigging piece
(fig. 2). The rigging positions listed on the legend
refer to the rigging position corresponding to the
design in Blueprint. Make sure that both left and
right rear rigging positions are set to the identical
angle.
10. For additional IS7s, repeat step 9.
