Unlatch, and lower the forward belly pan and verify whether or not their are
slots in the forward corners of the belly pan (approx. 4 x 1 inches each).
Also, check to see if there is a hole near the rear of the left side (approx. 2 inches in diameter).
If “Yes,” continue with step 03, if “No” continue with step 02.
Note: Tyler’s Astar BELLYPAN, if used, may require adjusting the latches for proper fit.
Also see page 3 for specifics on the BELLYPAN.

additional instructions on the template...

shown). However, this modification may also be done to the right side of the
BELLYPAN (if necessary).

original six (6) bolts, on the blue “factory” bottom plate.
Position the AIRFRAME TAB so it points inward (toward the center of the ship).
