16. Enclose the tip spar pocket by laminating the 1/16 in balsa webbing S9 (sheet 04/21) spanning sub rib R4a and
rib R5 as illustrated below. Note: it may be helpful to lightly sand the edges of this part (just enough to remove
the laser burn) then bond with medium CA glue. Attempt to apply glue sparingly to the forward surface of the
S8 plywood pocket to minimize any glue that may squeeze out inside the tip spar pocket and cause fit issues
with the tip spar.
With the S9 webbing installed complete the step by installing sub rib R4b (sheet 02/21) to notches in webbing.
Retain with a drop of CA glue at tab and notch locations.
17. Install 3/32 in. part W6 (07/21) to wing assembly as illustrated below. IMPORTANT to avoid warping the outer
rib R5 it is strongly suggested that you stand the wing on end with R5 completely supported against your FLAT
work surface while bonding W6 to the assembly.
18. Install 1/8 in. balsa parts LE1 (sheet 11/21) to the right and left INSIDE surface of ribs R1. Align parts using the
notches and seat fully against spar.
19.
The carbon wing spars should now be thoroughly bonded to the wing assembly.
Lay the wing assembly
flat on top of your work surface and wick thin CA glue along the entire length of the upper and lower carbon strip
wing spars.
