Remove the panel and apply a small
amount of 5 min epoxy to the carbon tube
(held at 3/4" position) and junctions of #2
rib and balsa/ply spar through holes in #1
rib. A 2" long piece of 3/4" masking tape
will assist here.
NOTE: The following step can use an extra set of hands to hold the fuse.
Install wing panel onto the tubes, holding the carbon tube as long as possible. Pull tape
when close to boom then slide carbon tube fully against boom and then smoothly push
panel fully against boom.
Allow the epoxy to cure, then pull the wing.
The 1/16" ply spar doubler has a dot that
identifies the top. Apply SLO-ZAP to the fwd
side and insert through opening in the root rib
and glue it to the aft side of the balsa spar.
Open a hole in the balsa spar roughlyclose to
the size of hole in 1/16" ply doubler. This
allows access to glue the carbon tube to the
2nd rib. Start the hole with a long 1/4" drill,
enlarge to match opening in ply doubler with
Perma-Grit tool R202C.
Apply Aeropoxy to the intersection of the carbon tube #1 rib, spar, and #2 rib, and 1/16"
ply doubler.
❑ Drill (#43 - .089") and 4-40 tap a hole in
the center of the (1/2" face) 3/8'x1/ 2"x1"
maple block using the CF tongue as a
guide. 4-40x1" SHCS retain tongue - at
both ends. Countersink hole on bottom of
block to aid bolt insertion.
