U LJ 2. Remove the clamps and separate the panels.
Lay a piece of wax paper on your building table. Mix
a batch of 30-minute epoxy. Coat the joining surfaces
with 30-minute epoxy. Join the inner wing panels with
the dihedral brace. Refrain from using excess epoxy
so the shear webs will fit later. Place the wing on your
building table. Immediately proceed to the next step.
o o 3. Place a weight on the center section to hold it
down. Prop up the outer panel so the tip is 3/4"
above your table. Clamp the wing halves together
the same as you did in the first step.
Q Q 4. Wipe away excess epoxy before it cures. Do
not disturb the wing until the epoxy is fully cured.
Q 5. Return to step 1 and join the left panel to the
center section the same way.
U 3. Make sure the holes in the joining #2 ribs of
both wing panels align so you can route the outer
aileron cable guide tube. If the holes do not align,
open them up with a hobby knife.
Note: These instructions are written for connecting
the ailerons with Great Planes* Flexible Cable
Pushrods, though Sullivan
Gold-N-Push Rods are shown on the plan. If you
decide to use the Sullivan Gold-N-Rods, the
instructions are the same for installing the guide
tubes, but connect the clevises and ball links as
shown on the plan.
U LJ 1. Roughen the outside of a Great Planes 36"
Flexible Cable Pushrod guide tube (not included,
GPMQ3702) with coarse sandpaper so the glue will
stick. Route the guide tube through the holes in the
ribs of the right wing panel.
U U 2. Use a #11 blade to cut an approximately
1/2" diameter circular notch in rib #1 where the
guide tube passes. This will allow the solder
connector to clear the rib without interfering. See the
photo at step 5.
U 1. Use epoxy to glue the four shear webs you cut
earlier to the plywood dihedral braces and spars on
both sides of the joining wing panels. It does not
matter whether you glue the shear webs to the front
or back of the shear webs, but do it the same way
on all four webs for symmetry.
Q 2. Sand-off glue bumps and blend the spars and
LE's and TE's of the joining wing panels.
1-11- 3. Cut a 1/2" long slot in the sheeting
between ribs #6 and #7 where the guide tube will
pass through. Be careful not to make the slot too far
aft or the clevis will interfere with the guide tube and
limit aileron throw. The aft end of the slot should be
approximately 1-1/4" from the aft edge of the aft
spar. Route the guide tube through the slot and cut
the tube so it protrudes from the sheeting (on top of
the wing) about 3/8".
