Dynaflite DYFA2016 - Manual (Page 24)

U 1. Sand all three wing panels with fine-grit
sandpaper to remove glue bumps. Blend all the ribs
to the spars, LE and TE. Smooth all surfaces.
U 2. Use a small 90 degree triangle or square to
draw a 1/8" wide slot centered between the spars
on the #2 ribs on both outer wing panels.
U 6. Test join the wing panels with the dihedral
braces and adjust the slots in the ribs or the length of
the braces so the spars and LE's align and the wing
panels fit together without gaps.
First join the right outer panel to the center panel so
your progress matches the photos.
U 3. Use a sharp #1 1 blade to cut the #2 ribs
along the lines and remove the balsa for the
dihedral brace.
U 4. Mark and cut the slots on the #2 ribs at both
ends of the center wing panel the same way.
Q 5. Remove the die-cut 1/8" plywood dihedral
braces from their die sheets and remove slivers or
die-cutting irregularities with your bar sander.
Position the dihedral braces over the drawing on the
plan and mark the "root" and "tip" ends of the
dihedral braces as shown.
Refer to this photo for joining the wing panels.
U U 1. With the outer panel temporarily joined to
the inner panel, raise the outer panel with a balsa
stick, a stack of balsa sheets or something similar, so
the tip at the last rib is 3/4" above your building
table. Temporarily clamp the panels together with C-
clamps, spring clips or clothespins so you will know
where to put them when you are actually gluing.
Note: If your aileron servo is mounted in the wing at
this time, make sure the cord and connector are not
sticking out of the bottom. The center section must
rest flat on your table while you join the outer panel.
