Wing
Wing parts are designated with a “W” followed by a numeric. Parts have been
numbered so that the fuselage assembly and required parts follows in numeric order
from W1 to W15.
The wing is of traditional spar and rib construction. Many of the parts will have arrows
or
TOP
and
BOTTOM
designations. Unless otherwise specified, part should be
installed with the etched arrows pointing toward the front of the assembly and any
TOP
or
BOTTOM
designations followed.
You will dry fit the majority of this wing assembly together, only gluing at the final
instructional steps. When parts cannot easily be retained with friction, use a single tiny
drop of medium CA glue applied sparingly through a CA glue applicator tip to “tack glue”
the part in place. Should you commit an error in assembly it will be easier to recover
from the mistake and remove or correct the part fit in error if you do not slather the
assembly in glue after each step! Further, this method of assembly will allow our
interlocking design to do it’s job as each successive part installed within the wing will
help pull the entire structure square and true.
8.
Locate the center rib W1.
DO NOT remove the center section knock-out
marked “Remove” from W1 until instructed to do so in step 26.
This
knock-out will remain in W1 through the bulk of the assembly to support the
W1 rib and wing center section.
9.
Fit and tack glue the trailing edge gussets W2 to the rear end of rib W1.
10. Assemble and bond the trailing edge from one part W3a and two parts W3b.
11. Fit and tack glue the trailing edge W3 to the center rib W1 and the gussets
W2.
12. Fit rib W4 to the notch in the trailing edge to the
LEFT
of rib W1.
13. Fit
LOWER
spar W5 to the notches under the forward portion of ribs W1 and
W4. Ensure that rib W1 fits in the CENTER notch in W5.
14. Turn the wing up-side-down on the table. Fit ply part W6 to the recess in
W1 and the slot in W4. The arrow on W6 will point toward the front of the
ribs.
15. Turn the wing back over and fit rib W7 to W6 and the slots in the spar and
trailing edge to the
RIGHT
of the center rib W1.
