Build Instructions
Wing
The wing is composed of two spars (main and
sub), leading edge, trailing edge, ribs and sub
ribs. Wing parts are designated with a “W”
followed by a number. Parts have been
numbered so that the wing assembly and required
parts follows in numeric order from W1 to W17.
The wing is assembled one half at a time and is
composed of a right and left side. Assembly
begins with the left half of the wing and works out
to the wing tip. When a part is required in the
build sequence (for instance “W3”) refer to the
plan set for part placement.
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.
10. Locate and bond together parts W1a and
W1b to create W1 main spar. Locate and
bond together parts W2a and W2b to create
W2 sub spar. Using the plan set as a guide,
dry fit ribs W3 to slots within spars W1 and
W2. Note: The bottoms of ribs should seat
flush with bottom of spars.
11. Locate ribs W4 and W5 in slots in W1 and
W2. Use plan set as a placement guide.
12. Assemble W6 trailing edge over plan set from
parts W6a, W6b. Tack glue parts W6b to
W6a to retain parts within assembly.
13. Fit assembled W6 at trailing edge of ribs W3,
W4, and W5. Tack glue W6 where it contacts
ribs to retain within assembly.
14. Locate leading edge jig W7 at leading edge of
wing, with tabs facing forward, notches facing
aft, and etched arrow on part W7 facing rib
W3. Use plan set as a placement guide. Fit
W7 flush with bottom of ribs W3, W4, and W5
at leading edge. Ensure that W7 is properly
seated to rib assembly and retain using tack
glue method described previously.
15. Fit sub rib W8 spanning W1 main spar and
W7 leading edge jig. Tack glue part at W1
and W2 to retain.
16. Fit sub rib W9 spanning W1 main spar and
W7 leading edge jig. Tack glue part at W1
and W7 to retain.
17. Fit tip rib W10 to assembly spanning sub spar
W2, main spar W1, and leading edge jig W7.
Tack glue W10 to assembly at W7 leading
edge and spar W1. Do not glue W10 to sub
spar W2.
18. Fit notches in W11 leading edge over tabs in
W7 at leading edge of wing. Retain W11 by
tack gluing at each rib and sub rib interface.
19. Assemble W12 wing tip from parts W12a and
W12b. Fit and bond parts over a flat work
surface.
20. Fit W12, wing tip to wing assembly. First,
align tabs in spar W2 and rib W10 with
corresponding notches in W12. Align wing tip
to terminate flush with W6 trailing edge, Now,
bond wing tip at tab and notch locations and
trailing edge.
Next, wrap W12 wing tip forward to leading
edge fitting notch in W12 to corresponding tab
at main spar W1. Align W12 to follow contour
of tip rib W10 and bond from sub spar W2
forward to main spar along tip rib W10.
Finally, complete wing tip by wrapping W12
forward to leading edge following contour of
tip rib W10, nesting tab on W10 within
corresponding notch at W12. Wing tip should
come to rest with the top surface of W12
flush with top of leading edge part W11. Bond
from main spar forward to leading edge and
along leading edge where W12 contacts W11.
21. Hold wing assembly flat against your work
table and fit W13 truss rib where indicated on
plan set. W13 should fit flush with bottom of
wing and taper in width as it approaches the
leading edge.
With W13 installed, and your wing held flat to
your building table, thoroughly bond all parts
within the wing assembly.
22. Repeat steps 11-21 for right side of wing
assembly.
