5. Now slide ribs
R2, R3, R4
and
R5
the spars of one wing, roughly positioning them.
6. Place the fuselage against the side of the work bench with the rib tabs resting on the
surface over the plans. Some small weights on the spars should hold it while you position the
ribs to location. Align the back edge of each rib tab with the trailing edge of the wing on the
plans. Pin them in place if necessary.
7. Once the ribs are located over the plans, CA them in place on the spars.
8. Locate the 1/4” sq. x 42” balsa trailing edge stick. Notch for aileron horn as shown if you
are using 1 aileron servo, if you are using 2 skip the notch. Carefully slide it through the 1/4" sq.
holes in the fuselage and center it. Now glue it in place on the notch provided at the end of each
rib. Tack it the ends of the ribs, keeping as much glue off the tab possible. The sheeting over
the ribs will hold them in place securely.
9. Locate the four pieces of 3/32" x 1-1/2" x 24", trailing edge sheeting. Apply glue to the ribs
and trailing edge. Install flush with the trailing edge and against the fuselage allowing it to over-
hang the tip.
10. Next find a 3/8” sq x 36 stick. Cut to 24” in length. Glue one into the notches provided in
the ribs along the leading edge. It will be necessary to file the diamond shaped hole in the fuse
to accept the LE.
11. Locate four, 3/32” x 3” x 36" sheets. These will have to be cut to size and shape
before gluing in place. Cut each sheet to 24” in length. Starting at the upper left hand corner,
draw a line at 68 degrees angle, from the end, across the sheet and cut off the corner. Cut three
more sheets to this configuration. Refer to the plans if needed.
12. Locate one of the leading edge sheets on the wing and check the angle with the fuselage. It
should be very close, that is, if you cut the 68 degree angle accurately. Sand slightly if
necessary. Bevel and trial fit the front edge of the sheet to fit snugly against the fuselage and
3/8" sq. leading edge. Apply CA to the beveled edge of the sheet only and glue in place along
the leading edge with the sheet resting on the ribs and against the leading edge. Next, apply CA
to each rib. Bend the sheet down to the ribs and hold until cured.
13. Break off the tabs on the bottom side on all the ribs and install the trailing and leading edge
sheeting on the bottom side. Trim off any rib tab balsa which might have been glued on at the
trailing edge. Take care not to twist the wing and build in a warp. Now install the front spar ply
brace

. Apply glue to the tab and the spar, then slide the brace into the slot in the rib R1
and hold against the spar until the glue is cured.
14. Find the two 3/32" x 3/8" x 24" rib cap strips. Cap rib R3, R4, and R5 on both sides of
the wing. A cap is centered on each rib. Glue them in place carefully.
