31. Remove wing from plan Slide four W-14 ribs over projecting ends of wing,
spars, getting them in approximately correct position in the wing center panel As
with the panel just made, weight down the spars with 3/16" shim under them
Slide ribs to exact position and glue See Figure 9 and 10. Glue in W-13 and
1/2" x 3/4" x 4" bass block Glue on L. E, the balsa block T. E Pieces and cap spars
with 1/16" x 1/4" to support the center 1/16" sheeting, which is now glued in place.
Don't forget to bevel one edge where the sheet sticks to the L E
32. Tilt the whole wing so the projecting spar-ends are now flat to the plan
and construct the left hand panel in the same way as the right Remember that ribs
W-3, 4 and 5 must be threaded onto the spars before the 1/8" x 1/4" rear spar capping
is glued on
33. At this point turn the wing upside down and attach the formed rear landing
gear wire strut onto the hardwood block in the center panel, using the metal clips
provided Make sure you stay clear of the hole positions in this lower block.
34. Again, cap the spars with 1/8" x 1/4" and sheet the whole underside with 1/16"
balsa
35. Refer to Plan Sheet I and study the full-size view of the lower wing center
section Fasten formed front landing gear wire strut to F-9 with metal clips
Glue F-22's onto wing Glue two F-9A's together, and set aside to dry. Glue F-9 to
F-22's. Then sheet in lower edge with parts F-19, F-20 and F-21.
36. Bring up the lower wing to the fuselage Trim or adjust parts if necessary
Aim for a perfect fit When this is achieved, take off wing, check that the laminated
F-9A's fit well into the hole in F-8. Sand if necessary When satisfied, glue F-9A
on the front of F-9, immediately putting lower wing in position on fuselage so that
F-9A will be in exactly the right position When glueing F-9A on, do not use too
much glue, else some may ooze out of the side and glue up the whole assembly
when the wing is positioned
37. While these parts are drying, slip two solder-tabs on each front LG leg,
then solder the landing gear plates to the legs Use acid flux here, as a strong
joint is essential'
38. After carefully marking the positions of the holes for the nylon wing mount-
ing screws on the underside of the wing center panel, drill right through wing and
the block in the fuselage at one time Use a No 29 ( . 1 3 6 " ) drill Remove the wing
R e d r i l l the holes through the wing with a No 19 or No 18 ( . 1 6 6 " - . 1 7 0 " ) drill
to clear nylon screw Tap the No 29 holes in the fuselage block with a 8-32 tap
Trim away F-19 to allow the heads of the nylon screws to seat right down against
the wing block When the model is finished, these recessed screw heads will be
barely discernable, and will not spoil scale appearance
Try screwing the wing into place See that all fits are perfect, trimming away or
adding if necessary
39. Slide the tabs on the front LG leg to the top of the leg, then glue all balsa
pieces LG-1 to LG-6 to landing gear legs, clamp up securely and set aside to dry
thoroughly Give these parts at least two hours—overnight if possible, before sand-
ing down
When the legs are sanded down, bind them with the 1/2" tape supplied, wrapping
the tape tightly in spiral formation Rub glue into the tape This tape will strengthen
the landing gear and add to the scale effect
