Top Flite S.E.5A - Manual (Page 8)

Specific details cannot be given for these pushrods, because as with the radio and
engine, etc., requirements and equipment will differ from one builder to another.
Whichever layout is chosen it will be found that there is ample space inside the
model to carry out any desired positioning. However, we repeat to newcomers that
the advice of an experienced R/C modeler will be invaluable.
23. Break up and discard false former F-12 from the fuselage. Smear a coat
of glue over the planking joint so exposed. Do not attempt to install cabane struts
at this time. For this job we will need the wings, so let's start those.
24. Refer to Figure 8 which shows the first section of the wing to be made—
the lower right-hand panel. Take one of the prejoined 1/4" x 1/4" basswood wing spars
and trim to exact length over the plan. Note that this is the longer rear spar. Slide
one W-3, one W-4 and six W-5 wing ribs in this order loosely onto the spar, push-
ing them toward the center of the spar temporarily. The dihedral brace on the
spar faces forward. Cut two pieces 8-7/8" long from the1/8"x1/4" balsa strip provided,
and glue these on top and underneath this rear spar at its outer end.
3/8" x 1/4" SPAR CAPPING
25. Take one of the pre-joined 3/8" deep basswood spars and cut to exact
length over the plan. This is the shorter forward spar. Spread out the ribs on the
rear spar and feed the forward spar through them from the root end, making sure
dihedral brace faces rear. Slide three W-6 and one W-7 ribs onto the forward spar
in correct order. Slide all ribs back and forth along both spars until they are all
in approximately the correct positions.
26. Place scraps of 3/16" sheet or square balsa shims over the spar positions
on the plan, except at the outer end of the rear spar, where the shims should only
be 1/16" thick. Lay down the wing framework on the plan, with the spars held up
by the shims. As it is not practical to pin through the hardwood spars, hold the
assembly down with a few small weights, making sure it cannot move.
27. Shuffle ribs to exact position over the plan (tweezers are handy for this job)
and lightly spot-glue each rib-to-spar joint. This will hold these joints while the
structure is completed; later on all these joints should be carefully and completely
glued when the wing is lifted off the plan and access is available all around each
joint.
28. Cut a piece of pre-formed L.E. section to correct length and glue in place,
shimming it up to the steps in the ribs with scrap 1/16" balsa. Pin and glue the pre-
formed T.E. to the ribs, shimming up 1/16".
29. Glue two W-11 pieces together for wing tip. While these dry, slip W-8
riblets into place and glue. Trim front of outermost W-6 and glue laminated tip
W-11 in place and complete the tip with short length of 1/4" sq. to rear spar. Glue
in 1/16" x 1/4" stiffener against outermost W-5 rib, then riblets W-9 and W-10. Glue
W-17 in place.
30. Glue in W-12R (ply) bellcrank bearer, noting that it lays at an angle. See
full-size drawing of wing section at this point on the Plan Sheet.
