.

a. Locate the two .270 o. d. x 36" nylon outer push rod tubes (black). Roughen the last 4" on both ends of each outer
tube with sandpaper to aid glue adhesion.
b. Slide the outer push rod tubes forward through the pushrod exit slots in the fuselage sides and the holes in the
formers. Continue sliding the tubes forward as far as you can, they will be cut to length later.
c. Apply CA to the outer tubes at the pushrod exit slots - from both the inside and the outside of the fuselage. With
either glue or glue and filler fill the area around the tube where it exits the fuselage. Now glue the tube to each
former front and rear.
d. Use a single-edge razor blade to rough trim the outer push rod tubing flush with the outside surface of the fuselage.
Sand the pushrods flush with the sides of the fuselage.
36.
Check the fuselage for joints that could use another application of glue. Fill any
gaps at the Tee-Lock tabs and slots with MEDIUM CA. The fuselage should now
be ready for final sanding. With 80 grit sandpaper and a block, sand the tee-lock
tabs flush with the fuselage sides and round the bottom edges of the fuselage
and the corners of the balsa top deck. Switch to 220 or 360 grit for the final
sanding.
Mounting The Wing To The Fuselage
NOTE: You must have a completed wing before proceeding.
37.
a. Careful alignment is particularly important, so take your time and be very
accurate when making alignment marks and taking measurements.
Measure the span of the wing and mark the center of the leading and
trailing edge of the bottom of the wing. I know, you built both wings
identical, but you'd be surprised how often one wing turns out to be just a
'little bit' longer than the other. Measure and mark the center of the
fuselage at the front and rear of the wing saddle.
b. Place the wing on the fuselage and check the fit. If everything was
properly built the wing should fit into the opening without any gaps. If the
wing does not fit properly, now is the time to sand off any bumps or fill any
hollows to match the contour of the wing. DO NOT CHANGE THE
INCIDENCE OF THE WING.
c. Tape the wing to the fuselage and take measurements from the wing tip to
the tail of the fuselage. Both measurements should be the same. If not,
rotate the wing, keeping the leading edge in place, until both
measurements are identical. Remark the trailing edge to reflect the correct
position. Remove the wing from the fuselage.
38.
a. Locate the two 1/4" diameter x 1-3/4" wing dowels and sharpen one end of each to a point, keep the point
symmetrical and centered. Push the dowels into the holes in F-2 so that only the points remain sticking out into the
wing opening. Slide the wing into position, making sure it is centered on and square to the fuselage. When you
remove the wing, there should be two small indentations in the leading edge.
b. Drill 1/8" holes through the leading edge at the indentations. Enlarge the holes to 1/4". Extend the 1/4" hole
completely through the dowel support block. It is important to keep the drill aligned with the wing center line.
c. Remove the wing dowels from F-2. Put a piece of wax paper over the face of F-2 and reinsert the dowels, forcing
them though the wax paper. Push the dowels in only 3/8", leaving most of their length exposed.
d. Trial fit the wing in position, sliding it onto the dowels. Check to see that the wing seats properly on the fuselage. If
not, slowly enlarge the holes in the leading edge of the wing until it does seat properly.
39.
When satisfied with the fit of the wing and wind dowels, coat the inside of the holes in the leading edge with epoxy. Slide
the wing back into position on the dowels. Hold the wing in place until dry, then remove the wing and fill any gaps around
the dowels with another application of glue.
