locate Fl with the engine crankshaft, with the spinner backplate mounted on the engine, and glue
in place.
20. Now round off the nose to Fl. So that you don't round off too far back it is a good idea to
lay rib Rl in position and trace around it with a ball point pen. This will give you an idea where
the wing leading edge starts. Provide room for the muffler and needle valve after rounding off
and shaping.
21. Locate, drill, and install the front hatch retaining dowels as well as the aft hatch block in the
fuselage. Cut these from the 1/8" dowel provided. Drill a 1/8” hole through the fuse sides and
into the hatch plates (HP) for the ½” 4-40 blind nut and bolt. Re-inforce the holes in the balsa
fuse sides with ca.
WING CONSTRUCTION
In order to ensure a straight wing with no warps, build the wing panels the following way. The
wing spars are installed in the fuselage, the ribs slid in place and then the sheeting and cap strips
applied. Began by taping the wing plans down at the edge of the work bench. The wing root,
next to the fuselage, should be flush with the edge of the work bench. Using a square, check to
see that the spars or trailing edge of the wing on the plans are perpendicular to the edge. The
side of the fuselage will be aligned with the work bench edge so it is important that things are
square.
1 . Locate a 3/8" sq. x 42” spruce stick and find the center. From the center measure out 1-
1/2” each way and mark. Align marks with outside edges of fuselage. This is the rear
spar in the wing. Install it in the middle 3/8" sq hole in the fuselage (the rear most 3/8 hole is for
the tail balsa, use the 3/8 hole in front of that one), making sure it is
centered, and CA in place.
2. Locate the 3/8” x 24” spruce stick and cut to a 22 1/2” length. Find the center, measure
out 1-1/2" each way and mark. Slide this spar in the forward 3/8" square hole (not the
diamond shape hole) in the fuselage, under the servo rail, making sure the marks are aligned
with the outside fuselage sides. CA in place.
3. Find the sheets with the ribs. Carefully cut them out so as not to break off the tabs. If you
do break one off, CA it back on. These tabs are required to space the ribs parallel to the work
surface during wing construction. Lightly sand edges of each. Note: When we say cut them
out, we mean cut the micro joints that hold them in the sheet. These joints keep the
parts in tact on the sheet.
4. Carefully slide Rl rib on the spars and up against the fuselage. Glue it in place with
CA but, do not glue the tabs to the sides. These must be removed later.
