on the plans to obtain the shape of the rudder.
Use a razor plane and sanding block to “rough in”
the shape of the rudder. Final shaping and fitting
should be done after the fin is glued onto the
fuselage, but you may wish to tape the rudder to
the fin at this point to blend the tips of both.
BUILD THE WING
NOTE: The wings are built “UPSIDE-
DOWN” on the plans. The jig tabs are
attached to what is, in the end, the
TOP surface of the wing.
VERY IMPORTANT! Since it is the
standard convention to show the Top
View of the wing, and the wing panels
are built upside-down, the LEFT wing
panel is built over the RIGHT Wing Top
View and vice-versa. This does not
present any problems. Just be sure to
build a left and a right wing.
1. Place the wing plan on your building board
and cover it with waxed paper (you may wish to
cut the wing panel sections of the plan apart to
make handling easier.)
2. Hold the 1/4" x 3/8" x 36" balsa Spars over
the wing plans. Mark the Spars about 1/4" longer
than they need to be. Cut off the spars at the
marks and save the excess for the Flap Servo
Mounts.
3. Punch out all the die-cut 3/32" balsa wing
R i b s . S m o o t h o u t a n y i m p e r f e c t i o n s w i t h
sandpaper. Be sure to keep the jig tabs attached
to the ribs.
4. Ribs W-1 through W-8 have punch marks
j u s t a f t o f t h e s p a r t h a t l o c a t e t h e a i l e r o n
pushrods for you. Drill a 3/16” hole at each of
these marks.
5. Drill 1/8" holes through the punch marks in
the two die-cut 1/8" plywood Aileron Bellcrank
Plates (AB). Assemble the bellcrank parts as
shown in the sketch, making a left and a right
plate. Be sure to put a drop of 5-minute epoxy
on the 4-40 nut and threads to prevent the
bellcrank from vibrating loose.
6. Taper one end of each of the four 1/8" x
3/8" x 18" balsa Spar Doublers to match the spar
detail drawing on the plans. Glue a Spar Doubler
to each Spar with the root (non-tapered) end of
the doubler aligned with the root end of the Spar.
7. Center the die-cut 3/16" balsa Aft
Aileron Trailing Edge (A) on the die-cut 3/16"
balsa Forward Aileron Trailing Edge (F) and
glue them together with thin CA. Use a sanding
block to taper the two pieces slightly as shown in
the cross sectional drawing on the plan. These
pieces are die-cut slightly long to allow you to trim
off any imperfections.
