Step 58 - Elevator Assembly (E1)
Locate four E1’s from BP1. Two are
used to create the outer edge of each
elevator half. Glue one on top of the
other, then to the leading edge pieces
you just installed.
Pay close attention to their orientation.
Step 59 - Elevator Assembly (bracing)
Using 1/4” square balsa, measure,
cut and glue in center bracing of both
elevator halves. Check your scrap pile
using any possible shorter lengths
first before reverting to longer, uncut
lengths.
Step 60 - Elevator Assembly (joiner)
Locate the 1/4” dowel, then measure, cut
and glue it in place to join both elevator
halves into a single elevator. Make sure
this joint is strong and fully cured before
removing it from the work surface.
Step 61 - Elevator Assembly (E2)
Locate four E2 from BP1. Glue one on
the outer portions of leading edge, then
glue another E2 on top of each one as
shown here.
Prepare your work area
Now tape the rudder/fin plan and a fresh piece of waxed paper on
your building board.
Step 62 - Rudder Assembly (leading edge)
Using 1/4” x 1/2” balsa, measure, cut and pin
both the leading of the rudder to your building
surface. Check your scrap pile using any possible
shorter lengths first before reverting to longer,
uncut lengths.
Step 63 - Rudder Assembly (VF4)
Locate both VF4’s from BP1. Glue one on
top of the other, then to the leading edge -
paying close attention to it’s orientation.
Step 64 - Rudder Assembly (VF3)
Locate both VF3’s from BP1. Glue one on
top of the other, then to the leading edge.
Pay close attention to it’s orientation.
Step 65 - Rudder Assembly (inner support)
Using scrap 1/4” x 1/2” balsa, measure,
cut and glue this internal support into
the rudder as shown.
Step 66 - Rudder Assembly (bracing)
Using 1/4” square balsa, measure,
cut and glue in center bracing of the
rudder. Check your scrap pile using
any possible shorter lengths first
before reverting to longer, uncut
lengths.
Remove the rudder from the board,
then make a notch in the leading edge to give clearance for the
elevator (see plans). Also make a notch in the trailing edge of the
horizontal stab to give clearance for the vertical fin’s trailing edge.
(see plans).
Step 67 - Vertical Fin Assembly (trailing edge)
Using 1/4” x 1/2” balsa, measure, cut and pin both the trailing
edge of the vertical to your building surface. Again, use scrap
pieces before longer, uncut lengths if possible.
Step 68 - Vertical Fin Assembly (VF1/VF2)
Locate two VF1’s and two VF2’s from
BP1. VF1 is the top edge and VF2 is
the bottom edge of the vertical fin.
Glue one of each in position, then
glue the other on top as shown.
Pay close attention to their
orientation.
Step 69 - Vertical Fin Assembly (leading edge / bracing)
Using 1/4” square balsa, measure, cut
and glue the leading edge first, then
the center bracing of the vertical fin.
Check your scrap pile using any possible
shorter lengths first before reverting to
longer, uncut lengths.
This completes assembly of the Sunday Fighter tail surfaces.
Now it’s time to start construction of the fuselage.
Prepare your work area
Now a fresh piece of waxed paper on your building board. You’ll
also need the fuselage plans as a reference. No need to tape them
to the board as they’re more for reference.
Step 70 - Fuselage Assembly (fuse sides)
Locate both FS3’s from BP5 and BP7, and both
FS4’s from BP6 and BP8.
One FS3 is glued to one FS4 as
shown here to form a fuselage
side sheet. Then do the same
to create the other side sheet.
Make sure the joints are perfectly flat and the top edge of each
sheet is perfectly straight while the glue cures.
Step 71 - Fuselage Assembly (F3 & F4)
Locate F4 from LP2 and F3 from LP3.
These are glued on top of each other
as shown. Make sure they are perfectly
aligned and keep any glue out of the pre-
cut slots and holes.
