D D 2. Draw lines on the sheet using the alignment
marks on the plan as a guide Align the die-cut 3/32" balsa
aileron ribs with the marks on the sheet Use thin CA to
glue the aileron ribs perpendicular to the bottom sheet
and flush with the LE.
D D 3 Use the leftover balsa TE from the wing panel to
make the TE on the aileron Glue it in position against the
aft end of the aileron ribs with medium CA Remove the
aileron from the building board and using a sanding bar,
sand an angle on the bottom sheet to match the angle of
the ribs and TE
D D 5 As described in the Building The Stabilizer
section, draw a centerline on the aileron LE Then draw a
line 1/4" back on both sides of the aileron LE Mark the
hinge locations and cut the slots for the hinges Using a
razor plane and a sanding bar, bevel the LE as shown on
the wing plans.
D U 6 Draw a centerline on the sub TE of each aileron
bay on the wing Mark the hinge locations and cut the
slots for the hinges Test fit the ailerons to the wing.
It's time to clean off your building table and take a break
before starting the top wing
D D 4 Cut the 4" tapered balsa horn block into four 1"
long pieces Use medium CA to glue the tapered balsa
horn block in position Then use medium CA to glue the
3/32" balsa top sheet to the TE , bottom sheet and flush to
the LE of the ribs Use a sanding bar to sand the LE
smooth Mark the balsa horn block location on the aileron
sheeting with a piece of masking tape Glue a 5/16" x
15/16" x 18" balsa stick to the front of the sheeting and
the aileron ribs to make the aileron LE Sand the LE to
the same angle as the sheeting Sand the sheeting and
LE flush with the end ribs.
D 1 Use 30-minute epoxy to glue the four forward and
four aft die-cut 1/16" ply rib doublers to both sides of the
two die-cut 1/8" balsa R-PT ribs Take extra care not to
get epoxy in the slots for the strut tabs.
D 2 Drill a 1/8" hole through each of the punch marks on
the die-cut 1/8" plywood cabane mounting plates.
D 3 Use 6-minute epoxy to glue the 1/4" x 1" x 2-3/8"
plywood cabane mounting plate doublers to the cabane
