Great Planes Giant Aeromaster Kit - GPMA0502 - Manual (Page 24)

D D 1. Position a piece of wax paper over the right aileron
plan. Trim a 3/32" x 3" x 36" balsa sheet 2-1/8" wide. From
the narrowed balsa sheet, make a top and bottom aileron
sheet. Cut the sheet 1/16" longer than the plan. Pin one of
the sheets in position over the plan.
D D 2. Use thin CA to glue the eight die-cut 3/32" balsa
aileron ribs perpendicular to the bottom sheet and flush
with the LE. Use the marks on the plan to align the ribs.
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 cross-section.
D D 6. Draw a centerline on the sub TE of each aileron
bay on the wing. Mark the hinge locations on the wing and
the aileron and cut the slots for the hinges. Test fit the
ailerons to the wing.
D 7. Go back to step 1 and build the second aileron.
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 4. If you are installing optional aileron servos in the
top wing, use medium CA to glue the tapered balsa horn
block in position. For both versions 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. Use a piece of masking tape to mark the balsa
horn block, if installed. Use the leftover 5/16" x 1" x 36"
balsa stick from the wing panel to make the aileron LE.
Sand the LE to the same angle as the sheeting and flush
with the end ribs.
