Great Planes Giant Extra 330L Kit - GPMA0250 - Manual (Page 37)

❏ 19. Using three 1/8" x 1/8" x 36" balsa sticks, line the
inner edge of the wing openings in the fuse outer shell
sheeting. HINT: Cut pieces to fit between the formers. Bend
this inner lining to follow the wing shape on the inside of the
sheeting (above and below the wing), giving the sheeting
additional support. Glue the strips in place.
❏ 1. Set the fuse right-side-up on your work surface.
Position FD1 into its notches and glue in place.
❏ 2. Position FD2 flush against the trailing edge of former
SF2 and tight against the stringers and longerons. Glue
it in place.
❏ 3. Position FD3 flush against the trailing edge of former
SF3, and set the angle using the IP gauge. Glue FD3 in
place. NOTE: Be careful not to glue the IP gauge.
❏ 4. From leftover 1/4" x 1/4" balsa stick, position and glue
the center top deck stringer and trim it flush with the leading
edge of FD1 and the trailing edge of FD3.
❏ 5. From six 1/8" x 1/4" x 36" balsa sticks, cut six 10" long front
deck side stringers. Note: Cut one 10" piece from each 36"
stick. Fit and glue the six side stringers and trim them flush with
the leading edge of FD1 and the trailing edge of FD3.
NOTE: Save the six 26" long pieces for the turtle deck stringers.
❏ 6. From 1/8" x 1/8" balsa stick (left over from the wing
saddle sheeting support), fit and glue two front deck
gluing stringers flush against the outer shell longerons
and tight in the notches in FD1, 2, and 3. Trim the gluing
stringers flush with FD1 and FD3 as you did the others.
❏ 7. From two 3/32" x 3" x 36" balsa sheets, cut five 11" long
sheets. Edge glue the 5 sheets together, creating one 11" x
15" front deck sheet. Sand both sides of the sheet smooth.
❏ 8. Position the sheet flat across the top of the front deck
and gently wrap the sheet to the left side outer shell
sheeting. Angle the edge of the front deck sheet until it
matches the angle of the shell sheeting. Glue the deck
sheet to the shell sheeting and to the gluing stringer.
❏ 9. Wet the outside of the deck sheet liberally with a
water/ammonia mix to help it bend. Allow the sheet to hang
over the front deck for several minutes to help it conform to
shape. HINT: A damp, heavy towel will drape over the
sheeting and help hold it in place and keep it wet as it
conforms to the deck shape.
