Top Flite TOPA0155 - Manual (Page 50)

Fit the air intakes
❏
1. If you haven’t done so already, final-sand the
wing with progressively finer grits of sandpaper
ending with 400 or 600-grit.
❏
2. Mount the wing to the fuselage. Cut the molded
ABS plastic left air intake for the carb/oil cooler
along the cutlines. Test fit the intake to the left side of
the fuse and wing. Trim as necessary for a good fit.
Temporarily tape the intake to the wing.
❏
3. Trim and fit the right air intake for the carb to
the right side of the fuse and wing and tape it into
position the same way.
❏
4. Once satisfied with the fit of the right and left
air intakes, carefully glue them to the wing only with
thin CA.
❏
5. Cut a piece of leftover 1/8" [3.2mm] balsa to fit
between both air intakes on the front of the wing.
Position the piece of balsa between the intakes, then
use a ballpoint pen to draw the outline of the bottom
of the fuse onto the piece. This will be the wing
fillet former.
❏
6. Cut the wing fillet former along the line, then
test fit it to the wing and fuse. Trim the wing fillet
former until it is slightly smaller than the bottom of
the fuse sheeting to accommodate the ABS filler
sheet that will be glued into position later.
❏
7. Make two wing fillet ribs from leftover 1/8"
[3.2mm] balsa that fit under the edges of the air
intakes. Glue the fillet ribs and the fillet former into
position. Note that the middle of the fillet ribs aligns
with the edges of the air intakes.
❏
8. Cut out, then trim the ABS plastic fillet sheet to
fit between the fuse and the air intakes. Glue the fillet
sheet to the wing only.
