55) Sand round the leading and trailing edges of the sides
and center support of the radiators. Install the two
outside ones to the bottom of the wing and glue in
place. Photo 42 shows this.
56) Trim the center support so that it clears the servo yet
still provides support. Sand round the leading and
trailing edges of the radiator bottom, then attach the
center support to it. Photo 43 shows a center support
before and after the fitting.
57) Glue the center support to the radiator bottom, then the
sides to the bottom. DO NOT glue the center support
to the wing itself. In the event of a servo failure, you
will need to neatly slice the sides, but you don’t want to
slice the center piece (it’s hard to do neatly – know how
I learned that?). If you wish, you may place a small
dab of thick CA to hold the servo in place. It is up to
you and how closely you fit the support to fit the servo.
58) Fit the wing to the fuselage now using epoxy to glue
them. Make sure that they fit snugly, and that the
fuselage sides are vertical when the wings are level.
59) Fit the chin block to the motor mount and wing leading
edge, removing small sections as shown in Photo 46 to
make it fit both parts. The wing/chin joint will
probably require a little putty to get a smooth finish.
60) Carve and sand the chin block to shape.
61) Using the side view of the plans as a guide, use your Dremel tool with a sanding drum to open a passage
for air in the chin block. The hole should have the front and rear angled so as to permit the easy flow of
air into the fuselage. Do not cut into the wing.
62) Round off the leading edges of the air scoop now.
