2.2 Cutting Control Surface Bevels
•
Parts
Required:
o
Horizontal
Fuselage
o
Aileron
(2x)
o
Rudder
1)
Bevel
the
hinged
control
surfaces,
using
steel
rulers
and
fresh
single
‐
edge
razor
blades.
Set
a
12
‐
inch
or
longer
metal
ruler
backing
at
the
edge
of
your
workbench.
Lay
the
foam
part
to
be
beveled
on
the
ruler,
aligning
the
edge
of
the
ruled
and
the
edge
of
the
foam
nearest
to
you.
Lay
a
second
steel
ruler
facing
down
far
enough
back
to
expose
enough
foam
to
allow
a
45
degree
slice
to
be
removed.
Cut
the
foam
with
the
single
‐
edge
razor
blade
held
against
both
rulers.
Angling
the
blade
makes
a
smoother
cut.
Both
ailerons
will
be
beveled
on
their
leading
edges,
ensuring
that
they
are
mirror
images
of
each
other.
The
rudder
will
be
beveled
on
its
leading
edge,
but
the
bevel
should
be
cut
out
of
the
right
side
of
the
part.
Place
the
rudder
with
its
left
side
down
on
the
table
and
cut
the
bevel
from
the
right
side.
The
rear
of
the
horizontal
fuselage
will
be
beveled
on
the
bottom
side
of
the
part.
Place
the
fuselage
with
its
top
side
down
on
the
table
and
cut
the
bevel
from
the
bottom
side.
EPP
foam
dulls
blades
surprisingly
fast,
so
be
prepared
to
change
to
a
fresh
blade
when
you
detect
snagging
or
excess
drag
as
you
make
your
cuts!
