The trailing edge of
the wing tips will need
sanding.
Sand them down to
closely match the
aileron.
The leading edge is
blunt as shown here.
(You can see the line
where the marker on
the edges will now act
as a guide for you when
sanding)
With the guide line
showing you can be
sure to sand a uniform
rounded edge.
Now flip over the
bottom side and also
sand a slight taper on
the bottom outer trailing
edge of the wing. This
will create some slight
washout
You can see the red
marker lines beneath
the Depron to prevent
you from sanding too
much. Stop before it
starts showing through
too much.
Make sure you use a
sanding bar to ensure
your sanding is uni-
form and level where
needed. This helps
greatly with sanding the
tapered trailing edges.
Here you can see an-
other angle of the taper
at the bottom trailing
edge.
(Bottom side is facing
up in this photo)
More photos to show
the sanding.
Here is a shot of the
shape of the airfoil at
this point. Right now it
is “Flat Bottom” later we
will make it “semi-sym-
metrical” for better high
speed performance.
This photo shows the
wash out better.
Before we sand a bevel
to BOTH the wing and
the aileron.
