BUILDING
THE
MODEL
Before
Starting
A
note
about
the
photos:
The
photos
were
taken
of
a
prototype
and
the
parts
supplied
may
look
slightly
different
from
them.
However,
the
concepts
illustrated
are
the
same.
John
Boeck
built
the
Fokker
Dr.I
prototype.
COWLING
Begin
construction
of
the
cowl
by
gluing
C1
and
C2
to
a
strip
of
1/32”
ply
with
the
grain
of
the
plywood
running
the
short
way.
After
the
assembly
is
secure,
trim
off
the
bottom
ends
of
C2
as
indicated
on
the
plan.
Glue
two
C3
ʹ
s
together
with
C4
and
glue
this
assembly
to
the
C1/C2
assembly
and
sand
to
shape.
WINGS
Wing
Construction
Pin
down,
over
the
plan,
the
pre
‐
cut
trailing
edge
plywood,
spars
and
wing
tip,
gluing
as
required.
Add
the
leading
edge
stock.
Sand
the
leading
edge
stock
to
be
rounded
and
meet
the
ribs.
The
middle
wing
spars
are
to
be
left
extending
as
shown
on
the
plans.
The
spars
serve
in
the
alignment
of
the
middle
wings
to
the
fuselage.
The
bottom
wing
halves
are
built
with
spars
connecting
them
over
the
plan.
Keep
them
bottom
wing
in
one
piece
for
strength.
Top
Wing
Construction
Detail
The
Ailerons
are
driven
by
in
wing
servos.
The
ailerons
are
formed
from
a
laser
cut
sheet
of
balsa
and
reinforced
with
small
riblets.
IP
mounts
are
built
from
two
balsa
side
ribs
and
two
inner
half
ribs,
making
a
slot
for
the
ply
IP
struts
provided.
Scalloping
is
pre
‐
set
by
the
top
and
bottom
ply
trailing
edge
parts
supplied.
