inkles disappear
, then go o
ver the
area again, pushing do

ring to the w

If the wr
inkles don’t go a
w
a
y, the
balsa in that area ma
y be bending inw
ard.
If this is
happening, don’t press do
wn.
Simply let the heat of the
iron shr
ink the co
ve
ring.
If the wr
inkles momentar
ily
disappear
, then immediately reappear
, the iron ma

Cut the co
v
e
ring from the holes f
or the hinge
points in the tr
ailing edge of the wing and the leading
edge of the flap and aileron.
There are three holes f
o
r
the aileron and f
our holes f
or the flap
.
N
ote that the
holes in the flap and aileron are elongated.
❏❏
5.
Shor
ten one of the pinned hinge points b
y
cutting the last segment off one end.
This hinge will
be f
or the outer
most hole in the aileron.
❏❏
6.
Without using an
y glue
, install three hinges into
the aileron.
The one shor
tened in the pre
vious step
goes in the hole nearest the outer tip
.
Note that the
piv
ot point
of each hinge m
ust align with the
center
of
the r
adius on the leading edge
.
T
o achie
v
e
this
alignment the hinges will be f
air
ly deep in the aileron.
Also note that the hinges m
ust be per
pendicular to the
leading edge
.
If necessar
y, use an electr
ic dr
ill to r
un a
3/16" [4.8mm] dr
ill bit into the holes to achie
ve
this
alignment.
Be careful not to dr
ill through the sheeting
o
ver the top and bottom of the aileron.

Again without glue
, test fit the aileron to the
wing.
Mo

[19mm] up and 3/4" [19mm] do
wn (measured at the
widest par
t of the aileron at the tr
ailing edge as sho
wn
in the photo).
If there is too m
uch resistance
, or if y
o
u
are not ab
le to mo
ve
the aileron up and do
wn 3/4"
[19mm], widen the gap betw
een the aileron and the
wing b
y
pulling the aileron from the wing slightly
, or
enlarge the hinge openings in the aileron.

8.
Still using no glue
, test fit the flap to the wing
the same w
a
y.
2-1/8" [55mm] of do
wn deflection is
required (measured at the widest par
t of the flap).
