area.

 

It

 

is

 

useful

 

at

 

this

 

point

 

to

 

determine

 

where

 

the

 

pushrods

 

or

 

pull

pull

 

cables

 

exit

 

the

 

fuselage

 

at

 

this

 

point

 

in

 

construction.

 

It

 

will

 

not

 

be

 

as

 

easy

 

after

 

the

 

sheeting

 

is

 

applied.

  

 

1/16

th

 

balsa

 

sheeting

 

is

 

employed.

 

Planking

 

may

 

be

 

preferable

 

to

 

sheeting.

   

An

 

excellent

 

article

 

showing

 

how

 

to

 

plank

 

is

 

found

 

here:

 

http://www.modelairplanenews.com/how_to/strip_pla
nk1.asp.

 

The

 

reference

 

is

 

also

 

found

 

on

 

the

 

plan.

 

If

 

planking

 

is

 

used,

 

use

 

3/32”

 

balsa

 

and

 

sand

 

the

 

balsa,

 

mercilessly,

 

to

 

1/16”

 

thickness.

  

 

 

Sheeting

 

Detail

 

If

 

sheeting

 

is

 

to

 

be

 

used,

 

choose

 

the

 

lightest,

 

softest

 

1/16”

 

balsa.

 

Cut

 

to

 

a

 

rough

 

shape

 

and

 

soak

 

in

 

hot

 

water

 

then

 

bind

 

to

 

the

 

fuselage

 

with

 

paper

 

towel

 

and

 

rubber

 

bands

 

and

 

let

 

dry.

  

This

 

process

 

will

 

set

 

the

 

curve

 

in

 

the

 

balsa.

 

Use

 

balanced

 

sections

 

so

 

that

 

no

 

distortions

 

occur

 

in

 

the

 

fuselage.

 

Use

 

blue/pink

 

Styrofoam

 

for

 

the

 

tail

 

end

 

of

 

the

 

fuselage

 

and

 

sand

 

to

 

shape.

  

The

 

area

 

can

 

also

 

be

 

covered

 

in

 

balsa.

  

 

After

 

the

 

fuselage

 

is

 

sheeted,

 

the

 

cockpit

 

and

 

keel

 

section

 

for

 

the

 

cockpit

 

opening

 

is

 

cut

 

out.

  

Cut

 

away

 

the

 

top

 

of

 

the

 

keel

 

and

 

formers

 

in

 

the

 

area.

 

This

 

opening

 

is

 

used

 

for

 

access

 

to

 

the

 

rudder

 

and

 

elevator

 

servos.

  

 

Dummy

 

Spandau

 

machine

 

gun

 

parts

 

are

 

included

 

in

 

the

 

kit.

 

They

 

are

 

assembled

 

as

 

shown

 

on

 

the

 

plan

 

and

 

a

 

printed

 

card

 

stock

 

“barrel”

 

is

 

wrapped

 

around

 

the

 

round

 

balsa

 

disks

 

forming

 

the

 

cooling

 

jacket.

 

The

 

guns

 

should

 

be

 

fashioned

 

with

 

the

 

spent

 

ammo

 

shoots

 

on

 

opposite

 

sides.

 

Then

 

set

 

the

 

guns

 

into

 

cutouts

 

in

 

the

 

top

 

of

 

the

 

fuselage

 

BEFORE

 

the

 

top

 

wing

 

is

 

attached.

  

 

TAIL

 

SURFACES

 

Lay

 

out

 

and

 

glue

 

parts

 

of

 

the

 

tail

 

surfaces

 

on

 

the

 

plans.

  

 

Rudder

 

and

 

Vertical

 

Stabilizer

 

 

Elevator

 

and

 

Horizontal

 

Stabilizer

 

Sand

 

the

 

tail

 

parts,

 

rounding

 

off

 

all

 

edges.

 

Don’t

 

add

 

the

 

horns

 

or

 

hinge

 

the

 

surfaces

 

until

 

after

 

covering

 

is

 

complete.

 

 

SPINNER

 

The

 

spinner

 

is

 

composed

 

of

 

fiberglassed

 

blue

 

foam.

 

The

 

spinner

 

is

 

made

 

from

 

blue

 

foam

 

which

 

is

 

tack

 

glued

 

to

 

a

 

piece

 

of

 

1/32”

 

ply.

 

Epoxy

 

a

 

short

 

1/4”

 

diameter

 

dowel

 

to

 

the

 

back

 

in

 

the

 

center

 

of

 

the

 

disk.

 

Place

 

the

 

assembly

 

in

 

a

 

drill

 

chuck

 

and

 

sand

 

the

 

foam

 

to

 

shape

 

while

 

it

 

spins.

 

Glass

 

the

 

foam

 

using

 

standard

 

glassing

 

techniques.

  

(Note,

 

Minwax

   

Polycrylic

 

is

 

an

 

excellent

 

substitute

 

for

 

epoxy).

 

When

 

the

 

epoxy

 

is

 

ready,

 

cut

 

the

 

excess

 

fiberglass

 

away.

 

Then

 

remove

 

the

 

plywood

 

and

 

carve

 

out

 

the

 

necessary

 

recess

 

for

 

the

 

propeller.

 

Drill

 

out

 

the

 

dowel

 

on

 

the

 

plywood

 

disk.

 

Glue

 

the

 

spinner

 

to

 

the

 

plywood

 

disk

 

after

 

the

 

prop

 

is

 

mounted

 

to

 

the

 

model.

 

It

 

should

 

be

 

perfectly

 

aligned

 

with

 

the

 

fuselage.

  

It

 

looks

 

complicated

 

but

 

in

 

practice

 

the

 

process

 

goes

 

easily

 

and

 

works

 

very

 

well.
