Front

 

of

 

Fuselage

  

The

 

engine

 

sits

 

on

 

another

 

bit

 

of

 

1/16”

 

sheet

 

that

 

is

 

slightly

 

lowered

 

(to

 

roughly

 

the

 

top

 

of

 

the

 

fuselage

 

sides).

  

Of

 

course,

 

this

 

must

 

be

 

fitted

 

before

 

you

 

add

 

the

 

top

 

sheeting.

 

Tail

 

Surfaces

  

These

 

structures

 

are

 

built

 

from

 

supplied

 

laser

 

cut

 

parts

 

and

 

a

 

bit

 

of

 

builder

 

supplied

 

strip

 

stock.

 

 

 

Horizontal

 

Stabilizer

 

and

 

Elevator

 

Use

 

slightly

 

harder

 

balsa

 

for

 

the

 

trailing

 

edge

 

of

 

the

 

horizontal

 

stabilizer

 

as

 

this

 

would

 

act

 

as

 

a

 

bit

 

of

 

a

 

spar.

  

 

Rudder

 

 

Vertical

 

Stabilizer

 

The

 

rudder

 

is

 

mostly

 

from

 

the

 

laser

 

cut

 

sheet,

 

again

 

with

 

strip

 

wood

 

supplied

 

by

 

the

 

builder.

 

WHEELS

 

Gluing

 

the

 

ply

 

sides

 

on

 

the

 

3/8”

 

balsa

 

core

 

makes

 

the

 

basis

 

for

 

the

 

wheels.

 

Use

 

the

 

brass

 

hub

 

for

 

alignment.

 

Epoxy

 

the

 

hubs

 

in

 

place

 

and

 

add

 

a

 

sufficient

 

amount

 

of

 

epoxy

 

around

 

the

 

base

 

of

 

the

 

hub

 

to

 

reinforce

 

the

 

connection

 

of

 

the

 

hub

 

to

 

the

 

ply.

 

Plywood

 

reinforcing

 

hubs

 

are

 

provided

 

that

 

are

 

to

 

slip

 

over

 

the

 

brass

 

tubing

 

as

 

shown.

   

Next,

 

CA

 

glue

 

the

 

neoprene

 

cording

 

together

 

to

 

from

 

a

 

“tire”.

 

Use

 

thin

 

CA

 

sparingly

 

as

 

the

 

CA

 

bonds

 

very

 

aggressively

 

to

 

the

 

rubber.

 

Press

 

the

 

CA

 

wetted

 

ends

 

together

 

for

 

an

 

instant

 

bond.

 

The

 

best

 

way

 

to

 

align

 

the

 

ends

 

is

 

to

 

glue

 

them

 

while

 

they

 

are

 

in

 

place

 

on

 

the

 

wheel.

 

Then

 

attach

 

the

 

tires

 

to

 

the

 

wheels

 

and

 

CA

 

in

 

place.

 

A

 

thin

 

bead

 

of

 

CA

 

around

 

the

 

rim

 

makes

 

for

 

a

 

secure

 

tire.

  

Paper

 

cones

 

are

 

cut

 

out.

  

Use

 

a

 

ball

 

point

 

pen

 

to

 

score

 

each

 

line

 

on

 

the

 

back

 

to

 

make

 

an

 

impression

 

of

 

“spokes”

 

It

 

is

 

helpful

 

to

 

do

 

this

 

operation

 

on

 

a

 

paper

 

tablet

 

so

 

that

 

the

 

pen

 

makes

 

a

 

good

 

crease.

 

Fold

 

the

 

paper

 

along

 

the

 

crease

 

lines

 

to

 

exaggerate

 

the

 

raised

 

lines.

 

One

 

of

 

the

 

sections

 

forming

 

a

 

wedge

 

is

 

cut

 

out.

  

Make

 

cuts

 

to

 

the

 

center

 

of

 

the

 

circle

 

along

 

a

 

pair

 

of

 

the

 

spokes.

  

Close

 

the

 

paper

 

cutout

 

to

 

form

 

a

 

cone

 

and

 

tape

 

the

 

joint

 

inside

 

the

 

cone.

  

The

 

inside

 

cones

 

may

 

now

 

be

 

attached

 

to

 

the

 

wheels.

 

The

 

outside

 

cones

 

may

 

be

 

attached

 

at

 

this

 

point

 

if

 

wheel

 

collars

 

are

 

to

 

be

 

used.

 

Alternatively,

 

after

 

installing

 

the

 

wheels

 

on

 

the

 

landing

 

gear,

 

a

 

washer

 

may

 

be

 

soldered

 

to

 

hold

 

the

 

wheel

 

in

 

place

 

and

 

then

 

the

 

cone

 

is

 

attached.

 

This

 

method

 

makes

 

a

 

very

 

nice

 

scale

 

appearance.
