hubs

 

are

 

provided

 

that

 

are

 

to

 

slip

 

over

 

the

 

brass

 

tubing

 

as

 

shown.

  

Alternatively,

 

gluing

 

an

 

additional

 

½”

 

square

 

piece

 

of

 

scrap

 

1/8”

 

balsa

 

with

 

a

 

hole

 

drilled

 

in

 

the

 

center

 

can

 

be

 

substituted.

 

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.

and

 

Aligning

 

Wing

 

Panels

 

The

 

first

 

task

 

is

 

to

 

epoxy

 

the

 

lower

 

wings

 

accurately

 

onto

 

the

 

fuselage.

 

Use

 

5

minute

 

epoxy

 

for

 

this

 

task.

  

Apply

 

epoxy

 

to

 

the

 

wing

 

rib

 

that

 

meets

 

the

 

fuselage.

 

Attach

 

the

 

wings

 

to

 

the

 

fuselage.

 

Use

 

the

 

locating

 

dowels

 

to

 

assist

 

with

 

aligning

 

the

 

wing

 

panels.

  

Allow

 

epoxy

 

to

 

set.

  

 

After

 

the

 

lower

 

wings

 

are

 

attached,

 

the

 

struts

 

are

 

inserted.

 

The

 

top

 

wing

 

is

 

added

 

and

 

epoxied

 

in

 

place.

 

The

 

triangular

 

formers

 

aid

 

in

 

getting

 

the

 

wing

 

incidence

 

accurately

 

placed.

and,

 

with

 

both

 

the

 

servos

 

and

surfaces

 

centered,

 

glue

 

the

 

horns

 

into

Kevlar

 

fishing

 

line

 

or

 

elastic

 

beading

 

cording

 

to

 

simulate

Use

 

small

 

screws,

 

fishing

 

hook

 

eyes,

 

straight

 

pinheads

 

or

 

small

 

eyelets

 

to

 

attach

 

the

 

lines

 

to

 

the

 

mounting

 

crosspieces

 

placed

 

in

 

the

 

wing

 

during

 

assembly.

  

While

 

not

 

technically

 

required

 

these

can

 

add

 

a

 

degree

 

of

 

strength
