Preparation

 

Layout

 

the

 

2

 

plan

 

sheets

 

and

 

laser

 

cut

 

kit

 

parts.

 

Study

 

the

 

plans

 

and

 

identify

 

all

 

supplied

 

parts,

 

you

 

may

 

like

 

to

 

mark

 

the

 

part

 

numbers

 

beside

 

the

 

part

 

for

 

later

 

identification.

 

As

 

you

 

go,

 

prepare

 

your

 

‘stick

 

shopping

 

list’

 

of

 

stock

 

not

 

included.

 

This

 

list

 

will

 

include

 

but

 

is

 

not

 

limited

 

to,

 

such

 

as

 

wing

 

spars,

 

leading

 

edges,

 

1/8”

 

square

 

for

 

rear

 

fuse

 

section,

 

and

 

some

 

1/16”

 

and

 

1/32”

 

balsa

 

sheeting.

 

 

Plans

 

and

 

parts

 

laid

 

out.

 

During

 

construction,

 

plans

 

should

 

be

 

covered

 

with

 

some

 

sort

 

of

 

‘plan

 

protector’

 

such

 

as

 

commercially

 

available

 

types,

 

or

 

‘grease

 

proof

 

paper’

 

or

 

cling

 

wrap

 

or

 

even

 

the

 

plastic

 

bag

 

the

 

kit

 

came

 

in.

 

Glue

 

is

 

up

 

to

 

you,

 

some

 

builders

 

like

 

CA

 

glues

 

which

 

certainly

 

speeds

 

construction

 

in

 

general,

 

but

 

ensure

 

your

 

work

 

area

 

is

 

well

 

ventilated

 

as

 

many

 

people

 

have

 

adverse

 

reactions

 

to

 

the

 

poisonous

 

fumes.

 

Epoxy

 

glue

 

should

 

be

 

used

 

for

 

the

 

fuse

 

front

 

main

 

structure

 

for

 

strength

 

and

 

durability.

 

‘White’

 

wood

 

glue

 

is

 

a

 

good

 

alternative

 

to

 

CA,

 

it

 

takes

 

longer

 

waiting

 

for

 

it

 

to

 

set

 

but

 

gives

 

more

 

time

 

to

 

precisely

 

locate

 

parts,

 

avoids

 

‘stuck

 

fingers’

 

and

 

is

 

generally

 

a

 

more

 

stress

 

free

 

experience.

 

Tools

.

 

Not

 

much

 

more

 

than

 

a

 

sharp

 

knife

 

with

 

a

 

good

 

supply

 

of

 

replacement

 

blades

 

and

 

some

 

sandpaper

 

is

 

required.

 

Very

 

helpful,

 

especially

 

with

 

this

 

model

 

is

 

having

 

a

 

number

 

of

 

set

squares,

 

straight

 

edges

 

and

 

rules

 

available

 

for

 

truing

 

up

 

parts

 

as

 

construction

 

proceeds.

 

When

 

removing

 

parts

 

from

 

the

 

supplied

 

sheets

 

use

 

care

 

and

 

a

 

very

 

sharp

 

blade

 

to

 

cut

 

the

 

small

 

bridges

 

holding

 

the

 

part

 

into

 

the

 

sheet

 

before

 

removing

 

it.

 

Simply

 

pressing

 

the

 

part

 

out

 

of

 

the

 

sheet

 

risks

 

tearing

 

or

 

breaking

 

it,

 

especially

 

with

 

some

 

of

 

the

 

finer

 

parts.

 

The

 

fuse,

 

wings,

 

tail

 

surfaces

 

and

 

undercarriage

 

sections

 

are

 

all

 

constructed

 

separately

 

and

 

brought

 

together

 

at

 

the

 

assembly

 

stage.

 

It

 

does

 

not

 

matter

 

in

 

which

 

order

 

these

 

sections

 

are

 

constructed

 

but

 

normal

 

advise

 

would

 

be

 

to

 

start

 

with

 

the

 

tail

 

planes

 

as

 

that

 

tends

 

to

 

be

 

easiest

 

and

 

leads

 

into

 

wing

 

then

 

fuse

 

construction.

 

This

 

would

 

be

 

good

 

advise

 

if

 

you

 

are

 

not

 

familiar

 

with

 

Aerodrome

 

RC

 

kits.
