will

modifications.

Others

will

require

either

additional

parts

not

listed

here

or

more

than

modifications_

If

you

are pla

nning

to

use

an

aircraft

type

engine

you

MUST

supply

it

with a heat

sink

device

to

help

cool

the

engine.

Without a heatsink,

the

engine

will

overheat

and

be

destroyed.

You

will

need

to

purchase a muffler

and

manifold.

The

Kyosho

KC-32

Muffler

is

recommended

and

will

work

those

engines

listed

above.

You

must

choose

the

proper

manifold

based

upon

the

engine

you

are

using.

For

the

as

21VF-B

and

VF-C

use

the

KC-31

Manifold.

For

as

and

Enya

side

exhaust

models,

use

the

and

for

Irvine

engines

use

the

KC-44A

Manifold.

IMPORTANT!

BEFORE

YOU

BEGIN

A WORD OF WARNING

is

necessary, especially

if

this happens

to

be

your

first gas-powered vehicle. Gas-powered cars are subjected

to

stress

and strain

due

to

J-vigh

engine RPM, rough terrain and

the

raCing/high per-

formance usage th'

at

they

receive.

As

a result,

they

need continual pre-

ventative maintenance to keep them

in

operating

condition.

This

is

a sophisticated model with a large

number

of moving parts. Before

you

begin assembl.y,

take

a look through

the

box

and these instructions

carefully

to

decide

whether

or

not

you

are ready for this challenge!

If

you

do

not

feel

that

this

type

of

model

is

for

you,

it may

be

returned

to

the

dealer as long

as

it

is

NEW

and

UNUSED. UNDER NO CIRCUM-

STANCES

CAN

YOUR DEALER ACCEPT A KIT FOR RETURN IF

ASSEMB L Y HAS ALREADY BEGUN!

If

this

is

not

what

you

bargained

for,

then

go

no

further

and

return this

kit

to

the

dealer immediately.

BUT,

if

a little ma intenance

doesn't

bother

you

and

the

thrill

of

high per-

formance

driving

is

for

you,

then

don't

hesitate

another

minute! Read

thrnlJoh this entire manual thoroughly to familiarize yourself with

the

METRIC

NUTS

AND

BOLTS

All

nuts and bolts used

throughout

this kit are metric size. Therefore,

some

of

the

notations

may

not

be

familiar to

you.

An

M3

nut

is

a 3

millimeter (3mm) nut.

An

M3

x 15 screw

is

15 mm long and

3mm

in

diameter.

Some

round

parts may be labeled

as

a "4.ji Washer" (this

would be a washer with a

4mm

inside diameter!

or a "3

% Bushing"

(a

bushing with a

3mm

inside diameter).

At

various points

throughout

the

manual these parts are labeled and pictured

in

their

actual size

on

the

left hand side

of

the

page.

For

your

reference, 1 millimeter equals ap-

proximately

.039

inches.
