HELPFUL TIPS

AND

PRECAUTIONS

Some precautions need to be observed when building your "Viper"

to

avoid

problems.

1.)

2.)

Use a muffin tin or egg carton to separate screws. nuts. washers. etc.
This will make

it

easier to locate the correct part.

Place a mat or towel

on

the work surface where you will be building

the

kit.

This will prevent parts from rolling

oH

and will protect the work

surface at the same time.

3.) Try to avoid working over a shag

carpet

In the event that a small

part or screw should

fall onto the carpet,

it

will

be

difficult to find.

4.)

5.)

Avoid getting products like engine cleaner

or

screw lock

on

the plastic

parts. They can have a serious effect

on

your model.

Avoid operating the

• Viper • in very oold temperatures. Both resin

and

metal parts become brittle

at

low

temperatures.

In

addition.

grease

and oil

become

very

thick

causing

premature

wear

and

deficient performance.

Remove

all flashing from the parts before assembly.

METRIC NUTS AND BOLTS

All nuts bolts used throughout this k

it

are metric size. Therefore. some ol

the

notations may not

be

familiar

to

you.

An

M3

nut

is

a 3 millimeter (3mm) nut.

An M3 x 15 screw is 3mm diameter and 15mm long. Some round parts

may

be labeled as a "4mm Washer"

(a

washer with a 4mm inside diameter) 'or a

"3mm 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 the page. For your reference. 1 millimeter equals

approximately

.039 inches.

RADIO OPERATIONAL CHECK

Thoroughly read and follow the instructions supplied wilh your radio system.
The

following instructions are a general procedure for testing the oper

ation

of

your radio system.
An operational check of your complete radio system prior to installation is a

must. This check

will locate possible defective components BEFORE t

hey

are

installed in your model.

•

Gently plug the switch harness and servo connectors into the proper
receptacles

on

the

receiver. The connectors

are

polarized and will fit only one

way.

If they

do

not plug in easily, turn them around and try agai

n.

(DO NOT

FORCE

.)

Install the batteries I

nto

the battery holders f

or both

the transmitter

and receiver.
Unravel the receiver antenna wire and

tum

on

the transmitter, then tum

on

the

receiver switch. The servos may move a

little bit at this poi

nt

but this

is

normal.

Check to make

su

re that the transmitter is

on

when switched on. and if

it

is,

continue.

If it is

not

, recheck your installation

of

batteries. You should be able

to move the servos' a

rm

s using t

he

transmitter controls. Notice how the servos

move. They should move the same amount as you move t

he

controls. Also,

no

tice the direction of rotation of t

he

servos, then switch the servo reversing

switch

es,

if so equipped. See if the rotation

of

the servos change. They should

operate in the opposite direction

as

before.

Decide whether your radio is in prop

er

working order. If you decide that it is

defective, check the warranty procedures described in the r

ad

io instruction

manual. When turning off the system, always turn the receiver

off

first, then t

he
transmitter. This will prevent the receiver from responding to stray signals
which can cause damage.

NOTICE: Use only radio frequencies specifically allowed to operate "surface•
models such as RIC cars and boats. In the United States those frequencies fall
within the '75 MHz' or '

27 MHz' bands. Use of any other frequencies is both

ill

ega

l and dangerous.
