Sicherheitshinweise

☺ Prüfen Sie vor jedem Start den festen Sitz des Motors und der Luftschrauben - insbesondere nach dem Transport, härteren

Landungen sowie Abstürzen. Prüfen Sie ebenfalls vor jedem Start den festen Sitz und die richtige Position der Tragflächen auf

dem Rumpf.

☺ Akku erst einstecken, wenn Ihr Sender eingeschaltet ist und Sie sicher sind, daß das Bedienelement für die Motorsteuerung auf

"AUS" steht.

☺ Im startbereiten Zustand nicht in den Bereich der Luftschraube greifen.

Vorsicht in der Luftschraubendrehebene - auch Zuschauer zur Seite bitten!

☺ Zwischen den Flügen die Motortemperatur durch vorsichtige Fingerprobe prüfen und

vor einem Neustart den Motor ausreichend abkühlen lassen. Die Temperatur ist richtig, wenn Sie den Motor problemlos berüh-

ren können. Insbesondere bei hohen Außentemperaturen kann dieses bis zu 15 Minuten dauern.

☺ Denken Sie immer daran: Niemals auf Personen und Tiere zufliegen.

Conseils de sécurité

☺ Avant chaque décollage, vérifiez la fixation du moteur et de l'hélice, notamment après le transport, après les atterrissages violents

et après un “Crash”. Vérifiez également, avant chaque décollage la fixation ainsi que le positionnement de l’aile par rapport au

fuselage.

☺ Ne branchez l’accu de propulsion que si vous êtes sûr que votre émetteur est allumé et que l’élément de commande moteur est

en position “ARRET”.

☺ Ne mettez pas vos doigts dans l’hélice! Attention à la mise en marche, demandez également aux spectateurs de reculer.

☺ Entre deux vols, vérifiez en posant un doigt dessus, la température du moteur, laissezle refroidir suffisamment avant le prochain

décollage. La température est correcte si vous pouvez maintenir votre doigt ou votre main sur le moteur. Le temps de

refroidissement peut varier jusqu’à 15 minutes s’il fait particulièrement chaud.

☺ Pensez-y toujours: ne volez jamais vers ou au-dessus des personnes ou des animaux.

Safety notes

☺ Before every flight check that the motor and propeller are in place and secure - especially after transporting the model, and after

hard landings and crashes. Check also that the wing is correctly located and firmly secured on the fuselage before each flight.

☺ Don’t plug in the battery until you have switched on the transmitter, and you are sure that the motor control on the transmitter

is set to “OFF”.

☺ When the model is switched on, ready to fly, take care not to touch the propeller. Keep well clear of the propeller disc too, and ask

spectators to stay back.

☺ Allow the motor to cool down after each flight. You can check this by carefully touching the motor case with your finger. The

temperature is correct when you can hold your finger on the case without any problem. On hot days this may take up to 15

minutes.

☺ Please keep in mind at all times: don’t fly towards people or animals.

Note di sicurezza

☺ Prima di ogni decollo controllare che il motore e la eliche siano fissati stabilmente - specialmente dopo il trasporto, atterraggi

duri e se il modello è precipitato. Controllare prima del decollo anche il fissaggio e la posizione corretta delle ali sulla fusoliera.

☺ Collegare la batteria solo quando la radio è inserita ed il comando del motore è sicuramente in posizione ”SPENTO”.

☺ Prima del decollo non avvicinarsi al campo di rotazione della eliche. Attenzione alla eliche in movimento - pregare che eventuali

spettatori si portino alla dovuta distanza di sicurezza!

☺ Tra un volo e l’altro controllare cautamente con le dita la temperatura del motore e farli raffreddare sufficientemente prima di

ogni nuovo decollo. La temperatura è giusta se si possono toccare senza problemi. Specialmente con una temperatura esterna

alta questo può durare fino a 15 minuti.

☺ Fare attenzione: Non volare mai nella direzione di persone ed animali.

Advertencias de seguridad

☺ Compruebe antes de cada despegue que el motor y la hélice estén fuertemente sujetados, sobretodo después de haberlo

transportado, de aterrizajes más fuertes así como después de una caída. Compruebe igualmente antes de cada despegue que las

alas estén bien sujetas y bien colocadas en el fuselaje.

☺ Conectar la batería, cuando la emisora esté encendida y Usted esté seguro que el elemento de mando para el motor esté en

”OFF”.

☺ No meter la mano en la zona inmediata a la hélice cuando el avión esté a punto de despegar. ¡Cuidado con la zona de la hélice!

¡Pedir a los espectadores que se aparten!

☺ Entre los vuelos hay que comprobar cuidadosamente la temperatura del motor con el dedo y dejar que el motor se enfríe antes

de volver a despegar. La temperatura es correcta, si puede tocar el motor sin problemas. Sobretodo en el caso de temperaturas

del ambiente muy altas, esto puede tardar unos 15 minutos.

☺ Recuerde: No volar nunca hacía personas o animales.

Building instructions

1. Examine your kit carefully!

MULTIPLEX models are subject to constant quality checks throughout the production process, and we sincerely

hope that you are happy with the contents of your kit. However, we would ask you to check all the parts before you start

construction, with reference to the parts list, as we cannot exchange components which you have already worked on.

If you find any part is not acceptable for any reason, we will readily correct or exchange it once we have examined it. Just

send the component to our Model Department. Please be sure to include a brief description of the fault.

We are constantly working on improving our models, and for this reason we must reserve the right to change the kit

contents in terms of shape or dimensions of parts, technology, materials and fittings, without prior notification. Please

understand that we cannot entertain claims against us if the kit contents do not agree in every respect with the instructions

and the illustrations.

Caution!

Radio-controlled models, and especially model aircraft, are by no means playthings in the normal sense of

the word. Building and operating them safely requires a certain level of technical competence and manual

skill, together with discipline and a responsible attitude at the flying field. Errors and carelessness in

building and flying the model can result in serious personal injury and damage to property. Since we, as

manufacturers, have no control over the construction, maintenance and operation of our products, we are

obliged to take this opportunity to point out these hazards, and to emphasise your personal responsibility.

Important:

This model is not made of styrofoam but polypropylene particle foam!

This material cannot be joined using white glue. Epoxy resins are reasonably effective provided that the foam surfaces

are well sanded beforehand. However, we recommend the use of hot-melt adhesive and a glue gun. Hot-melt glue

sticks and guns are available in many model shops, DIY shops and builder’s merchants. The most suitable glue sticks

are the soft, flexible types. Please note when using hot-melt glue: be sure to trial-fit the parts “dry” (without glue).

Apply the adhesive sparingly, and join the parts immediately. Note that an excessive application of hot glue will

damage the foam, as the heat melts the material before the glue bonds.

1. Preparation:

Carefully ease the die-cut parts out of

the sheet using a balsa knife if

necessary, clean up the edges

with abrasive paper and group them

according to the version you intend to

build. Assemble the parts “dry”,

check that they fit accurately, then glue

them together using white glue or

cyano. For the glow version it is

absolutely essential to fuel-proof the

wooden parts with thin epoxy or paint;

for the electric version this is not

necessary, but still recommended.

2. Motor mount:

When assembling the motor mount

note that the motor thrustline must be

angled to the right, i.e. part 24 must be

fitted on the right-hand side as seen

from the tail, and part 26 on the left.

Glow version

Electric version

Prepare the undercarriage mount as

follows: press all the parts out of the die-

cut sheet, trim them to fit and join them

using white glue or epoxy.

The dowels, parts 50, are not fitted until

a later stage. For the glow version it is

absolutely essential to fuel-proof the

wooden parts with thin epoxy or paint;

for the electric version this is not

necessary, but still recommended.

The next step is to release the elevators

attached to the tailplane 02, so that

they can hinge up and down. Do this

by making a careful cut with a fine-

tooth saw at right-angles to the hinge

line. Install the joiner strip 41 and the

elevator horn 82. Be sure to use hot-

melt glue and a glue gun for these

joints. Apply the adhesive sparingly and

join the parts immediately.

3. Preparing the fin and rudder:

Cut slots for the hinges 83 using a balsa

knife and glue the hinges in place using

hot-melt glue. Assemble the tailwheel

unit from parts 64, 66, 81 and 85, and

glue it in the rudder together with the

horn 82 and parts 32.

4. Completing the fuselage:

Screw the screw-hook 86 into the

wooden dowel 50 and glue the dowel

in the fuselage. Cut the RC cradle 10 to

size and trim it to fit, then fix it in place

with hot-melt glue (be sparing with the

glue to avoid warping the plastic

cradle). Extend the servo cables using

filter leads, and place them in the

fuselage. You may wish to secure the

cable ends with adhesive tape so that

they don’t get in the way as

construction proceeds. Wrap each servo

in a piece of heat-shrink sleeving or

adhesive tape, and glue them in place

using hot-melt adhesive. Install the

wooden strip 40 to reinforce the tail end

of the fuselage. Glue the prepared

undercarriage mount in place together

with the wooden dowels 50.

5. Installing the fin and tailplane

Glue the prepared fin and tailplane to

the fuselage, and fit the rear turtle-deck

at the same time. Install the plastic

sleeve 70 as shown; the receiver aerial

runs through this and is fixed to the fin

with a rubber band.

6. Preparing the wing 01

Release the ailerons by slitting with a

fine-tooth saw and carefully deflect

them to and fro until they move freely.

Wrap each aileron servo in a piece of

heat-shrink sleeving and glue them in

place using hot-melt adhesive. Thread

the servo leads into the fuselage. Check

wing alignment by measuring, and

mark the correct position. When you are

confident that everything fits correctly,

apply hot-melt glue to the fuselage /

wing joint, and immediately fit the wing

in the previously marked position. Hold

the parts exactly in this position until

the glue has set hard.

7. Control surface linkages

All four control surfaces are actuated

using the same system, as shown in Fig.

11. Connect the pre-formed end of the

pushrod to the servo output arm. Screw

the pushrod connector to the large hole

in the control surface horn, and secure

the nut with a drop of paint or similar.

Connect the control surfaces in such a

way that the full servo travel can be

exploited. The control surface travels are

stated in the section entitled “Settings”.

8. Installing the motor mount

You have already decided whether you

are building the electric or glow version

by assembling the appropriate motor

mount. The motor mount can now be

glued in place. Electric version: install

the geared motor, connect the speed

controller and carry out a test run. When

you are sure that everything is correct,

glue the “fueltank cover” 03 in place.

This is essential to provide adequate

structural strength.

Glow version: prepare and install the

fueltank (a suitable tank is available

under #72 4144). Drill an additional hole

in the fueltank cover for the fueltank

pressure line. Run the pressure line

through the hole and connect it to the

pressure nipple on the silencer. Wrap

the tank in a thin layer of foam rubber

(to avoid the fuel foaming), and then

glue the tank cover in place. This is es-

sential to provide adequate structural

strength.

9. Installing the receiving system

In the electric version the receiver

battery and receiver are installed under

the rear turtle deck, and secured using

Velcro (hook-and-loop) tape. If your

speed controller includes an

adequately rated BEC system you may

be able to manage without the receiver

battery.

Be careful! In this case there must be

no hint of stalled servos, and the control

surfaces must move freely.

For the glow version you will also need

a throttle servo. Wrap this servo in a

heat-shrink sleeve and fix it to the

battery cradle using cyano, with the

pushrod running forward to the motor.

Glue the snake outer to the motor

bulkhead and the fuselage side about

3 cm forward of the servo using a few

drops of glue.

You can adjust the Centre of Gravity

(CG) to suit the weight of the motor you

have installed by re-positioning the

receiver battery. There are three

possible positions: 1. behind the

fueltank, 2. behind the throttle servo, or

3. behind the receiver. Glow version:

pack the receiver in foam rubber and

install it under the rear turtle deck.

10. Motor cowl and canopy

Trim the canopy to fit neatly on the

canopy frame; the ideal tool for

trimming is a pair of curved scissors. You

may wish to decorate the interior of the

cabin in your choice of colour scheme

before gluing the canopy in place. A

“head and shoulders” pilot can also be

fitted.

The cabin is held to the fuselage by

means of a rubber band fitted to the

canopy frame and the hook / dowel

already fitted to the fuselage (see

overall view). Prepare the motor cowl by

cutting the openings required to suit

the glow or electric version, and the

motor you have installed. The cowl is

held in place with screws at the top and

the front.

11. Undercarriage

Fix the undercarriage in place using the

screws 91, as shown in the illustrations.

12. Final assembly,

settings

Check all glued joints and all the

linkages one last time. The CG should

be within the range 100 - 110 mm aft

of the wing root leading edge. Adjust

the battery position to achieve this, or

add lead ballast if necessary. The correct

motor thrustline is built into the motor

mount, but you may find that test flying

shows the need for fine adjustments.

Always measure the control surface

travels at the widest point of the control

surface:

Ailerons 22 mm up

18 mm down

Snap flaps

(opposite direction to elevator)

+/- 10 mm, switchable

Elevator 18 mm up

10 mm down

Rudder 30 mm left

30 mm right

First flight ...

Do not attempt to test-glide this

model!

The model should be launched at full-

throttle, either from the ground or from

your hand. Always launch straight into

wind.

For the first flight we recommend

that you ask a friend to launch for

you.

For a ground take-off allow the model

to pick up speed slowly, holding full up-

elevator all the time, and correct the

tracking with the rudder / tailwheel.

Allow the model to accelerate further

at full-throttle, then gradually return

the elevator to neutral so that the tail

rises to the horizontal. When the model

has reached lift-off speed apply up-

elevator deliberately to take off. Use the

elevator to produce a shallow climb,

maintaining good speed all the while.

When you reach a safe height, adjust

the transmitter trims as necessary so

that the model flies dead straight

“hands off”.

At an adequate altitude check how the

model responds when the motor is

switched off or throttled right back.

Carry out a simulated landing approach

at height so that you are prepared for

the model’s handling when the flight

pack runs down or the glow motor cuts.

In the initial phase don’t attempt to fly

tight turns at low altitude, especially on

the landing approach. It is always better

to land safely even if it means having

to walk some way to retrieve the model,

than to risk a crash by landing at your

feet. It is best to land the model with

the motor running at a high idle speed.

Safety

Safety is the First Commandment when

flying any model aircraft. Third party

insurance should be considered a basic

essential. If you join a model club

suitable cover will usually be available

through the organisation. It is your

personal responsibility to ensure that

your insurance is adequate (i.e. that it

covers powered model aircraft).

Make it your job to keep your models

and your radio control system in perfect

order at all times. Check the correct

charging procedure for the

rechargeable batteries you are using.

Make use of all sensible safety systems

and precautions which are advised for

your system. An excellent source of

practical accessories is the MULTIPLEX

main catalogue, as our products are

designed and manufactured

exclusively by practising modellers for

other practising modellers.

Always fly with a responsible attitude.

You may think that flying low over other

people’s heads is proof of your piloting

skill; others know better. The real expert

does not need to prove himself in such

childish ways. Let other pilots know that

this is what you think too, as it’s in all

our interests. Always fly in such a way

that you do not endanger yourself or

others. Bear in mind that even the best

RC system in the world is subject to

outside interference. No matter how

many years of accident-free flying you

have under your belt, you have no idea

what will happen in the next minute.

We - the MULTIPLEX team - hope you

have many hours of pleasure building

and flying your new model.
