Sicherheitshinweise

Prüfen Sie vor jedem Start den festen Sitz des Motors und der Luftschraube - 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 berühren 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.

Examine your kit carefully!

MULTIPLEX model kits are subject to constant quality checks throughout the production process, and we sincerely hope that you are completely satisfied with the contents of your kit. However, we would ask you to check all the parts before you start construction, referring to the Parts List, as we cannot exchange components which you have already modified. If you find any part is not acceptable for any reason, we will readily correct or exchange it once we have examined the faulty component. Just send the offending part to our Model Department. Please be sure to include the purchase receipt and the enclosed complaint form, duly completed. 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 usual sense of the term. 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.

Like any other aircraft, this model has static limits! Steep dives and silly, imprudent manoeuvres may cause structural failure and the loss of the model. Please note: damage caused by incompetent flying is obvious to us, and we are not prepared to replace components damaged in this way. It is always best to fly gently at first, and to work gradually towards the model’s limits. The aircraft is designed to cope with our ‘Tuning’ (upgrade) power system, but is only capable of withstanding the flight loads if it is built exactly as specified, and is in perfect structural order (i.e. not damaged). Further upgrade measures are possible, but should only be attempted if you have plenty of experience in this field, as additional structural reinforcements will be required.

Important note This model is not made of styrofoam™, and it is not possible to glue the material using white glue, polyurethane or epoxy; these adhesives only produce a superficial bond which gives way when stressed. Use medium-viscosity cyano-acrylate glue exclusively, preferably our Zacki-ELAPOR®, # 59 2727 - the cyano glue optimised specifically for ELAPOR® particle foam. If you use Zacki-ELAPOR® you will find that you do not need cyano ‘kicker’ or activator for most joints. However, if you wish to use a different adhesive, and are therefore obliged to use kicker / activator spray, we recommend that you apply the material in the open air as it can be injurious to health.

1. Before assembling the model

Please check the contents of your kit before you start working on it. You will find Figs. 1 + 2 and the Parts List helpful here.

Note: the GRP spar caps and fuselage longerons 11.1 - 11.9 are supplied in the kit in the form of a continuous strip 11 (8.5 m long), which has to be cut to length: take the dimensions of each strip directly from the component, and cut them to length using side-cutters immediately before gluing them in place. The approximate lengths are stated in the Parts List.

2. Preparing the fuselage

Lay the right-hand fuselage shell 4 down flat on the workbench (table). Cut the longeron 11.5 to length and glue it in place as shown, applying cyano along its whole length. Wipe off excess adhesive immediately using a cloth.

Fig. 03 Repeat this procedure with the left-hand fuselage shell 3.

Caution: It is absolutely essential that the fuselage shells are straight when you install the GRP longerons. If you make a mistake at this point, it will be impossible to correct it later!

3. Preparing the wing retainer plate 40

The first step here is to solder two servo leads, # 8 5133, to the M6 MUL TIPLEX high-current plug, # 8 5213, as shown in Fig. 04. Carefully separate the servo ribbon cable into its individual colours using a pair of side-cutters. Strip a little insulation from the wire ends, and tin (apply solder to) the bare conductors. Tin the individual contacts of the M6 plug. Slip a piece of heat-shrink sleeve over each wire, and solder the wire ends to the contacts in the arrangement shown in Fig. 4. Slip the sleeves over the soldered joints and shrink them in place using a heat-gun or similar.

Note that the M6 plug and socket should be fitted together before you carry out the soldering - this ensures that the contacts take up their optimum position.

4. Fitting out the fuselage

Now we turn to the right-hand fuselage shell 4. First cut the inner fuselage longeron 11.8 to length, and glue it in place using cyano. The next step is to glue the canopy latches 22 in place, taking care to position them accurately . Glue the prep ared wing retainer plate 40 in place with the projecting spigots flush at the top. Deploy the leads as shown, and tape them to the fuselage sides. Repeat this procedure with the left-hand fuselage shell 3 - with the exception of the wing retainer plate 40. Fig. 05

5. Preparing the servo installation in the fuselage

The Blizzard features a V-tail which can be actuated using a single servo (‘elevator’ function only; no rudder) or two servos. In the former case there is no need to cut away additional material, as shown in Fig. 06. If you wish to use both functions of the V-t ail (rudder and elevator), a second servo is required. In this case you have to open up the additional servo well using a balsa knife.

Fig. 06

The servo cases can now be sealed with adhesive tape, and glued in their recesses as shown in Fig. 07. Before you do this, use side-cutters to remove the superfluous arms from the servo output levers, and snip off the servo leads close to the plugs. Lengthen the cables by soldering 300 mm extension leads to them; insulate each soldered joint with a separate heat-shrink sleeve.

6. Completing the fuselage

Check that the fuselage shells fit together accurately, then glue them together using cyano.

Fig. 08

7. Installing the nose fairing / motor bulkhead

Sand off the moulding pimples from the area of the fuselage where the nose fairing / motor bulkhead 13 will fit. Apply cyano to the mating surfaces, and glue the fairing / motor bulkhead 13 in place, taking care to position it accurately. Press the fuselage against the fairing 13 from the inside while the glue is setting.

Fig. 09

Tin the contacts of the plug, solder the wires to the contacts, and shrink the sleeves over the soldered joints. Position the plug carefully and glue it in place. Push the nuts 32 into the wing retainer plate 40 until they snap into place.

The standard wire colours of UNI servo leads: red red + black brown yellow orange

8. Installing the rear fuselage fairing

Here again sand off the pimples at the joint areas. Apply cyano to the mating surfaces, position the fuselage fairing 14 carefully, and hold it firmly in place until the adhesive hardens.

Fig. 10

9. Preparing the V-t ail panels 7 + 8

Cut a slot about 1 mm wide at the end of each V-tail panel to release the control surfaces, but take great care not to cut right

through the integral hinge! Move the panels to and fro repeatedly to ease the hinge. Glue the top spar caps 11.2 in both t ail p anels.

Fig. 11

10. Installing the control surface horns

Assemble the swivel horns as shown in Fig. 12, and glue them in the appropriate recesses in the tail control surfaces. Note that the horn holes should face the servo, so that they line up correctly with the hinge pivot axis.

11. Installing the t ail p anels

The tail panels 7 + 8 have to be glued to each other in the centre and to the fuselage tail fairing 14. Take care here: all the joints should be neat, accurate and without gaps. The bottom spar caps 11.1 can now be fitted, as shown in Fig. 14.

12. The ballast chamber

“Adequately powered” electric gliders often require tail ballast. We have a neat solution in our resealable ballast chamber cover

41, which is secured using the screw 34.

13. Additional fuselage reinforcements

Glue the bottom fuselage longeron 11.6 to the underside of the fuselage.

Fig. 16 Glue the top fuselage longeron 11.7 to the top of the fuselage. Fig. 17

14. V-t ail control surface linkages

If you have installed a pair of servos for elevator and rudder control, you will need to use the two pre-formed pushrods 30. Set the servos to centre from the transmitter, and connect the pre-formed end of the pushrods to the output arms. Shorten the wire pushrods if necessary, slip the ends through the swivel connector barrels, and fit the grubscrews to secure them.

Fig. 18

2nd variant - elevator only. In this case the wire pushrods 29 are required: they are installed as shown in Fig. 19.

e. Immediately wipe off excess glue where it is squeezed out of the channel. f. If necessary, flex the wing away from the spar slightly, across the chord, and apply more glue.

Fig. 21

16. Additional wing reinforcements

The bottom spar cap 11.3 can now be glued to the underside of the wing: lay the wing down flat with the curved tips extending over the ends of the workbench before installing it. Fig. 22 Now turn the wing over and glue the top spar cap 11.4 in the sp ar slot. It is a good idea to curve the spars beforehand where they fit in the wingtip area. Fig. 23

Twenty diagonal braces 11.9 have to be glued to the top and bottom of the wing in a ‘herringbone’ pattern; this is a special measure designed to increase the torsional rigidity of the wing. Please take great care over this procedure, and in particular glue each brace to the top and bottom wing spars 11.4 + 11.3. The diagonal braces are easier to install if you curve them to the approximate shape beforehand.

Figs. 24 + 25

Completing the wing

17. Wing centre section doubler

Sand off the pimples on the central area of the wing where the centre section doubler 15 fits, and glue the doubler in place using cyano.

Fig. 26

18. Installing the aileron servos and the M6 socket

Temporarily place the servos in their recesses. Cut the servo leads to the correct length and position them in the wing together with the green M6 socket, as shown in Fig. 27.

Caution: check the wire assignment carefully; the insulation colours on the plug and socket must match up correctly.

15. Preparing the wings

The first step here is to glue the wing panels 5 + 6 together in the centre as shown. Ensure that they line up exactly . Any error at this point will seriously affect the model’s flying characteristics.

Fig. 20

The following preparatory work is necessary before you install the rectangular carbon fibre wing spars 9 + 10: Lay out all the parts where you can reach them easily - the wing, the spars, adhesive, a cloth - and clear away everything else which could get in the way. Since the spars are a very close fit in the wings, they displace most of the adhesive when pressed into the recess; this causes the glue to set very quickly. If you make a mistake at this point, you may not be able to press the spars into position before the glue sets.

Caution: the spars lie below the wing surface over part of their length (dihedral). The exposed slots are covered later by the stickers 16.

This procedure is crucial, and that is why we describe it very carefully below. Please note that we will not replace spoiled parts which result from using the wrong procedure!

a. Trial-fit the spars, i.e. press them into their slots ‘dry’ (without glue). b. Apply the adhesive (e.g. Elapor cyano) only to the bottom of the spar slot in the wing. c. Lay the wing down flat. d. In one swift process, press the spar into the spar slot as far as it will go.

Back to the soldering iron! Carefully separate the servo ribbon cable into its individual colours using a pair of side-cutters. Strip a little insulation from the wire ends, and tin (apply solder to) the bare conductors. Tin the individual contacts of the M6 socket. Slip a piece of heatshrink sleeve over each wire, and solder the wire ends to the contacts in the arrangement shown in Fig. 27.

Slip the sleeves over the soldered joints and shrink them in place using a heat-gun or similar. Press the servos into their wells, and secure them with a drop of cyano at each mounting lug. Deploy the servo leads in the servo lead ducts, pressing them into place with a blunt, flat instrument. Place the connector in the holder and glue it in place as shown.

Ensure in particular that not the tiniest trace of adhesive gets onto the surfaces which later come into contact with the mating half of the connector, i.e. apply the glue to the socket holder only.

19. Concealing the wing spars

Part of the main spar lies below the surface of the underside of the wing; these channels can be covered by applying the stickers

16. The stickers improve the look of the model, and compensate for the stepped height of the surface.

Fig. 28

20. Aileron linkages

Assemble the aileron horns from parts 24, 25 and 26, as shown in Fig. 29, and carefully glue them in the appropriate recesses in
