Familiarise yourself with the kit!
MULTIPLEX model kits are subject to continuous material monitoring during production. We hopethat you will be happy with the contents of the model kit. However, we ask you to check all parts(against the parts list) before using them, as processed parts are non exchangeable. If a partshould not function, we will be happy, after checking the problem, to repair or replace the part. In
such a case, please send the part to our model construction department and do not forget to
enclose proof of purchase and a short description of the fault. We are continuously working on thetechnical improvement of our models. We reserve the right to modify the contents of the kit withregard to shape, size, technology, material and features at any time and without notification. Please
understand that information and figures in these instructions cannot form the basis for a legal claim.
Warning! Remotely controlled models, in particular aircraft models, are not toys in theconventional sense. Their construction and operation requires technical understanding, atleast some practical ability and care as well as discipline and self-confidence. Faults andcarelessness during construction and operation can result in injury to people and damage toproperty. Because the manufacturer has no influence over the correct assembly,
maintenance and operation w e expressly draw these hazards to your attention.

Alternatively, a similar superglue (cyanoacrylate glue) can be used, but do not use
a superglue for polystyrene.
Epoxy glues initially provide reasonable adhesion, but if loaded, the hard glue will
crack off. The adhesion is
only superficial.

Note: Remove the pages with the illustrations from the middle of the
instructions for assembly!
Important information This model is not made from polystyrene foam. For
this reason it is not possible to use white glue or epoxy glue. Please only use
a cyanoacrylate glue, preferably one which is used in conjunction with anactivator (kicker). Please use a cyanoacrylate glue (superglue) of medium
viscosity such as „ZACKi leicht verdickt“ With Elapor®, always spray one
side with the activator (kicker) – leave it to dry and cover the other side withthe cyanoacrylate glue (ZACKi). Join the parts together and fix their position
immediately.
Take care when working with cyanoacrylate glues. These glues harden within
seconds. Therefore do not touch with the fingers or allow contact to otherparts of the body. Wear protective goggles to protect the eyes! Keep out of
the reach of children!
1. Before assembly
Check the contents of the construction kit.
Fig. 1+2 and the parts list will help you with this.
RTF* : Parts marked like this are not p art of the
EasyStar # 214192 construction kit!
RTF = Ready To Fly!
2. Assembly of fuselage and motorStart with the left-hand side of the fuselage 3.
A suitable glue for all connections is a CA glue in conjunction with an activator. Fig.
3
The enclosed motor 41 is already fitted with an interference suppressor – this isadequate if the PiCO-Control 400 round UNI # 7 2292 control is used. Solder thecontroller # 7 2292 to the connection tags at the motor. Even at this stage ensurethat the motor runs clockwise (when looking at the motor shaft / if it does not, swap
over the motor tags). Glue the motor 41 into the half of the fuselage 3, making it
protrude by approx. 3 mm as is illustrated in fig. 4. Ensure that no glue gets into
the motor or covers the cooling vents! Now lay the cables to the drive battery andthe receiver at the front in the corresponding grooves in the half of the fuselage 3.
The cable must be entirely covered by the foam. Fig. 3
If you intend to use a different controller, you should improve the motor
interference suppressor in order to be on the safe side. For this purpose, a suitablesuppressor set # 8 5020 is available. If doing this, solder on a 47 nF capacitor
between the motor connection and the motor housing and another, also of 47 nF,
between the motor connections.
Now the two halves of the fuselage 3 and 4 are glued to each other – test first
without the glue that this is possible without difficulty – if necessary, correct any
problems first. Cover the gluing point on the half of the fuselage 3 with viscous glue
(cyanoacrylate) – fuselage half 4 must already have been spayed with activatorand allowed to dry – now carefully join parts 3 and 4 and align them! The fuselage
joint must be straight and must not be bent! Fig. 5
3. Installation of the canopy lockInstall locking plates 22 for the fasteners for the
canopy lock so that the locking pin 23 can later lock between plate 22 and thefuselage wall. To do this, spray the „nests“ in the fuselage with the activator andallow to dry. Then cover the locking plates with superglue and insert without delay

in the correct position. If necessary, improve the glued connection later. Fig. 6
4. Attaching the rudder horns and connections for the linkage to the elevatorand the rudder
Shorten the T-shaped part of one of the rudder horns 24 to 2.5 mm as shown in fig.
8. Insert the linkage connections 25 into the outer holes in the rudder horns 24 andfasten them using washer 26 and nut 27. Warning: Observe the direction of
installation, 1x left-hand direction, 1x right-hand direction. Tighten the nuts (but do
not over-tighten them) and then secure them with a spot (needle) of superglue.
Pre-inst all the hexagon-socket worm screw 28 in the linkage connection 25 using
the Allan key 29. Fig. 8+9
Glue the rudder horns 24 into the nests in the rudders 10 and 11 which havealready been wetted with activator– with the row of holes pointing towards the hinge line.
Fig. 8+9
5. Gluing in the elevator and the rudderThe elevator 10 and the rudder 11 areglued together at a 90° angle. Please check this, for example by means of a
set-square. Fig. 10
6. Gluing the rudder and the elevator to the fuselage
Test-fit the elevator and the rudder, without using glue, to the fuselage and checkthe fit. Observe in particular whether the elevator 10 lies flush in the fuselage andis parallel to the wing seat on the front of the fuselage.
Fig. 11 To do this, the spar connector 34 is placed across the wing seat as an aid.
Now look from the nose of the fuselage over the spar connector and align theelevator in this way. After aligning the elevator and the rudder in the way described,
glue them to the fuselage – check the alignment again and make sure that there
are no gaps!
7. Installation of the servo motors into the fuselage
Using the remote control, switch the servo motors to „neutral“ and mount the servo
motor control hornss on the motor in such a way that in the neutral position they
stick out at the sides at a 90° angle – 1x on the left-hand side, 1x on the right-handside. Now test-fit the servo motors into the fuselage. Depending on the servo motor
type used, some small adapt ations may be necessary. Press out the holes for the
servo motor cables using the round file or a spike and pull the cables into thefuselage. Shrink-fit the servo motors into the shrink installation hose or wrap themwith adhesive tape and then glue in. Note: Never omit the adhesive tape or theshrink hose. Otherwise glue might get into the servo motor and destroy it. Fig. 12
8. Rudder linkage installation into the fuselage
The rudder linkage for the elevator and the rudder consists of the external sleeve
for the Bowden pull wire 31, the internal Bowden pull wire sleeve 33 and the steel

wire with Z-bend 30 . These are fitted together and hooked using the Z-bend to theservo motor lever fig.
13. The distance to the fulcrum from the servo motor lever should be approx. 10mm.
The other ends of the steel wires 30 are pushed through the transverse holes forthe linkage connectors 25. Embed the Bowden pull wires into the fuselage and fix
the shorter external sleeve 31 as shown in fig. 13 -fig.
16. If necessary, the steel wire 30 is bent with pliers at the rudder horn fig. 16. The
external Bowden pull wire sleeves 31 are now adhered to the fuselage along their
entire length. This much increases the stability of the rudder support. Ensure thatthe Bowden pull wires run easily and that no glue can enter into the Bowden pull
wire sleeve. Finally, the servo motors are set to the neutral position and thehexagon-socket worm screws 28 are tightened at the linkage connections 25.
9. Antenna installation to the bottom of the fuselage
The connection to the antenna for the receiver is led to the bottom of the fuselage
and inserted into the plastic tube 32. For this, a hole must be pierced from the
beginni ng of the groove along the bottom of the groove to the i nside of the fuselage,
then push the antenna through from the inside and insert into the tube 32. This ismost easily done with a pointed steel wire. It is then pushed along tube 32 andstuck into the end of the antenna insulation. It may be helpful to secure the end
with a spot of superglue. At the end of the fuselage, the antenna tube is inserted
into the spike and secured along its entire length by means of adhesive tape.
Warning: Do not bend the fuselage while doing this.
Fig. 17
10. Gluing in the locking pin for the canopyPairs of locking pins 23 are inserted
into the canopy 5. The pins should point towards the inside! Apply “ZACKi leicht
verdickt” to the toothed part, but without activator! Then insert half of the locking
pins into the slots of the canopy. Immediately allow the canopy to be locked by thelocking pins in the locking plates 22 and then align without delay. Wait for approx. 1
minute and then open the canopy carefully. Spray activator onto the gluing pointsof the locking pins. Fig. 18
11. Attaching the propeller
Detach the propeller from the (black) spinner, turn over the propeller (theembossed writing will now point to the rear) and then re-insert the spinner. Pierce
the spinner with a needle from the rear to the front. This allows the air to escapeduring the later installation. The propeller is then glued onto the motor shaft using
5-minute-resin or using Endfest 300 (UHU). Fig. 19 Do not use superglue here!!!
It may cause the material to become brittle and shatter then the spinner will
detach!
12. Inserting the wingsThe spar covers 8 and 9 must be carefully glued into thewings 6 and 7. Take care not to allow any glue to touch the surfaces which will
later be inserted into the spar connectors 34. First try out the spar connectors 34,
when you are certain that there is no active glue inside the hole, the spar is to beinserted. Otherwise it might happen that you will be unable to ever dismantle themodel again. Fig. 20
13. Checking the plug-in connection
Now assemble the model by means of the sp ar connector 34 . When doing this,check the correct attachment of the wings 6 + 7 in the fuselage. If necessary
re-work carefully. Fig. 21
14. Installing flight battery and receiver
The installation of the flight battery and the receiver is as follows: The flight battery
is located in the front of fuselage nose, and behind it is the receiver. While
positioning these elements, pay attention to the location at which the center ofgravity should eventually lie according to point 17. Glue the Velcro tape (knobblyside) to the positions on the fuselage floor where the flight battery and the receiver
are to be installed. The adhesive backing of the Velcro tape is not sufficient for thispurpose; use additional superglue. The final position of the flight battery isdetermined when the center of gravity is determined. Ensure that the Velcro tapemakes good contact with the battery . If you are not working carefully here, you
might lose your battery in-flight.
Each time before take-off check that the battery is securely attached!
Test-install all the connections following the instructions for the remote control.
Insert the battery / motor controller connection plug only after switching on
your transmitter and if you are certain that the transmitter throttle control is
set to the off position.
Insert the servo motor plug into the receiver. Switch on the transmitter and connect
the drive battery to the controller and the controller to the receiver. Your controller
must be equipped with a battery eliminator circuit (BEC,this powers the receiverand servos directly from the flight battery.). Now briefly switch the motor on andre-check the direction of rotation of the propeller. (Hold the model firmly during thetest run, remove loose, light objects from behind the model.)Caution, even with small motors and propellers there is the danger of injury!
15. Adjustment of the elevator and the rudder movement
In order to make the model follow commands smoothly, the travel of the rudder andelevator movement must be adjusted correctly.
The elevator upwards (pull control stick ) approx. 5 mm and downwards(push control stick) approx. 4 mm. The rudder 10 mm to both the left-handside and the right-hand side; measure at the lowest point of the rudder on eitherside.
If your remote control does not allow this movement, you will have to adjust yourlinkage connector.
16. Decoration For decoration, a multi-color decoration sheet 2 is enclosed. The
individual words and symbols are cut out and applied either according to oursuggestion (picture on the construction kit) or according to your own ideas. Blacken
the canopy 5 to its edge using a water-proof felt tip pen.
17. Finding the center of gravity
In order to achieve stable flying characteristics, your EasyStar must balance at one
particular point, just like any other aircraft. Set up your model so that it is ready to
fly and insert the fight battery .
The center of gravity is marked and then adjusted to approx. 5mm in front of
the rear edge of the spar cover. This adjustment is equivalent to approx. 78
mm behind the front edge of the wing if measured at the fuselage. If it is
supported at this point by your fingers, the model should balance horizontally.
Corrections are possible by shifting the fight battery . Once the correct position isfound, make a mark inside the fuselage so that the battery can always be locatedin the same position. Fig. 22

18. Preparation for the first flight
Wait for a calm day for the first flight. Often the evening hours are particularly
favourable.
Before the first flight, do a radio range check!

A range check will confirm that your radio system is working properly. Transmitter
batteries and flight batteries must be freshly charged up and in accordance with
the instructions. Check before switching on the transmitter, that the channel to be
used is available and not being used by another modeler. . A helper walks awaywith the transmitter with the antenna completely pushed down.
While the helper is walking away, activate a control function. Observe the servo
motors. The non-activated servo motor should remain still up to a distance ofapprox. 35 m or 100 feet and the controlled one must follow the control movements
without delay. This test can only be carried out successfully when the radio
channel is free of interference. This test must be repeated while the motor is
running. This should lead to no more than a minor reduction in the reach. If you
are in any doubt, do not fly the aircraft. Have the system checked by aknowledgable modeler or a radio service facility. Hand the entire system (with drive
battery, switch cable, servo motors) to the service department of the manufacturerof these appliances for checking.
First flight ....
Do not attempt to launch your Easy Star without the motor running !
The model is launched with a gentle toss into the wind.
During the first flight it is best to have the support of an experienced helper.
This is the most important advice in this entire instruction manual. If at all possible
have an experienced R/C pilot put the first flight on your new model. They will trim
your Easy Star so that it will fly “hands off” allowing you to learn to fly with astable, controllable airplane. If this is not possible, double check to make sure all
your controls function correctly and in the proper direction. While holding the modelwith the wings level at shoulder height, turn on the motor to full power and gently
toss the plane into the wind. Your model should climb out and directly away fromyou at a shallow angle with the wings level. Resist the urge to “over control” themodel with large control stick movements, After a safe height has been reached,adjust the rudder and the elevator with the trims on your transmitter, so that themodel flies straight and wings level.
At a sufficient height, familiarise yourself with the reaction of the model when the
motor is switched off . Simulate landing approaches at high altitude, so that you areprepared when the drive battery runs low. At the beginning, do not try any forced
turns close to the ground in during the landing procedure. Land safely. It is betterto walk some distance to retrieve your plane than to risk crashing the model.
19. Safety
Safety is the most important rule during flying aircraft models. It is suggested you
obtain liability insurance through the Modeling Association in your Country. If you
join a club or association you will be able to join an insurance program there. Takecare to be adequately insured (for model aircraft with motor). Always maintain themodel and remote control in good working condition. Find out about the charging
technology available for the batteries you use. Make use of all the sensible safety
equipment that you are offered. Get information from our main catalogue;
MULTIPLEX products have been constructed by model aircraft pilots from theirpractical experience for practical use. Fly conscientiously! To fly closely above theheads of other people is not a sign of ability. Real experts do not need to show off
in this way. Point this out to other pilots for our common interest. . Always fly insuch a way that neither you nor others are endangered. Always remember thateven the best remote control can be disturbed by external influences. Even many
years of flying without an accident are no guarantee for the next minute of flying.
We, the MULTIPLEX team, wish you fun and success with the construction andflying of your Easy Star.

Basic information relating to model aircraft
Any aircraft, whether full-s ize or m odel, can be controlled around the three primary axes : vertical (yaw), lateral(pitch) and longitudinal (roll). When you operate the elevator, the model’s attitude alters around the lateral axis.
If you apply a rudder comm and, the m odel s wings around the vertical axis . If you m ove the aileron s tick, themodel rolls around its longitudinal axis . As our Eas yStar has considerable wing dihedral, ailerons are notrequired for roll control. In this cas e the rudder is us ed both to turn the model around the vertical axis ,and also
to roll it (longitudinal axis). External influences such as air turbulence may caus e the m odel to deviate from its
intended flight path, and when this happens the pilot mus t control the model in s uch a way that it returns to therequired direction. The bas ic method of controlling the m odel’s height (altitude) is to vary m otor s peed (m otor
and propeller). The rotational speed of the m otor is usually altered by means of a speed controller. Applying
up-elevator als o caus es the model to gain height, but at the s am e tim e it los es s peed, and this can only becontinued until the m odel reaches its m inim um airs peed and s talls . The m axim um clim b angle varies according
to the power available from the m otor.

The wing features a cambered airfoil s ection over which the air flows when the m odel is flying. In a given
period of time the air flowing over the top surface of the wing has to cover a greater dis tance than the air
flowing under it. This caus es a reduction in press ure on the top surface, which in turn creates a lifting force
which keeps the aircraft in the air. Fig. A

Centre of Gravity (CG)To achieve stable flying characteris tics your m odel aircraft mus t balance at a particular point, jus t like anyotheraircraft. It is abs olutely es s ential to check and set the correct CG pos ition before flying the m odel for the first
tim e. The CG pos ition is s tated as a dis tance which is m eas ured aft from the wing root leading edge, i.e. close
to the fus elage. Support the model at this point on two fingertips (or - better use the MPX CG gauge, # 693054); the model should now hang level. Fig. B If the model does not balance level, the ins talled components(e.g. flight battery) can be re-pos itioned inside the fus elage. Ifthis is s till not s ufficient, attach the appropriatequantity of trim ballas t (lead or plas ticene) to the fus elage nos e or tail and s ecure it carefully. If the m odel istail-heavy, fix the ballas t at the fus elage nos e; if the m odel is tail-heavy, attach the ballas t at the tail end of thefus elage.
The longitudinal dihedral is the difference in degrees between the angle of incidence of the wing and of thetail. Provided that you work carefully and attach the wing and tailplane to the fus elage without gaps , thelongitudinal dihedral will be correct automatically.
If you are s ure that both thes e s ettings (CG and longitudinal dihedral) are correct, you can be confident that
there will be no m ajor problems when you tes t-fly the m odel. Fig. C

Control surfaces, control surface travels
The model will only fly s afely, reliably and accurately if the control surfaces m ove freely and s m oothly, follow
the s tick m ovem ents in the correct “sens e”, and m ove to the s tated m axim um travels . The travels s tated inthes e ins tructions have been es tablis hed during the tes t-flying programm e, and we s trongly recom mend thatyou keep to them initially. You can always adjust them to m eet your personal preferences later on.

Transmitter controls
The trans m itter features two main sticks which the pilot m oves to control the servos in the m odel, which in turnoperate the control s urfaces . The functions are as s igned according to Mode A, although other stick modes are
pos s ible.
The trans m itter controls the control surfaces as follows : Rudder (left / right) Fig. D Elevator (up / down) Fig. E
Throttle (m otor off / on) Fig. FUnlike the other controls , the throttle stick mus t not return to the neutral pos ition
automatically. Ins tead it features a ratchet s o that it s tays wherever you put it. Pleas e read the ins tructions
supplied with your radio control s ys tem for the method of s etting up and adjusting the trans m itter and receivingsys tem.
