Frequently Asked Questions - 214334 MULTIPLEX

USER MANUAL 214334 MULTIPLEX

• The model is controlled via a remote control. No remote control is safe from radio interference. Interference may lead to a loss of control of the model. Therefore, always ensure large safety distances in all directions when operating the model. As soon as even the smallest indication of radio interference presents itself, operation of the model must be halted immediately!

• The model may only be put into operation after a complete function and range test has been successfully carried out as per the instructions for the remote control.

• The model may only be own in good visibility. Do not y in poor light or in the direction of the sun in order to avoid glare.

• The model may not be operated under the inuence of alcohol or other intoxicants. The same applies for medicines that impair perception and responsiveness.

• Only y the model in wind and weather conditions in which you can safely control it. Even with light wind, take into account that turbulence may build up on objects and have an effect on the model.

• Never y in places where this would pose a danger to others, i.e. in residential areas, near power lines, roads, and railroad tracks.

• Never direct the model at people or animals! Avoid unnecessary risks and alert other pilots to potential hazards. Always y in a manner that ensures neither you nor others are exposed to danger – even many years of accident-free ying experience are no guarantee for the next minute of ying time. Residual risks Even if the model is operated in accordance with the regulations and observing all safety aspects, there is always a residual risk. Third-party liability insurance (powered model airplane) is therefore mandatory. If you are a member of a group or association, you might be able to take out the appropriate insurance there. Ensure models and the remote control are properly maintained and are in good condition at all times. Due to the construction and design of the model, the following dangers may arise in particular: Injuries caused by the propeller: As soon as the battery is connected, the area around the propeller must be kept clear. Be aware that objects in front of the propeller may be sucked in and objects behind the propeller may be blown away. Always align the model ensuring it cannot move in the direction of other people if the motor starts up unintentionally. When performing adjustments for which the motor is running or may start up, the model must always be securely held in place by a helper.

• Crashes caused by control errors: Even the most experienced pilots can make mistakes. For this reason, only y in a safe environment and at authorized model airplane ying elds.

• Crashes caused by technical failures, undetected damage from transportation or pre-existing damage: The model must be carefully inspected before each ight. Bear in mind that technical or material failures may occur at any time. Therefore, only operate the model in a safe environment.

• Adhere to operating limits: Excessively harsh ying weakens the structure of the model and may lead to technical and material failures as well as crashes immediately or, due to 'insidious' consequential damage, in later ights.

• Risk of re due to malfunction of the electronics: Batteries must be stored safely. The safety information of the electronic components in the model, the battery, and the charging device must be observed. Safety information for MULTIPLEX airplane models

Familiarize yourself with the construction kit! MULTIPLEX model kits are subjected to constant material inspection during production. We hope that you are satised with the contents of the kit. We nevertheless ask that you check all parts (according to the parts list) before use, as used parts cannot be exchanged. If a part is not OK, we will be happy to x or replace it after verifying this. Please send the part with sufcient postage to our Service department. Be sure to include a short description of the fault along with the purchase receipt. We are continuously working on further developing the technology of our models. We reserve the right to make changes to the contents of the kit in terms of shape, dimension, technology, material, and equipment at any time and without warning. Please understand that no claims can be derived from specications and illustrations in these instructions. Caution! Remote-controlled models, particularly airplane models, are not toys in the conventional sense. Their construction and operation requires technical understanding, a minimum level of artisan skills, discipline, and safety-awareness. Errors and negligences during building and operation may result in personal injury or property damage. As the manufacturer has no influence on proper assembly, maintenance, and operation, we explicitly refer to these dangers.

Like any airplane, the model has static limitations! Nosedives and reckless maneuvers may result in damage to the model. Please note: In such cases, there is no replacement. Approach the limitations with caution. The model is tted with the propeller recommended by us but can only withstand the loads if it is built awlessly and is undamaged. Crooked – does not really exist. If individual parts are bent during transit, they can be straightened again. Here, ELAPOR® behaves like metal. If you overbend the material slightly, it springs back minimally and retains its shape. The material of course has its limits – so don’t overdo it! Crooked

does indeed exist! If you want to paint your model, you do not need any primer for pretreatment when using the EC colors. Matt paints result in the best look. Under no circumstances may the paint coats be too thick or applied unevenly, otherwise the model will go out of shape and will be crooked, heavy or even unusable! This model is not made of Styrofoam™! Therefore, adhesions using white glue, polyurethane or epoxy are not possible. These glues only stick supercially and may peel off in severe cases. Only use cyanoacrylate/ superglue of medium viscosity, preferably Zacki-ELAPOR® # 85 2727, the superglue optimized and adapted for ELAPOR® particle foam. When using Zacki-ELAPOR®, you can largely do without kickers or activators. If, however, you use other adhesives, and are unable to do without kickers/ activators, only spray outdoors for health reasons. Take care when working with all cyanoacrylate adhesives. These adhesives sometimes harden in seconds, so do not bring your ngers or other body parts into contact with them. To protect your eyes, be sure to wear protective goggles! Keep away from children! In some places, hot glue may also be used. If applicable, this is indicated in the instructions! Working with Zacki ELAPOR® Zacki ELAPOR® was developed specially for adhesion on our foam models made of ELAPOR®. In order to design the adhesion as optimally as possible, the following points should be taken into consideration:

• Avoid the use of activators. This causes the bonding to be signicantly weakened. Especially for large-scale adhesion, we recommend allowing 24 hours for the parts to dry.

• Activators must only be used for point xing. Only spray a little activator on one side. Allow the activator to ash off for approx. 30 seconds.

• For optimal bonding, sand down the surface using sandpaper (grain size 320). The electronics must be protected from water. The controller and the batteries must be sufciently cooled.

2. Cutting the reinforcement belts to length - belts (GRP)

Using a side cutter, cut one of the fuselage-GRP rods

3. Sticking in the fuselage belts

For sticking, rst apply some Zacki ELAPOR® into the recesses, then press the belts into the recesses, e.g. using a screwdriver, and apply Zacki ELAPOR® along the belts. First stick in the two adapted fuselage belts

(350 mm) at the front on the inside of the groove of fuselage halves 3 and 4. Stick the belt measuring 700 mm in length into the right fuselage half at the rear top into the groove in the back of the fuselage. Fig. 3+4

4. Sticking in the locking clips

right and left into the intended 'nests' of the fuselage halves. Fig. 5 + 5.1

5. Controller attachment (holder for cable ties)

Stick the two holders

for the cable ties into the 'nests' of the right fuselage half. To do so, apply the adhesive so that it cannot escape through the ap openings to the outside. Using the two cable ties

, the controller will later be attached to the fuselage side. Fig. 6

6. Electrical connection of the wing servos

In order to extend the servo cables and connect them to the fuselage, completely fabricated (soldered) cable sets with green MPX M6 high- current connectors are available under order no. # 1-00112. Info: The connection for this model takes place by means of a 'forced plug', i.e. the electrical connection of the servo cables is produced automatically when inserting the wings into the fuselage. This alleviates and shortens the assembly of the model and prevents the sockets from becoming mixed up and in so doing improves safety.

7. Preparing the M6 plug holder

Allow the fuselage-side cable harness (both connection cables are the same length here) to click into place with the edge of the green sockets in the locking tabs of the plug holder

. From the back (cable side) with two hot glue points, x the connector/cable unit to the plug holder and press fully and straight into the recess until cool. Fig. 7

8. Sticking in the M6 plug holder

Stick the M6 plug holder

into the intended recess of the right fuselage half. Feed through the cables between the holder and the fuselage side forward and downward and, using some masking tape, x in place on the right fuselage half near the plugs. Fig. 8

9. Preparing the fuselage servos

Now use the remote control or a servo tester to set the two servos for elevator and aileron to neutral and then mount the servo arms at right angles (90°) to the servo housing. Caution: Due to the uneven number of teeth, the servo arms are not exchangeable by 180° exactly. Therefore, be sure to adjust / mount the arms on the servo rst, and only then shorten them inversely.

10. Shortening the servo arms (elevator and rudder)

For both servos, the double arms are cut off on one side. This can be done most effectively using a small side cutter. Position the servos alongside one another and rst cut the left and then the right arm evenly. At the resulting cut surface, cut off another two 'corners' 45° to ensure the arm does not touch the housing of the servo holder

after the servo has been tted.

11. Sticking the servos into the servo holder

Stick the two servos, with the arm forward, into the servo holder

. On the servo holder 'behind' the servo, set a hot glue point in the middle and immediately press the servo into position. After this, set two hot glue points on the aps of the servos from below – ideally, the adhesive will go into the center bore holes of the servo aps (interlocking bonding). Fig. 9

12. Mounting and securing the extension cables

Connect the servo cables to the 600 mm extension cables (contained in # 1-00112 and # 1-00113). Secure the plug connection with the enclosed plug fuse (optional # 1-00137 SU 5 pcs.).

13. Sticking in the servo holder

Stick the prepared servo holder

with the two servos into the right fuselage half - feed the servo cables forward through the semicircular recesses and secure in the grommets using a little masking tape. The servo/extension cables are subsequently laid loosely in the fuselage cable shaft – allowing the servo or undercarriage to be replaced if necessary. Fig. 10 Building instructions

Stick the three recessed hinges

(pin support) into the right fuselage half. Fig. 11

15. Fuselage reinforcement tube

The underside of the fuselage is reinforced with the carbon-ber square tube

from the bulkhead up to the servo tail unit retainer

. Mark the insertion depth (approx. 18mm) on the bulkhead. Fig. 12

16. Sticking in the bulkhead and the reinforcing tube

Hint: The motor can already be screwed into the bulkhead now, as this is easier for handling. Motor cable in direction of ight at the bottom right! Then coat all the adhesive surfaces for the bulkhead

and the reinforcement tube

in the right fuselage half with viscous Zacki ELAPOR® - not forgetting the back in the retainer of the servo holder, too

. Apply adhesive to the reinforcement tube

at one end and insert the tube approx. 18 mm into the square recess of the bulkhead

- now press this entire unit immediately into the right fuselage half. Ensure that the tube and the bulkhead are completely ush with the foam and the fuselage is not bent. Now at the rear, apply more adhesive to the servo holder/CFRP tube from the outside. Between the servo holder and the CFRP tube, some distance remains in order to compensate length tolerances of the foam caused during production. Fig. 13 Before bonding it to the second fuselage half, check again that the cables are in the grommets properly and cannot become stuck to the fuselage.

17. Sticking the fuselage halves together

Proceed with caution here – this is an important step to build the model successfully. Sand down the adhesive surfaces carefully using 320 sandpaper. First t the fuselage halves together without adhesive. The fuselage must t together without any force – rework wherever necessary. Apply viscous Zacki ELAPOR® to the adhesive surface of one fuselage half – at a certain distance to the outer edge – and t the fuselage halves together immediately. Ensure they are precisely aligned. Keep the fuselage pressed together gently and straight for a few minutes. Do not carry out any bending or loading tests. The CA glue takes a few hours to reach its nal strength. Fig. 14

18. Fuselage end piece

Stick the two halves of the fuselage end piece

+ together. After weighing the model, stick the fuselage end piece to the fuselage tail. Fig. 15

19. Completing the rudder

Stick the three recessed hinges

(pin) into the rudder

. Behind this, stick in the rudder reinforcing tube

(200 mm) and cover it with the fully glued rudder cover

. Make sure that no glue gets onto the hinge pins. Fig. 16 Stick in the rudder horn

positioned forward, screw the hexagon socket set screw

into the cardan bolt

and t into the outer holes. Fig. 17

20. Mounting the rudder and connecting the rod

Position the rudder with the hinge pins precisely on the pin supports and lock into place in the fuselage by pressing forcefully from behind. Fig. 18 Hook the rudder rod

(85 mm) from below into the outermost hole on the servo arm, bring the servo and the rudder into the neutral position, and clamp the rod in the cardan bolt. Fig. 19 Hint: To release and remove the rudder, rst release the rod by loosening the clamping screw, then swing it out as far as it will go to the right, and move it a bit further until it pops out of the hinges. Electric version with propeller / glider version With the brushless propulsion set 'FunRay' # 1-00103, the electric version of the model is ideally motorized. The components in our drive set are compatible with one another and have been fully tested. If you use other batteries, controllers, motors or remote control components, you do so at your own discretion. However, in this case it is not possible for us to provide any service. Alternatively, the model can be built as a glider. To do so, the optionally available glider nose # 22 4350 is stuck to the fuselage tip. In addition, the aero-tow release # 72 3470 can be tted for aero-tows. This is, for instance, coupled with a 3/2 mm Bowden cable tube and a 1 mm steel wire.

21. Fitting the motor (from propulsion set # 1-00103)

Insert the motor with the cables into the bottom right of the bulkhead

. Screw the motor onto the bulkhead using the four screws and the washers. Fig. 20 Attach the controller and check the direction of rotation in conjunction with your remote control (still without the propeller). If you look at the front of the motor, the drive shaft must rotate counter-clockwise. If this is not the case, swap two of the three motor connections. Caution: Do not connect the drive battery connecter plug / controller until your transmitter is switched on and you are sure the operating element for the motor control is set to 'OFF'. Secure the controller with a little adhesive tape (thin strips) or a hot glue point in the shaped position. Tie the cables using two cable ties

to the Building instructions

and secure the connection cable to the fuselage side with a little hot glue. The cables are fed forward to the motor under the cross bar – be sure to x the cables to the fuselage side near the motor with hot glue.

22. Mounting the spinner and the propeller

First screw the propeller blades (in the propulsion set # 1-00103 or 1 pair of # 1-00106) using the cylinder head screws

(M3 x 20 mm) and the stop nuts

onto the propeller driver

. Tighten the screws until the propeller blades no longer have any play but can still be retracted slightly; if necessary adjust the propeller driver. Now insert the pre-assembled propeller driver on the collet chuck

shown. Then slide the entire assembly onto the motor shaft and ensure the propeller driver remains approx. 1 mm away from the fuselage. First mount the washer of the driver, then the washer

, and nally tighten the nut (M8)

. Make sure the distance between the propeller driver and the fuselage remains the same while tightening! The spinner

is afxed with the screw

23. Sticking the leading edges to the elevator units

are symmetrical and can be stuck either on the left or right. To do so, place the elevator unit halves on the table so that the front part protrudes over the edge of the table. Now draw continuous 'tracks' with Zacki ELAPOR® on both sides, inside the leading edge, approx. 2 mm away from the edge. Position the hollow needle of the adhesive on the opposite edge to the guide and apply adhesive in a straight line. Apply less adhesive toward the outside. Position the leading edge from the outside ush on the tail unit and press on it for a while. If necessary, carefully remove any escaping glue. Do the same with the other half of the tail. Fig. 22

24. Sticking in the elevator unit wing roots and the struts

Test-t the left elevator unit wing root with the catch

, and two elevator unit strut tubes

analogous to the recesses in the left and right elevator unit

. If everything ts, carefully stick these parts on all contact surfaces to the foam part. Make sure the struts are fully pressed into the slits in the foam and no glue gets into the area in which the struts of the other half will later have to be inserted. At these points, use the glue more sparingly. Caution: Do not stick the elevator halves together until you have made sure that the glue has fully hardened. This may take several hours.

25. Making the rudder hinges accessible

Move the elevator aps up and down several times in order to make the hinges smoother. Stick the left elevator unit reinforcement tube

(200 mm) into the groove of the left elevator connector

and press it into the foam while positioned at. Likewise, stick the right elevator unit reinforcement tube

(120 mm) into the right elevator connector with the horn

Caution: Do not apply any adhesive to the outer and inner sides of the plug square. Fig. 22

26. Affixing the elevator unit to the fuselage

After ensuring the glue has hardened, test-stick the elevator halves

to the fuselage and allow the locking tab to lock into place – adjust if necessary. Remove the elevator unit again. Fig. 23 To optimize the stability from the outside, re-stick, if necessary, the CFRP struts and the stainless steel tubes to the foam with a bit of Zacki ELAPOR® and put aside until fully hardened. Fix the ends with a bit of hot glue as well.

27. Preparing the elevator linkage

Mount the safety O-ring

so that it is positioned behind the four retaining collars. Screw the hexagon socket set screw

into the cardan bolt

Mount the cardan bolt in the outer holes of the rudder horn

on the elevator. Caution: Only bend the rudder horn apart until the cardan bolt can be inserted. If you bend it too far apart, the horn may break off! Never use, e.g., a large screwdriver here as leverage!

28. Connecting the elevator rod

Test-t the elevator unit to the fuselage. Hook the elevator rod

(80 mm) from above into the second hole from the inside on the servo arm, bring the servo and the rudder into the neutral position and clamp the rod in the cardan bolt. Fig. 24 Caution when disassembling the elevator unit: First release the rod by loosening the clamping screw. Then rotate the servo arm forward - feed the rod out of the cardan bolt and then release the elevator halves again by disengaging the self-locking mechanism. This is the only way to ensure the fuselage is not damaged by the cardan bolt. Hint: Depending on the stress in rough terrain, the elevator hinges may tear from the outside over time. In this case, they can be reinforced with PVC hinges order no.: 70 3202 (6 pcs.). To mount the PVC hinges, use a cutter to cut a suitable slit from the wing tip in the hinge progression and then stick in the PVC hinge with a little glue. The pivot must be on the hinge line.

29. Strut tubes in the wings

The high-strength struts are made of carbon ber material (CFRP) coated with a precision drawn aluminum tube. The strut tubes

are already tted in the wings, if necessary they should be slightly deburred on the protruding ends (sandpaper) to ensure the Building instructions

struts can be securely inserted into the opposite n when assembling the model.

30. Sticking the leading edges to the wings

From the wing tip, rst stick on the outer leading edge segment

To do so, place the wings on the table so that the front area protrudes over the edge of the table. Now draw continuous 'tracks' of Zacki ELAPOR® on both sides, inside the leading edge, approx. 2 mm away from the edge. Position the hollow needle of the adhesive on the opposite edge to the guide and apply adhesive in a straight line. Position the leading edge from the outside on the wing and press on with your ngers for some time, sliding your ngers up and down. If necessary, remove any escaping glue. Proceed in the same manner with the inner leading edge segment

31. Mounting the wing roots / retaining clips

Afx the retaining clips

to the left and right wing roots

inside the protruding border. Slide two O-rings

8 x 2 mm over the retaining clips on each side so that they are pretensioned. Fig. 26

32. Mounting the wing roots

Stick the wing roots

to the contact surfaces of the wings using Zacki ELAPOR®. Press on the ns immediately with both hands forcefully and allow the glue to set. Fig. 27

33. Affixing the leading edges to the transition segments

to the wing roots and the leading edges. To do so, apply a little glue slightly away from the edge on the inside of the lling piece and position before afxing. If necessary, remove any escaping glue. Fig. 25

34. Reinforcing the ailerons and the flaps

Stick the stainless steel reinforcement tubes

(330 mm) into the corresponding longitudinal recesses of the wings (rudder aps) (4x at with CA adhesive). Fix the ends with a bit of hot glue as well. Caution: At rst, do not apply any glue in the area of the rudder horn indentations. Fig. 28

35. Preparing and mounting the rudder horns

Screw the hexagon socket set screws

into the cardan bolts

For the ailerons (QR), insert the cardan bolts into the outer holes of the rudder horns

. When doing so, do not bend the tabs further open than necessary! For the camber-changing flaps (WK), insert the cardan bolts into the inner holes of the rudder horns

. When doing so, do not bend the tabs further open than necessary. CAUTION: Observe installation direction! Aileron (QR) => armoriented forward Camber-changing ap (WK) => arm oriented backward Apply hot glue in the recesses and immediately insert the rudder horns

and press in fully - if necessary re-stick at the side. Fig. 28+29

36. Cutting free the aileron and the camber-changing flaps

Cut the rudders free at the front sides using a cutter / backsaw and bend the rudder aps up and down several times in order to make the hinges smoother. Under no circumstances may the rudders be separated from the hinge line!

37. Preparing the aileron servos

Caution: Due to the uneven number of teeth, the servo arms are not exchangeable by 180° exactly. Therefore, be sure to adjust / mount the arms on the servo rst, and only then shorten them inversely. First position the servos electrically into the neutral position. Then mount the servo arm one tooth turned forward toward the housing (two servos mirror-inverted). This setting enables the mechanic differentiation of the ailerons. The differentiation is now mechanically attuned so that the rudder deections upward are larger than downward. In addition, the servo arms can be turned again by the same distance further out of the middle position (offset) using the transmitter. With this setting, you can achieve even larger deections upward. As a result, even larger buttery deections can be achieved. This is helpful for landing in conned spaces or ridge lifts. Fig. 28

38. Preparing the camber-changing servos (flaps)

For the ap servos, the servo arms are turned into the neutral position one tooth turned backward toward the housing (two servos mirror- inverted). The possible deection is enlarged downward as a result! Here, an offset can additionally be set on the transmitter – the rods are slightly longer in this case. Fig. 29

39. Shortening the servo arms

For all four wing servos, the double arms are completely cut off on one side and shortened on the other. For shortening, cut precisely through the third hole from the inside so that the two inner holes can still be used. This can be done most effectively using a small side cutter. For this, cut off two left and two right / mirror-inverted arms after mounting on the servos. It is necessary to shorten them to ensure the servo hoods can be mounted later.

40. Fitting the aileron / camber-changing servos (flaps)

Insert hot glue into the slits for the servo aps and immediately press the Building instructions

servos into the recesses. If required, apply more glue into any remaining slits on the aps. Then cut off any protruding hot glue ush and lay the servo cables.

41. Cable routing in the wing # 1-00112

Now guide the wing cables (with extensions of varying lengths) through the connector recesses of the wing roots toward the servo. Click the locking tab into place in the small recess of the green M6 connector so that it is almost ush with the n. The connector can remain without cabling – thanks to the small play, tolerances to the fuselage plug are compensated. Now connect the servo cable to the extensions and apply force from the servo to press them ush into the slits. The plug-in connectors go into the larger recesses. Keep the remaining cable loops in open spaces behind the wing root and, if necessary, secure with a little hot glue so that they do not protrude over the edge of the wings. Finally, stick a matt, transparent, approx. 20 mm wide adhesive strip over the cables to secure them.

42. Mounting the rudder rods

(50 mm) with the 'Z' on the servo arm into the second hole from the inside. Hook the ap rods

(60 mm) with the 'Z' on the servo arm into the second hole from the inside. Guide the other ends through the cardan bolts of the rudder horns and tighten the socket set screws

after carrying out the adjustment. For offset setting (transmitter), readjust the neutral position of the rudder aps accordingly. Fig. 28+29

43. Affixing the servo ducts

above the rods as shown in the illustration. To do so, stick the aps into the slits. Fig. 30+31

44. Canopies (EPP foam or transparent)

In the construction kit and for RR, the canopy

is made of robust, gray EEP. Consequently, you do not have to paint it and, after sticking down the brackets, it is quickly completed. Hint: Optionally, a transparent canopy with cockpit is also available. This is available as a construction kit under order no.: 1-00138.

from beneath with hot glue into the canopy

. Stick the two closure plugs

with the last serration ush into the holes / moldings in the canopy nger-grip. To do so, apply a little superglue into the slits and onto the edges and then insert the closure plugs into the slits. Make sure the brackets are parallel and at right angles in the molding on the canopy nger-grip – this is the only way to ensure they latch in on both sides and hold the canopy securely. Fig. 32

46. Completing the transparent canopy

Optional construction kit order no. # 1-00138 For an appealing and authentic look, we recommend painting the canopy frame. You can get the best results with EC® COLOR. Paint, for instance, the frame, the instrument panel, and the seat gray # 60 2806. Once the paint is dry, stick on the labels for the instrument panel and the seat precisely. Stick the two closure plugs with the last serration ush into the slits / moldings in the canopy frame. To do so, apply a little superglue into the slits and onto the edges and then insert the closure plugs. Make sure the brackets are parallel and at right angles in the molding on the canopy nger-grip – this is the only way to ensure they latch in on both sides and hold the canopy securely. Stick the canopy glass, e.g. with transparent contact adhesive, to the canopy frame. Do not allow the contact adhesive to ash off as usual; instead, apply the adhesive, immediately place the canopy on top, and x into place with adhesive strips. Allow the adhesive to dry for some time. Use the adhesive sparingly so that the frame does not become stuck to the body; if necessary, lay a thin lm between the body and the canopy frame. Finally, the canopy frame can be taped, e.g. using elastic, dark gray adhesive tape. Fig. 33

47. Preparing the retaining pin

On the retaining pin,

and only tighten to a large loop – shorten the protruding end ush so that it cannot be tightened further by accident. The loop will later be used to pull out the pin. Fig. 34

48. Assembling the wings

Connect the wings fully to the fuselage. Fix them with the retaining pin

in the fuselage between the wings. To make sure the locking pin does not become lost, afx it with a string inside the fuselage. Fig. 34

49. Mounting / removing the elevator unit

The elevator unit is secured to the fuselage with a self-locking mechanism. To open the mechanism, press the small ap forward on the underside and remove the tail unit (rst unhook the elevator rudder rod). Fig. 23

Afx the connected receiver using the enclosed adhesive tapes

to the fuselage underneath the closure plug. There is a suitable molding for the antenna on the right half of the fuselage in the rear canopy cutout. Lay the antenna ush against the canopy edge and secure with an adhesive strip. For two antennas, guide the second one backward through the air outlet of the left half of the fuselage and secure with an adhesive strip. Building instructions

51. Affixing the decals

The kit includes extensive decal sheets

. The individual letterings and emblems have already been cut out and are afxed according to our template (construction kit picture) or as desired. For positioning, there are also several pictures in the building instructions. Cut out the large decals with a little excess together with the carrier paper – carefully remove circumferential waste (transparent) around the decal. Test position the decal on the surface on which it is to be glued. After this, pull off the carrier paper from the positioning location approx. 15 cm and cut off with the scissors – the retaining carrier paper stays for the time being. Position the element at the desired location and align it on the surface with carrier paper. If everything ts, raise the decal slightly and slowly pull out the carrier paper, starting at the cut surface. Carefully smooth out the decal – do not rub immediately, only then can necessary corrections (deductions) be made. Be careful here to ensure the lm is not stretched and still ts. Then rub rmly all over and without any bubbles using a soft cloth.

52. Affixing the landing skids

The kit includes two landing skids

made of robust special adhesive lm. Stick them on at the front and back beneath the fuselage. Afx the large lm directly behind the spinner in the middle on the fuselage joint while rubbing rmly toward the outside. Stick on the smaller lm, starting approx. 10 mm away from the fuselage tail. Hint: Transfer the center markings to the oat body labels using a thin waterproof pen . This allows you to position the parts in the middle on the fuselage joint.

53. Mounting the battery

as well as the adhesive attachment strap

to x the battery securely in the model. Feed the adhesive attachment strap through one of the three grommets at the front in the fuselage beneath the CFRP square tube. If the right position has been determined, x the adhesive strips to the left and right on the CFRP tube.

54. Balancing out the center of gravity

In order to achieve stable ying qualities, your model, just like any other aircraft, must be in equilibrium at a certain position. Assemble your model, making sure it is ready to y. The center of gravity is marked 75 mm away from the front edge of the wings (hemispheres on the bottom). Using your ngers as support, pivot the model horizontally. Set the center of gravity by positioning the battery and, if necessary, by pushing in the trim weight 35 (sphere) into the fuselage tail. Due to material density tolerances and varying equipment variants (battery / transparent canopy) of the glider and the electric glider, no exact specications can be made here. Trim weight may also be necessary in the fuselage nose - this can be attached in the space behind the motor - and secured into position using, e.g., hot glue. If the right position has been found, mark the fuselage accordingly to ensure the battery is always in the same position. Then close the trim weight opening at the fuselage tail by sticking on the fuselage end piece

Fig. 15 Hint: The center of gravity can be conveniently balanced using the center of gravity scale order no.: 69 3054 .

55. Setting the rudder deflections (guidelines!)

To achieve a balanced control of the model, the size of the rudder deections must be set correctly. The deections are measured at the lowest point of the rudders. Elevator Upward (joystick pulled back) approx. +15 mm Downward (joystick pushed forward) approx. - 15 mm Spoiler (elevator downward) approx. - 3.5 mm Electric version: Gas mixture at height 0 mm Flap mixture into elevator at speed / thermal approx. - 1 / 0 mm Rudder To the left and right approx. 35 mm each Aileron Upward / downward approx. + 20 / - 9

Speed ight and aerobatic position (upward) approx. + 2.5 mm Thermal (downward) approx. - 2.5 mm Spoiler (aileron upward) approx. + 20 mm Flap (camber-changing flap) Horizontal transverse component (ap only upward) approx. + 10 mm Speed ight and aerobatic position (upward) approx. + 3.5 mm Thermal (downward) approx. - 3.5 mm Spoiler (aps downward) approx. -27 mm Spoiler (butterfly) / with additional transmitter - offset Both ailerons upward (20% transmitter - offset) approx. + 28 mm Both aps downward (37% transmitter - offset) approx. - 33 mm Spoiler mixing at height approx. - 3.5 mm Caution: The strength of the model is very high – but it is not comparable with full GRP-CFRP models! Speed ight and aerobatics always only in speed position of the ailerons and camber-changing aps. Do not extend the buttery at high speed – execute gliding arcs in an appropriate ratio to the speed! If you observe Building instructions

this, you will have many hours of operating pleasure with your model. For the 'spoiler' function, both ailerons are set upward and the aps downward (buttery or crow) to shorten the landing approach. At the same time, a corresponding hydroplane deection is mixed in to keep the model in a stable ying condition. This requires a remote control with corresponding mixers. To this end, always read the instructions of your remote control carefully! The buttery setting enables steep and accurate landing approaches even in difcult terrain. Hint: Depending on the terrain (e.g. tall grass), we recommend retracting the battery again shortly before making contact with the ground to ensure the hinges and linkages are not strained / damaged. Important: With the 'right' aileron, the aileron on the right looking in the direction of ight moves upward. At the same time, the right ap moves halfway up with it. With downward aileron deection, the ap does not move downward with it! If your remote control does not permit the distances specied above, you might need to adjust the pushrod connector. Make sure that all remote control components are tted correctly and connected. Check the rudder settings, directions of rotation of the servos, and freedom of movement of the rudder mechanisms. Make sure the connection cables are nowhere near the rotating motor (secure with hot glue)! Check the motor rotation direction again (carefully!).

56. Preparations for the first flight

For the rst ight wait for a day with as little breeze as possible; the evening hours often offer calmer conditions. It is essential to carry out a range-check before the rst ight! Please follow the instructions laid down by your RC system manufacturer. The transmitter battery and ight pack must be fully charged in accordance with the manufacturer’s recommendations. Before switching the system on, ensure that your chosen channel is free; this does not apply if you are using a 2.4 GHz system. If you are unsure about any point, do not y the model! If you cannot identify and cure the problem, send the whole RC system (including battery, switch harness and servos) to your system manufacturer for checking.

The aircraft is designed to be hand-launched (always into wind). If you are a beginner to model ying, we strongly recommend that you ask an experienced modeller to help you for the rst few ights. Once the model has reached a safe height, adjust the control surfaces using the trims on the transmitter, so that the model ies straight and level “hands-off”. Powered version: with the aircraft ying at an adequate altitude, check how it responds when the motor is switched off, so that you are familiar with its behaviour on the glide. Carry out repeated simulated landing approaches at a safe height, as this will prepare you for the real landing when the battery is discharged. Avoid ying tight turns at rst, especially close to the ground, and in particular during the landing approach. It is always better to land safely some distance away than to risk a crash by forcing the model back to your feet.

Making the best use of at eld thermals is not particularly easy, and calls for considerable skill and experience. Areas of rising air are harder to detect and recognise at a at eld, because they tend to occur at higher altitude than at the hillside, where it is often possible to nd lift while the model is cruising along the edge of the slope, and then circle away in it. A thermal at a at eld which occurs directly overhead is very hard to recognise, and to exploit it to the full requires a highly skilled pilot. For this reason it is always best to go thermal seeking off to one side of where you are standing. You will recognise thermal contact by the glider’s behaviour. Good thermals are obvious because the model will climb strongly, but weak thermals take a practised eye to detect, and you will need a lot of skill to make use of them. With a little practice you will be able to recognise likely trigger points for thermals in the local landscape. The ground warms up in the sun’s heat, but heat absorption varies according to the type of terrain and the angle of the sun’s rays. The air over the warmer ground becomes warmer in turn, and the mass of warm air ows along close to the ground, driven by the breeze. Strong winds usually prevent thermal build-up. Any obstruction - a shrub or tree, a fence, the edge of a wood, a hill, a passing car, even your own model on the landing ap-proach - may cause this warm air to leave the ground and rise. Imagine a drop of water on the ceiling, wandering around aimlessly, and initially staying stuck to the ceiling. If it strikes an obstruction it will fall on your head. A triggered thermal can be thought of as the opposite of the drop of water. The most obvious thermal triggers include sharply dened snow elds on mountain slopes. The air above the snow eld is cooled, and ows downhill; at the edge of the snow eld, part-way down the valley, the cool air meets warm air owing gently uphill, and pushes it up and away as if cut off by a knife. The result is an extremely powerful but bumpy thermal bubble. Your task is to locate the rising warm air and centre your model in it. You will need to control the glider constantly to keep it centred, as you can expect the most rapid climb rate in the core of the thermal. Once again, this technique does demand some skill. To avoid losing sight of the machine be sure to leave the thermal in good time. Remember that a glider is always easier to see under a cloud than against a clear blue sky. If you have to lose height in a hurry, do bear the following in mind: The structural strength of the Heron is very great for this class of model, but it is not innite. If you attempt to destroy the model forcibly, please don’t expect any sympathy or compensation from us (alas, we speak from experience).

59. Flying at the slope

Ridge soaring is an extremely attractive form of model ying. Soaring for hours on end in slope lift, without needing any outside aid for launching, must be one of the nest of modelling experiences. But to “milk” a thermal to the limits of vision, bring it down again in a continuous series of aerobatic manoeuvres, and then repeat the whole show - that must surely be the last word in model ying. Building instructions

Building instructions But take care - there are dangers for your model lurking at the slope. Firstly, in most cases landing is much more difcult than at a at eld site. It is usually necessary to land in the lee of the hill where the air is turbulent; this calls for concentration and a high-speed approach with last-minute airbrake extension. A landing on the slope face, i.e. right in the slope lift, is even more difcult. Here the trick is to approach slightly downwind, up the slope, and are at exactly the right moment, just before touch-down.

An ideal combination for learning to aero-tow, and for actual aero-towing, is a FunCub and a Heron. For the tow you require a 20 m length of braided cable of 1 to 1.5 mm Ø. Tie a loop of nylon line (0.5 mm Ø) to the glider end of the cable; this acts as a “weak link”, in case the tow should go badly wrong. A loop in the other end of the towline should be connected to the aero- tow coupling of the FunCub. Assemble the models, connect them as described, and set them up directly into wind, the glider behind the tug. Check that the towline is resting on top of the FunCub’s tailplane. The tug now rolls forward until the towline is taut, and only then should the tug’s pilot apply full-throttle. Both aeroplanes accelerate: the tug stays on the ground initially, while the glider lifts off, but the glider pilot keeps his model ying low above the ground, directly in the wake of the tug; the tug can now lift off safely. The two models should be kept climbing steadily, even through turns. Avoid ying directly over your heads during the rst few attempts at aero-towing, as it is difcult to detect the models’ attitudes from this angle. To drop the tow, operate the transmitter control which opens the tow release mechanism.

With the electric version you have the optimum level of autonomy and independence. You can y from a at eld and carry out about seven climbs to a sensible gliding height (around 150 m) from a single battery charge. At the slope you can also keep the electric power system as a “lifebelt”, i.e. you only use the motor to “keep aoat”, and avoid landing out, i.e. landing at the bottom of the slope when the lift fails.

62. Flight performance

What is meant by a glider’s performance? The two most important parameters are sinking speed and glide angle. Sinking speed is a measure of the vertical height lost per second relative to the surrounding air. The sinking speed is primarily determined by the wing loading (weight relative to wing area). Here the Heron offers a really excellent performance - much better than conventional models - as its wing loading is so low. This means that only slight thermal assistance is necessary (warm air rising) to cause the model to gain height. Wing loading is also the main factor in determining the model’s airspeed - the lower the loading, the slower the model. Low airspeed means that the model can be turned extremely tightly, and this is also advantageous when thermal ying, as areas of lift are usually very small when close to the ground. The other important parameter in glider performance is the glide angle. This is stated as a ratio, i.e. from a particular altitude the model ies such and such a distance. The glide angle increases as wing loading rises, and at the same time - of course - the model’s airspeed increases. This becomes necessary if you wish to y in relatively strong winds, and when you need “energy retention” for ying aerobatics. For thermal ying you need a good glide angle too, as this is the key to ying across areas of “sink” (the opposite of a thermal) quickly, so that you can seek out another thermal.

Safety is the First Commandment when ying any model aircraft. Third party insurance is mandatory. 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 its cover includes powered model aircraft). Make it your job to keep your models and your radio control system in perfect order at all times. Check and observe the correct charging procedure for the 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 or our website www.multiplex.de MULTIPLEX products are designed and manufactured exclusively by active modellers for practising modellers. Always y with a responsible attitude. You may think that ying 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 is in all our interests. Always y 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 ying you have under your belt, you have no idea what will happen in the next minute. Before every ight, check that the battery, the wings and the tailplane are attached and rmly seated. Check in turn that each control surface is operating correctly! We - the MULTIPLEX team - hope you have many hours of pleasure building and ying your new model. MULTIPLEX Modellsport GmbH &Co. KG
