Instruction Manual

Safety information for MULTIPLEX airplane models

When operating the model, all warning and safety information in the operating instructions must be observed.
The model is NOT A TOY in the conventional sense. If you use your model carefully, it will provide you and your spectators with lots of fun without posing any danger. If you do not operate your model responsibly, this may lead to significant property damage and severe injury. You and you alone are responsible for following the operating instructions and for ensuring the safety guidelines are adhered to.
When setting up the model, operators declare they are familiar with and understand the contents of the operating instructions, particularly regarding safety information, maintenance work, operating restrictions, and deficiencies.
This model may not be operated by children under the age of 14. If minors operate the model under the supervision of a responsible and competent adult pursuant to the law, this person is responsible for adhering to the information in the operating instructions.
THE MODEL AND THE ASSOCIATED ACCESSORIES MUST BE KEPT OUT OF REACH OF CHILDREN UNDER 3 YEARS OF AGE! CHILDREN UNDER 3
COULD SWALLOW REMOVABLE SMALL PARTS OF THE MODEL. RISK OF SUFFOCATION!
Multiplex Modellsport GmbH & Co. KG is not liable for loss, damage and consequential damage of any kind caused by incorrect operation, improper use or misuse of this product, including the accessories used along with it.
Proper use
The model may only be used in the hobby sector. No other type of use is permitted. To operate the model, only the accessories recommended by Multiplex may be used. The recommended components have been tested and adjusted for safe functioning together with the model. If other components are used or the model is modified, all claims against the manufacturer or retailer are void.
In order to minimize the risk when operating the model, observe the following points in particular:

• The model is controlled via 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, the 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 flown in good visibility. Do not fly in poor light or in the direction of the sun in order to avoid glare.
• The model may not be operated under the influence of alcohol or other intoxicants. The same applies for medicines that impair perception and responsiveness.
• Only fly 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 fly 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 fly in a manner that ensures neither you nor others are exposed to danger – even many years of accident-free flying experience are no guarantee for the next minute of flying 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.
Insure 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 fly in a safe environment and at an authorized model airplane flying fields.
• Crashes caused by technical failures, undetected damage from transportation or pre-existing damage: The model must be carefully inspected before each flight. 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 flying 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 flights.
• Risk of fire 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.

The electronics must be protected from water. The controller and the batteries must be sufficiently cooled.

Safety information for MULTIPLEX construction kits

Familiarize yourself with the construction kit!
MULTIPLEX model kits are subjected to constant material inspection during production. We hope that you are satisfied 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 fix or replace it after verifying this. Please send the part with sufficient 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 specifications and illustrations in these instructions.
Caution!
Remote-controlled models, particularly airplane models, are not toys in the conventional sense. Their construction and operation require 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.
Warning:
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 fitted with the propeller recommended by us but can only withstand the loads if it is built flawlessly and is undamaged.
Crooked – does not really exist. If individual parts are bent during transit, they can be straightened again. Here, ELAPOR® behaves like a 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’s paints results 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 superficially 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 fingers 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 especially 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 significantly weakened. Especially for large-scale adhesion, we recommend allowing 24 hours for the parts to dry.
• Activators must only be used for point fixing. Only spray a little activator on one side. Allow the activator to flash off for approx. 30 seconds.
• For optimal bonding, sand down the surface using sandpaper (grain size 320).

Specifications

Assembly instructions

Before assembly
Use the list of components and Fig. 1 to check the completeness of the components supplied.
We recommend using a soft, clean, and flat surface to ensure the model is not damaged during assembly. Always use, unless otherwise specifically stated, ZACKI ® -ELAPOR instant adhesive for gluing.
1. Completing the wings
Place the upper wing 2 as shown in Fig. 2 on a clean and flat surface to ensure it is not damaged. Experimentally insert canopy 4 into the pockets of the wing. This should be possible without having to apply too much pressure. If this is not the case, minor adjustments to the recesses for the carbon fiber spars may be necessary. It is essential that the canopy can be glued into the pockets fully and flush with the surface, otherwise the correct installation angle difference will not be set. After making sure everything fits properly, slightly roughen the contact surfaces with sandpaper (240-320 grit), preferably also the exposed piece of the carbon fiber spar. Now apply sufficient adhesive to the contact surfaces and insert the canopy firmly. Use a paper towel to wipe off any escaping adhesive. Weigh down the canopy, e.g. with the flight battery, until the adhesive has set fully. The bonded joint is very important and must, therefore, be carried out carefully.
While the upper wing is setting, glue the wing struts 5 and 6 onto the lower wing 3. Fig. 3 shows the installation direction, the procedure is exactly the same as for the canopy; also ensure the bonded joint is sufficiently secure. When both components have been set sufficiently, join them together. Place the upper wing as shown in Fig. 4 on the surface
and perform all the work steps as usual. Make sure the components are aligned properly to each other.
2. Gluing in the tailplane
In the next work step, tailplane 7 is glued to fuselage 1; to do so, please refer to Fig. 5 . The process is the same as before; fit together without adhesive, roughen slightly, clean, apply ZACKI ® , fit together, align properly. To check everything is correct, as shown in Fig. 6 , measure the distance from the wing tips of the tailplane to the recess of
the lower wing. The distance should be the same on both sides and the tail should sit horizontally on the fuselage Fig. 17 .
3. Gluing in the vertical tail
The procedure for gluing in the vertical tail is shown in Fig. 7 . Here, too, the respective work steps must be carried out carefully. During the trial fitting, the rear undercarriage can be experimentally pushed through the hinge. It is now possible to carry out any reworking that might be required. When gluing the tail, the rear undercarriage can be inserted as a positioning aid. Take special care that ZACKI ® does not come into contact with the hinge. Use Fig. 17 to check the correct alignment of the tail to the fuselage.
4. Installing the RC
Install the receiver in the model. To do so, use a piece of the supplied hook and loop tape ⓰. Ideally, the hook side is glued into the fuselage and the loop side onto the receiver. The servos can now be connected. The numbering facilitates assignment. In the next step, make sure your transmitter is ready for operation. This involves assigning the channels correctly and ensuring the trim is set to neutral. Now insert the battery using a piece of hook and loop tape ⓰ Fig. 11 . It is now time to bind your receiver. The servos can now be controlled and should be set to neutral. Make sure the rods do not come into contact with anything, thereby blocking the servos. As this could damage the servos.
5. Assembling the wings
As shown in Fig. 8 , insert the fuselage between the wings until the canopy is aligned with the provided recess. Now push the wing unit sideways onto the fuselage and fix it into position with the screws ⓭ and ⓮.
6. Assembling the undercarriage
Insert the pre-assembled rear undercarriage ⓾, as shown in Fig. 9 , through the rudder hinge and tighten both screws ⓯ with a cross-tip screwdriver (size PH0). The main undercarriage is inserted beneath the heads of the nylon screws at the front and clipped into the closure at the rear. To do so, please refer to Fig. 10 . Now tighten the screws slightly. When disassembling, loosen the screws slightly (they do not always have to be unscrewed fully) and release the closure at the rear. The undercarriage can now be removed.
7. Establishing the aileron linkages
The elevator linkage is shown in Fig. 12 . Unscrew the grub screw of the pushrod connector (using the enclosed hex wrench ⓱) as far as necessary to guide the end of the pushrod through the hole. Arrange the elevator in a line with the tailplane fin. A ruler or set square is a great help when doing this. Fig. 13 shows connection of the rudder. The same applies here as with the elevator.
Insert the aileron pushrods as shown in Fig. 14 . Initially set the lower aileron flush with the wing. Subsequently, thread the aileron connector ⓲ through the pushrod connectors and tighten the grub screw on the lower one. The upper aileron can now be adjusted. Subsequently, carry out the same procedure on the other side until all the rudders have been linked. Now it is time to adjust the deflection sizes. Please adjust them for the initial flight according to our recommendations.

• Elevator +25 mm/-25 mm 30%Expo
• Rudder +30 mm/-30 mm 20%Expo
• Aileron +15 mm/-14 mm 30%Expo (measured on the lower wing)

8. Installing the propeller and the spinner
Seeing as the motor screws are still freely accessible, make sure they have been tightened correctly. Although this is actually part of the preflight check, it is no longer possible once the propeller and the spinner have been installed. The propeller is installed on the motor shaft as shown in Fig. 15 . We recommend balancing the propeller with our propeller balancer # 332355 prior to assembly. Tighten the propeller nut firmly. The spinner is simply attached to the spinner driver from the front. Now check the gap between the fuselage and the spinner by turning the propeller manually. The spinner must not come into contact with the fuselage and should run smoothly. Please disconnect the battery beforehand to ensure your safety!
9. Adjusting the center of gravity
The center of gravity can be adjusted by moving the drive battery. This procedure should be done carefully as it is crucial for the subsequent flight characteristics of the model. The position of the center of gravity is 13 mm in front of the carbon fiber spar of the upper wing. Support it with your fingertips. Now move the battery until the nose of the model points downward slightly as shown in Fig. 16 . Once set up like this, you can calmly proceed to the initial flight.
10. Preflight check
However, before the initial flight, always carry out a preflight check.

• Check all the screws, including the grub screws, and retighten them, if necessary
• Check the rods, they should never come into contact with other parts
• Undercarriage properly engaged
• Use Fig. 17 to check the symmetry of the model
• When checking the rudder, also check the directions of rotation and resets
• Caution: Do not connect the battery until the transmitter is switched on and the operating element for the motor control is set to “Off”.
• Make sure the motor is running correctly (unbalance) and check the motor rotation direction
• Perform a range of test

11. Initial flight
If your model is in perfect working order, the weather conditions are suitable and your transmitter and drive batteries are fully charged, you can finally get started.
Position TOMMY jr. with its nose facing the wind and accelerate slowly. After rolling a short distance, it will take off. Once it has climbed to a safe altitude, you can test the rudder reactions and slow flight characteristics. During the initial flight, always remember to land in good time to avoid any unnecessary stress caused by the motor being cut off by the voltage protection. Gradually adjust the rudder deflections and the center of gravity as desired during subsequent flights. We hope you enjoy your TOMMY jr. and wish you lots of fun flying it.
