Product description

The “Jet Gyro” electric model aircraft is a widely prefabricated RtF (Ready to Fly) model. The fuselage, the wings and tail units made of moulded foam are pre-assembled. All components required for drive and control are already built in the model and ready for use. An easy-to-use 2.4 GHz remote control is used to control the model.
The model has two electric motors, each driving its own propeller. When viewed from the rear, the right propeller rotates clockwise and the left propeller rotates counter-clockwise. The flight altitude and flight direction of the model can be controlled specifically by changing the motor speed.
In addition, the model has a built-in stabilisation system (Gyro) that detects an uncontrolled change in flight direction to the right or left and adjusts it automatically.
The model has an easy-to-attach/detach undercarriage for take-off and landing on a smooth and level surface.
The included USB charging cable is used to charge the LiPo rechargeable battery to be used in the model. The transmitter is powered by 3 AA/Mignon batteries.
Use only batteries to operate the remote control and do not use rechargeable batteries.

If you already have a policy, check with your insurance company that use of this model is covered by the policy.
Please note: In some countries, you are required to have insurance when using any model aircraft. Familiarize yourself with the local statutory regulations for using model aircrafts. In Germany, for example, the regulations for model aircraft are stipulated in the German Air Traffic Act. Any breaches of the statutory regulations could lead to severe penalties as well as restrictions to your insurance cover.

The unauthorized conversion and/or modification of the product is inadmissible due to safety and approval reasons.
This product is not a toy and is not suitable for children under 16 years of age.
The product must not get damp or wet.
If you do not have sufficient knowledge of how to operate remote-controlled models, contact an experienced model user or a model club.
Do not leave packaging material unattended, as it may become dangerous playing material for children.
If you have any questions that are not answered by these operating instructions, contact us (see section 1 for contact information) or an experienced technician.
You must first learn how to operate and handle remote-controlled models before actually using them! If you have never steered such a model, start very carefully and get used to the model’s reactions to the remote control commands first. Be patient!

b) Before operation

Select a suitable location to operate your model. Do not fly the model over people and bodies of water, or near large buildings and transmission lines.
When other models are operated in the 2.4 GHz band within the range of the remote control, check whether the transmitters operated concurrently interfere with the models.
When switching on this model, follow the procedure described below in a separate chapter. This ensures that the transmitter and receiver are connected properly and that your model responds reliably to remote control commands from your transmitter.
Conduct regular checks to verify that the model and remote control are safe to use. Inspect the parts for any visible signs of damage, such as broken connectors or damaged cables. The propellers must rotate smoothly, but there must be no play in the bearing and no out-of-true running.
The flight battery required for operation must be charged according to instructions in this manual.
Make sure the transmitter batteries have sufficient remaining capacity (battery tester). If the batteries are empty, replace all of them at the same time. Never replace individual batteries.
Check before each operation the correct and secure position of the propellers.
With running propellers, make sure that neither objects nor body parts are in the rotating and suction area of the propellers.

c) During use

Do not take any risks when using the product! Always use the model responsibly, otherwise you may endanger yourself and your surroundings.
Improper use can cause serious injury and damage to property! Ensure that you maintain a sufficient distance from people, animals and objects.
Only fly the model when you are fully alert and able to respond. Fatigue, alcohol and medication can affect your ability to respond.
Do not fly the model towards spectators or towards yourself.
Make sure the weather conditions are suitable for the model operation. Only operate the model when visibility is good. Visibility can significantly be impaired by gaining fog, low clouds or the onset of twilight. Do not operate the model in darkness, snowfall or rain.
The motors, flight controllers and flight battery can become hot during model operation. For this reason, wait 5 to 10 minutes before recharging the flight battery or restarting the model with a fully charged spare flight battery. The drive motors must be left to cool down to the ambient temperature.
Always leave the remote control (transmitter) switched on when the model is in use. After landing, always switch off the model first and only then unplug the flight battery. Only then may the transmitter be switched off.
In case of a fault or a malfunction, establish the cause of the problem before using the model again.
Do not expose the model or the remote control to direct sunlight or excessive heat for prolonged periods.

Battery information

Although batteries and rechargeable batteries are very useful in our everyday life, nevertheless they present numerous safety hazards.
Therefore, always observe the following general information and safety instructions when handling batteries and rechargeable batteries.

a) General information

Keep batteries/rechargeable batteries out of reach of children.
Do not leave batteries/rechargeable batteries lying around, as they present a choking hazard for children and pets. Seek immediate medical advice if a battery is swallowed!
Batteries/rechargeable batteries must never be short-circuited, disassembled or thrown into fire. This may cause an explosion!
When handling leaking or damaged batteries/rechargeable batteries, always use suitable protective gloves to avoid burning your skin.
Liquids leaking from batteries/rechargeable batteries are chemically highly aggressive. Objects or surfaces coming into contact with these liquids could be severely damaged. Therefore, keep batteries/ rechargeable batteries in a suitable location.
Do not attempt to recharge disposable, non-rechargeable batteries. This may cause a fire or explosion! Only charge rechargeable batteries which are intended for this purpose (1.2 V per cell); use suitable battery chargers. Non-rechargeable batteries (1.5 V per cell) are designed to be used once and must be disposed of properly when they are empty.
Please observe the correct polarity when inserting batteries or connecting the rechargeable battery pack (observe positive/+ and negative/-). Incorrect polarity will not only damage the transmitter, model and rechargeable batteries. It may also cause a fire or explosion.
Always exchange the entire set of batteries. Do not mix full batteries with half-full ones. Always use batteries of the same type and from the same manufacturer.
Never mix batteries with rechargeable batteries! Therefore only use high quality alkaline batteries for the remote control transmitter.
If you do not plan to use the model for an extended period (e.g. during storage), remove the batteries from the remote control to prevent them from leaking and causing damage. First disconnect and then remove the flight battery from the model. Store batteries and the flight battery in a dry, clean, cool place out of the reach of children. Install a smoke detector in the room. Batteries present a fire hazard and may generate toxic fumes.
This applies in particular to model batteries, which are subjected to high charging/discharge currents and vibrations.
After use, unplug the flight battery and take it out of the model. Do not leave the flight battery in the model when you are not using it (e.g. during transport or storage). Otherwise, this may cause deep discharge or permanent damage to the flight battery.
Never charge the helicopter battery immediately after use. Always allow the flight battery to cool down until it has reached room or ambient temperature again.
Only charge intact and undamaged rechargeable batteries. Do not charge the rechargeable battery if the external insulation of the rechargeable battery is damaged, or if the rechargeable battery is deformed or swollen. In this case there is serious danger of fire and explosion!
Never damage the external casing of the helicopter battery. Do not tear the film cover or prick the helicopter battery with sharp objects. This may cause a fire or explosion!
The flight battery should be placed on a non-flammable, heat-resistant surface (e.g. a stone tile) while charging. Keep the charger and drive battery away from flammable objects.
Do not charge batteries when they are still hot (e.g. due to a high discharge current in the model). Allow the battery to cool down to room temperature before charging it.
Adequate ventilation must be ensured since the charging cable and flight battery can get hot during the charging process. Never cover the charging cable and flight battery!
Never leave the flight battery of the model aircraft unattended while it is charging. Inspect the charger at regular intervals to ensure that the rechargeable battery is not overheating or expanding. This indicates an imminent risk of fire or explosion! If the battery overheats or starts to expand, disconnect it from the charger immediately and take it to a location where it will not cause any additional damage if it explodes or catches fire (e.g. outdoors).
Disconnect the charging cable from the flight battery when it is fully charged.

b) Additional information about lithium rechargeable batteries

Modern lithium rechargeable batteries are much more powerful and significantly lighter than NiMH rechargeable batteries. This makes lithium batteries (especially lithium polymer batteries) particularly suitable for use in model making. However, lithium rechargeable batteries require particular care to ensure safe charging/discharging, operation and handling. The following section provides an overview of the potential hazards associated with lithium rechargeable batteries and explains how these hazards can be avoided to ensure a long lifespan.
The casing of many lithium rechargeable batteries is made of a thick film, which is very sensitive. Do not dismantle, damage, drop or insert any objects into lithium rechargeable batteries! Do not apply mechanical loads or pull on the rechargeable battery’s connection cables. This may cause a fire or explosion! Pay attention to this when the rechargeable battery is attached to or removed from the model.
Ensure that the rechargeable battery does not overheat during use, recharging, discharging, transport or storage. Do not place the rechargeable battery near heat sources and do not expose it to direct sunlight. Overheating of the rechargeable battery may cause a fire or explosion! The temperature of the rechargeable battery must not exceed +60 °C. (If necessary follow additional manufacturer specifications for the rechargeable battery!).
Use special carry bags to carry LiPo rechargeable batteries, which can lessen the consequences of a sudden fire or explosion.
If there are any signs of damage or the outer casing starts to swell or bloat, discontinue use immediately. Do not continue to charge it. This may cause a fire or explosion! Exercise caution when handling the damaged rechargeable battery and use suitable protective gloves. Dispose of the rechargeable battery in an environmentally friendly manner.
Never store damaged rechargeable batteries in an apartment or in a house/garage. Damaged or bloated lithium rechargeable batteries can suddenly catch fire or explode.
A lithium rechargeable battery fire is difficult to extinguish and produces poisonous gases. There are commercially available special extinguishing agents for dealing with LiPo fires (fire extinguishers, extinguishing granules, etc.).
Always use a compatible charger to charge lithium rechargeable batteries and ensure that the charging method is correct. Do not use NiCd, NiMH or lead battery chargers, as these may cause a fire or explosion! Always select the correct charging method for your rechargeable battery.
When charging a rechargeable lithium battery with two or more cells, be sure to use a so-called “balancer” (the included flight battery has only one cell and requires no balancer).
The charge rate for LiPo rechargeable batteries must not exceed 1C (or the value stated in the battery instructions). This means that the charging current must not exceed the rechargeable battery capacity (e.g. battery capacity = 1000 mAh, max. charging current = 1000 mA = 1 A).
The discharge current must not exceed the value stated on the rechargeable battery. For example, if “20C” is printed on the LiPo rechargeable battery, the maximum discharging current is 20 times the battery’s capacity (e.g. battery capacity = 1000 mAh, max. discharging current = 20C = 20x 1000 mA = 20 A).
Exceeding the maximum current may cause the rechargeable battery to overheat or become deformed/ swollen, which can lead to a fire or explosion! The printed value (e.g. 20C) indicates the maximum current that the rechargeable battery can deliver for a short period. The continuous current should not be higher than one half of the stated value.
Make sure that the individual cells of a rechargeable lithium battery are not deeply discharged. This may destroy the battery or cause permanent damage.
If the model does not have deep discharge protection or a low battery indicator, stop using it before the battery becomes empty.
Commercially available LiPo checkers can be used to check the charge status of a LiPo rechargeable battery. They show the charge status of the rechargeable battery in volts or in percent. When the model is stored, the charge status of the rechargeable battery should be 35 – 40%.
Never store the rechargeable battery fully charged. This may permanently damage the rechargeable battery.

Charging the flight battery

The numbers used in these instructions refer to the illustration alongside the text or the illustrations within the respective section. Therefore, e.g. number 1 or 2 can identify different components depending on the figure. Any cross-references to other figures are indicated with the figure number and the corresponding number

The charging cable in Figure 2 is wound up for photo-technical reasons. Before the first use, open the cable tie and unwind the charging cable completely.
Connect the reverse polarity protected plug of the charging cable (1) to the connection plug (2) of the flight battery (3).
Then connect the USB plug (4) of the charging cable to a USB port of a computer/laptop or to a USB charger plug. Optionally, you can use a suitable powerful power bank.

Important!
The USB port output current must be at least 500 mA.
Do not connect the charging cable to a USB hub without a separate mains adapter (e.g. a keyboard USB port, etc.), because this will not provide sufficient current for charging.
When connecting the charging cable to the USB port of a computer, the operating system does not recognise any new hardware since this port serves only for charging.
Note that the USB ports of a computer/laptop are usually only active when the computer/laptop is turned on.
With this in mind, it is recommended that you only connect the charging cable to the computer/laptop when it is turned on.
The charging control LED (5) on the USB plug glows steadily and thus signals the ongoing charging process.
When charging is complete and the flight battery is fully charged, the red LED of the USB plug goes out.
The flight battery may take up to an hour to charge depending on its charge status and current strength of the USB port.
Disconnect the charging cable from the flight battery immediately after charging and unplug the USB plug of the charging cable from the computer/laptop or charger plug.

Important!
Only use the included charging cable to charge the helicopter battery. Never attempt to charge the rechargeable battery with a different/incompatible charger! Only charge the helicopter battery when you are able to monitor the charging process.

Final assembly of the model aircraft

Before starting with the assembly of the model, prepare an appropriate surface. In order to achieve excellent flight performance, your model is manufactured with a light moulded foam. This material has a sensitive surface. Even minor carelessness during assembly of the model may very quickly result in ugly dents or scratches.

Mounting the tail fins
Place the tail fins (1) on the guide rails so that the two hooks (2) engage in the openings (3).
Then push each tail unit forward in the direction of flight so that the locking latches on the hooks lock the tail unit in place.
Then check the alignment of the tail fins. There should be the same distance between the tips of the tail fins and the tail plane (sections A1 and A2).

Mounting the undercarriage
The model can be equipped with a nose undercarriage (1) and a main undercarriage (2) for take-off and landing on a smooth and level surface. For this purpose, the undercarriage wires are inserted into the prepared undercarriage mounts (3) on the underside of the fuselage.
Since the undercarriage wires are held in place by spring force, no extra securing is required. In addition, the undercarriage can be easily attached and detached at all times.
It is advisable not to use the undercarriage when operating the model on a lawn or meadow. In this case, the model is launched by hand and belly landed on the grass.

Inserting and connecting the flight battery
The flight battery slot is located on the underside of the fuselage directly behind the nose undercarriage slot (see also Figure 4, no. 4).
Push the locking lever (1) forward and swing open the cover (2).
Before connecting the flight battery (3), check the on/off switch on the receiver (4). The switch must be in the “OFF” (= switched off) position, as shown in Figure 5.
Connect the reverse polarity protected plug of the model electronics (5) to the flight battery.
Try to arrange the flight battery as close to the front of the slot as possible. If necessary, use a small piece of foam to fix the flight battery in this position and close the cover. The cover lock must securely snap into place.

Caution, important!
When the model is not in use, for example, when it is transported or stored, always unplug the flight battery and remove it from the slot. The flight battery should only be connected when you are using the model.

Transmitter controls

Joystick for the drive motors
LED indicator
Direction control joystick
On/off switch

Unlike the direction control joystick (3), which is held in the middle position by spring force, the joystick for the drive motors (1) always remains in the last set position. In addition, this joystick has a very fine pitch that can be felt when it is moved forwards and backwards.

Using the transmitter

Inserting the batteries
The transmitter is powered by 3 Mignon/AA batteries.
Use only batteries (1.5 V/cell) and do not use rechargeable batteries (1.2 V/cell) as the power supply for the transmitter.
To insert the batteries, proceed as follows:
Loosen the retaining screw (1) on the battery compartment cover (2) on the back of the transmitter with a suitable screwdriver.
Push down the locking latch (3) of the cover lock to the side and lift off the battery compartment cover.
Insert 3 Mignon/AA batteries according to specifications on the bottom of the battery compartment (4), observing the correct polarity. The spiral spring contact (5) must always be connected to the negative pole of the battery.
Replace the battery compartment cover and allow the locking mechanism to lock into place in the transmitter housing.
Then tighten the retaining screw.

Switching on the transmitter
Check the correct power supply of the transmitter by putting it into brief operation for test purposes.

Caution, important!
Before switching on the transmitter, make sure that the joystick for the drive motors (1) is in the rear position (lower position in the figure).
When you press the on/off switch (4), the transmitter LED (2) starts to flash.
Now push the joystick for the drive motors all the way forward (up) and back to the rear (lower) position. The transmitter LED will now glow steadily. To switch off the transmitter again, press the on/off switch again.
When the power supply is not enough to ensure proper operation of the transmitter, the transmitter LED starts to flash.
In this case, discontinue using the model aircraft and replace the old batteries in the transmitter with new fresh ones.

Steering the model aircraft

Before operating the model for the first time, it is necessary and important that you familiarise yourself with the basic control functions.
Once switched on, use the two joysticks on the transmitter to control the model. Use the joystick for the drive motors (see Figure 6, no. 1) to adjust the common speed of the two electric motors. The farther the joystick is pushed forward, the higher the speed of both motors and thus the thrust of the model.

At maximum speed, the model ascends upwards at an increasingly steeper angle (see Figure 10, item A).
At reduced speed, the model remains at a constant altitude (see Figure 10, item B).
At lower speeds, the model reduces the flight altitude (see Figure 10, item C).

Use the right joystick to control the flight direction (see also Figure 6, no. 3).
When the direction control joystick is not used, it remains in the middle position by spring force. Both motors run at the same speed when throttling and the model flies straight ahead (see Figure 9).
When pushing the direction control joystick to the left as the model flies straight ahead, the right drive motor speeds up while the left drive motor slows down. The model enters the left turn due to different thrust forces (see Figure 11).

When pushing the joystick to the right, the left drive motor speeds up while the right drive motor slows down. The model enters the right turn (see Figure 12).

Caution, important!
Briefly pushing the direction control joystick changes the flight direction only slightly. It may be necessary to carry out several brief pushes of the joystick in order to change the flight direction. Prolonged deflection of the joystick or maintaining the deflected position of the joystick for too long may result in the model descending steeply in a spiral and incurring damage.
The model shows a much more stable flight behavior when flown against the wind versus with a tailwind. Thus, the direction control joystick needs to be deflected more often and more strongly so that the model performs the desired curve.

Commissioning the model aircraft

The model is controlled using a 2.4 GHz remote control. The receiver should be electronically connected to the transmitter for the model to respond to the control commands from the transmitter. This connection is established when the transmitter is switched on. It is therefore essential that you follow the power-on procedure listed below.

Switching on the model aircraft
Fully charge the flight battery and insert it into the model according to the procedure described in section 9.
Slide the on/off switch on the model (see also Figure 5, no. 4) to the “ON” position (= switched on). The LED on the receiver electronics (1) starts to flash quickly. Then position the model horizontally on a level surface.
Before switching on the transmitter, push the joystick for the drive motors (see also Figure 6, no. 1) to the rear position (motor off). Then use the on/off switch (see also Figure 6, no. 4) to switch on the transmitter. The transmitter LED starts to flash. The LED on the receiver electronics lights up briefly and then starts to flash slowly.
To activate the motor control, push the joystick for the drive motors all the way forward and then immediately back to the rearmost position.
The LEDs on the transmitter and receiver electronics will now glow steadily. The model is now ready for take-off.

Checking the control functions
Before checking the control functions of the model, make sure that the rotating and suction area of the propellers is free from loose objects, body parts or hair. Have an assistant hold the model firmly so that it cannot roll away during the motor check. The thrust produced by the running propeller can very easily blow small and light objects, such as spare propellers, off the table.
Slowly push the joystick for the drive motors forward. The motors must start and speed up or slow down depending on the position of the joystick.
When the right joystick is deflected to the left, the right motor must speed up and the left motor audibly slow down (see also Figure 11). When the right joystick is pushed to the right, the motors must behave the other way around (see also Figure 12). Much noise is produced when changing speeds.

The direction control can also be checked when the joystick for the drive motors is in the lowest position.

Checking the Gyro function
The model is equipped with a position sensor that detects whether a change in direction has been transmitter controlled or not. When deflection of the model occurs e.g. due to a gust of wind, the stabilisation system (Gyro) detects the uncontrolled deflection of the model and automatically counteracts it. To check the function of the stabilisation system, hold the model with your hand from below and let the motors run at approx. 30 – 50% power. The direction control joystick must be in the middle position and must not be manipulated during the Gyro test.
When turning the model around the vertical axis to the left at this point, the left propeller must speed up (H) and the right propeller slow down (L). When turning the model to the right, the right propeller must speed up (H) and the left propeller slow down (L) (see Figure 14). Even now the changing motor speeds can be heard very clearly.

First flight

Prior to your first flight, you must charge the flight battery according to the instructions in the chapter “Charging the flight battery”. You can test the remaining capacity of the transmitter batteries with a battery tester.
Once you have again briefly checked the function of the motors, your model is ready for its first flight.
Look for a suitable flying location that offers enough space and is not obstructed with obstacles. Wait for a slightly windy day or a day without any wind.

Range test
First carry out a range test of the remote control on the flying site. First start the transmitter and then the model. Ask an assistant to hold the model and check the range by moving slowly away from the model aircraft. The control functions should work smoothly within a range of 80 – 100 m.

Take-off
Manual launch:
It is generally possible to start the model alone without any real problems. However, we recommend taking an assistant along for your first flight who can hold the model while it is started. This leaves both your hands free for controlling and fully concentrating on the model. When launched by hand, the model already has a certain distance to the ground so that a slight sagging after the take-off is not a problem. The assistant should grab the model from below the wing on the fuselage with their thumb and forefinger.

Our tip:
In order to be able to identify the flight attitude of your model, you should stand at a little distance behind your assistant and look exactly in the flying direction of the launched model.

Warning!
You must launch the model against the wind in all cases! Even if it blows very weakly.
Now throttle gently and allow the motors to run at approx. 50% power. The assistant should strongly push the model forward to accelerate it and release it. The tip of the fuselage of the model must always point slightly upwards and the wings must be aligned horizontally.

Ground launch:
If a flat, smooth and sufficiently large surface is available, the model can also be launched from the ground. Orient the model at the launch point so that it points towards the wind with the fuselage tip and stand behind the model. Accelerate quickly and make sure that the model does not break out sideways. The roll direction can easily be adjusted with the direction control joystick. After a short roll, the model will automatically lift off the ground.
If the battery is fully charged and started correctly, the model will rise at a shallow angle. Try to minimise control for a moment so that the model gains altitude as it flies straight ahead. However, if the model brings the tip of the fuselage steeply upwards, reduce the motor power gradually.
If the model lowers the tip of the fuselage, increase the motor power gradually. Rely heavily on your intuition when steering. The pitch of the joystick is very useful.
Let the model gain a sufficient altitude before carrying out the first turn. Do not fly too high and not too far away so you can always check the flight position of your model. Once you have reached the desired height, reduce the motor speed so your model can fly at a constant altitude.

Should the model fly beyond the effective range of the remote control, the motors will turn off automatically. The model will then glide to the ground without propulsion.

Turning flight
Push the direction control joystick (see also Figure 6, no. 3) to the right or left until the model assumes the desired flight direction. Begin with light and brief control manipulations and observe the model behaviour. The longer and farther you push the joystick, the tighter and steeper the turns become. At the beginning, try to fly large and wide circles. Once the model flies in the desired direction, move the joystick back to the centre position.
When performing a turn, always pay attention to the altitude. If the model loses altitude, increase the motor power for the model to ascend again.

Important!
If the model no longer gains altitude at maximum motor power, the flight battery is almost empty. In this case, land the model immediately to prevent deep discharge and damage to the flight battery.

Landing
As with the take-off, the landing must always take place against the wind. Reduce the motor performance and fly in big flat circles to slowly reduce the altitude.
Select the last curve before the approach for a landing so that in case of an emergency you would have sufficient room for landing and so that you would not have to effect considerable corrections to the course during the approach for a landing. As the model flies toward the planned touchdown point, reduce the motor speed so that it descends continuously and flies toward the planned touchdown point.
If the model loses altitude too quickly, add a little motor power until it flies back toward the planned landing point. Only turn off the motors completely right before touchdown.

Trimming the model aircraft
Use the trimming function if the model fails to fly straight ahead with reduced motor power or tends to automatically roll around its longitudinal axis or fly curves. Since the EPP moulded foam is tough and malleable, you can easily deform the tail units and wings with little effort.
If you look at your model from behind from some distance, you will immediately notice if the wings or tail units are crooked or warped. Once carefully deformed in the opposite direction, the material no longer readily goes back all the way to its original position. There is a certain desirable residual deformation. If necessary, carry out several deformation manipulations until the model flies straight ahead.
Elevator trim
If the model tends constantly to ascend, you can bend the trailing edges of the two tail planes downwards and the leading edges upwards to trigger an elevation rudder effect on the tail plane.

If the model tends constantly to lower the tip of the fuselage, move the flight battery to the rearmost position in the slot.
As a second step, you can bend the trailing edges of the two tail planes upwards and the leading edges downwards to trigger an elevator effect on the tail plane.

Rudder trim
If the model constantly performs a left turn, bend the trailing edges of the tail units to the right and the leading edges to the left. The deformation triggers a rudder effect to the right on the tail fin.

If the model constantly performs a right turn, bend the trailing edges of the tail units to the left and the leading edges to the right. The deformation triggers a rudder effect to the left on the tail fin.

Aileron trim
If the model constantly rolls to the left about its longitudinal axis, bend the trailing edge of the right wing up and the trailing edge of the left wing down. The deformation triggers an aileron effect to the right on the wings.

If the model constantly rolls to the right about its longitudinal axis, bend the trailing edge of the right wing down and the trailing edge of the left wing up. The deformation triggers an aileron effect to the left on the wings.

Maintenance and cleaning

Check the proper functioning of the remote control as well as the smooth running of the motors on your model at regular intervals. If necessary, apply a small drop of mineral oil on the rear motor bearings.
The motors should turn easily by hand and the propeller should not be damaged or torn. Replace the propeller with the included spare propeller or order an original spare propeller.
Clean the exterior of the model and the remote control only with a soft, dry cloth or brush. Never use aggressive cleaning chemicals or detergents, as these may damage the surface of the boat.

Important!
If you have to replace damaged or worn parts, only use original replacement parts. The spare parts list can be found on our website in the download area for the respective product.
If moulded foam parts have to be glued to the model aircraft, only use adhesives that are suitable for Styropor®.

Replacing the propellers
The propellers (1) are only attached to the motor shafts (2). Use a small flat screwdriver or tweezers to pull off the defective propeller.

Important!
When mounting the new propeller, always pay attention to the direction of rotation of the motor.
When viewed in the direction of flight, the left motor has the code letter “A” and turns the propeller counter-clockwise.
The right motor has the code letter “B” and turns the propeller clockwise.
The matching propellers also bear the code letters “A” or “B”.
The propellers must be mounted on the shaft such that the side with the inscription (3) is facing backward.
