• 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 responses to the remote control commands first. Be patient!

b) Charger

• The design of the battery charger conforms to protection class II. The charger must be connected to a properly grounded mains socket of the public supply grid (for charger operating voltage, see section “Technical data”).

• The mains socket the charger is plugged into via the power cord must be easily accessible.

• The charger is only suitable for charging 2- or 3-cell LiPo rechargeable batteries. Never use the charger for any other purpose. Never use the charger to charge NiMH rechargeable batteries (or rechargeable batteries other than 2- or 3-cell LiPo ones) to avoid the risk of fire and explosion!

• Only insert a single LiPo rechargeable battery into the charger (the two outputs must never be used at the same time).

• The charger has XH sockets for connecting the LiPo rechargeable battery. The rechargeable battery must also have a corresponding XH connector, otherwise matching adapters are required. Always pay attention to the correct pin assignment.

• Never short-circuit the charger outputs and never connect the outputs together.

• The charger may only be used in dry, enclosed spaces. It must be protected from moisture and dampness; never touch it with wet hands to avoid the risk of death from an electric shock! The same applies to the power cord and mains plug.

• Do not pull the mains plug out of the mains socket by the cable. Grasp the plug by the side of the housing and pull it out of the main socket.

• If the charger and/or the power cord show signs of damage, do not touch it to avoid the risk of death from an electric shock! First switch off the mains voltage for the mains socket the charger is plugged into (switch off the associated circuit breaker or unscrew the fuse, then switch off the ground fault circuit interrupter so that the mains socket is completely disconnected from the mains voltage). You can then unplug the power cord from the main socket.
  Dispose of the damaged charger/power cord in an environmentally friendly manner and do not use it anymore. Make sure you use a structurally identical charger/power cord instead. A defective power cord must never be repaired!

• Mains-operated devices should not be used by children. Therefore, be especially careful when children are around. When using the charger, always make sure that children cannot reach it.

• Avoid the following unfavorable environmental conditions at the place of use, and during transportation:
  – Wetness or high humidity
  – Cold or heat, direct sunlight
  – Dust or flammable gases, fumes, or solvents
  – Strong vibrations, impacts, or blows
  – Strong magnetic fields, such as those found close to machinery or speakers

• Never use the charger/power cord immediately after it has been brought from a cold room to a warm one. Otherwise, this may result in the formation of condensate, which can destroy the charger under certain circumstances. There is also a risk of death from an electric shock! Allow the product to reach room temperature before connecting it and putting it into use. This may take several hours.

• Make sure that the charger power cord is not kinked or crushed. The same applies to the cables of the LiPo rechargeable battery.

• Handle the product with care, because it can be damaged by jolts, impacts, or a fall from a low height.

c) Before operation

• Select a suitable location to operate your model.
• Ensure that there are no other models operating at the same transmission frequency (2.4 GHz) within range of the remote control. Always check whether there are any other 2.4 GHz remote controls that may interfere with the model.
• When switching on this model, follow the procedure described below in a separate section. 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 propeller must turn smoothly, but there must be no play in the bearing and no out-of-true running. The rudder flaps and the associated linkages must be easy to move and must function accurately.
• Charge the flight battery, which is necessary for operation, as well as the rechargeable battery needed in the remote control transmitter according to the instructions indicated by the manufacturer.
• Before using the remote control, use a battery tester to check that the batteries have sufficient remaining power. If the batteries are empty, replace all of them at the same time. Never replace individual batteries.
• Before each operation, check the settings of the trim buttons on the transmitter for the different steering directions and, if necessary, adjust them.
• Before operating the model aircraft, always check the propeller for proper fit and firm seat as well as the functionality and running direction of the rudder flaps.
• Make sure that the rotating and suction area of the propeller is kept clear of any objects or body parts while it is turning.

d) 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 toward 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.
• The motor, flight controller, and flight battery can heat up during the operation of the model. Therefore, take a break of 5-10 minutes before re-charging the flight battery or before re-starting with a spare flight battery, if any. Allow the motor to cool down to room temperature.
• Always keep the remote control (transmitter) turned on when the model is in use. Always unplug the flight battery in the model after landing. 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 that are intended for this purpose (1.2 V); use suitable battery chargers. Batteries (1.5 V) 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!

• Place the charger and flight battery on a non-flammable, heat-resistant surface (such as a stone tile). Keep them away from flammable objects. Ensure sufficient space between the charger and the flight battery; do not place the flight battery on or near the charger.

• Do not charge rechargeable 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.

• Ensure that there is sufficient ventilation, as the flight battery and charger may heat up during the charging process. Never cover the charger or the quadcopter 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 flight battery from the charger 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 rechargeable batteries (especially lithium polymer batteries) particularly suitable for use in model making.
However, lithium rechargeable batteries require particular care t o 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 next to sources of heat (e.g. a speed controller or motor) or 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, extin- guishing 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.
  • Always use a so-called balancer when charging a lithium rechargeable battery with more than one cell (the charger comes with a built-in 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 2-cell lithium polymer flight battery is charged using the included charger via the balancer connector. It is essential that you also observe section 7 of these operating instructions.

Important:
The flight battery must not be connected to the model aircraft’s flight controller while it is charging. This can damage the flight controller and interrupt the charging process!

The charging process takes place by connecting the XH plug (1) of the balancer connection cable (2) of the flight battery (3) to the left charging socket of the charger (4). The two locking lugs of the XH plug must point upwards. Connect the power cord (5) to the charger and insert the Euro plug of the power cord into a proper mains socket of the public supply grid. The two charge control LEDs (6) marked CELL1 and CELL2 light up red and show the charge status of each of the two cells during the charging process. The third LED (7) marked CELL3 glows green steadily, as the flight battery only has two cells and is connected to the charging socket for two-cell rechargeable batteries. As soon as the battery cell is fully charged, the LED of the charged cell changes from red to green. When the charge control LEDs of cells 1 and 2 light up green, this means that the flight battery is fully charged. Then disconnect the rechargeable battery from the charger and unplug the charger from the mains socket.

It can take up to 2 hours to charge the flight battery depending on its charge status.
During the flight, the model is powered via the two-pole cable with the XT60 connector (see Figure 2, no. 8).

The LiPo flight battery can also be charged with another matching LiPo charger. However, it must have a balancer for monitoring and, if necessary, adjustment of the voltages of individual cells. Observe the operating instructions for the LiPo charger used. If in doubt, only use the included charger.
Warning!
Only use a matching LiPo charger to charge the LiPo flight battery. Never attempt to charge the LiPo flight battery with a different or non-matching charger! This may cause a fire or explosion! Only charge the flight battery when you are able to monitor the charging process.

Construction 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 light plastic foam. However, this material has a sensitive surface. Even minor carelessness during assembly and later during the operation of the model may very quickly result in ugly dents, scratches, or other surface damage.
Therefore, proceed carefully.

a) Removing and installing the canopy
The canopy is held in place with a pin at the front and a magnet at the back.
To remove the canopy, lift it at the back and pull it up and away.
To put the canopy on, first, guide the canopy pin under the fuselage at the front and then place the canopy onto the magnet at the back.

b) Mounting the tailplane
The tailplane of the model aircraft can be folded up using a remote control command to enable vertical landing. For this reason, it is essential to ensure that the locking mechanism works smoothly when installing the tailplane. Place the tailplane (1) on the tail of the fuselage as shown in the upper picture in Figure 3.
Push the release lever (2) into the tail of the fuselage so that the locking pin (3) can easily reach the hole in the tailplane bracket (4).
Then carefully screw the tailplane tight to the fuselage with a 2.6 x 10 mm screw (5). Do not apply too much force to avoid damaging the screw or the screw socket.
Then check whether the tailplane lock can be opened and closed smoothly. To do this, simply push the release lever carefully into the fuselage.

Attach the two tension springs (6) as shown in the upper picture in Figure 4.
Make sure that the connection cable of the elevator servo (7) does not impair the function of the springs and that it cannot be damaged. Connect the elevator servo connector (8) to the supply cable connector (9). When connecting, ensure that the plug connectors are correctly aligned.
The cables must be connected as follows:

• White and orange
• Red and red
• Black and brown

The connector is to be stowed in the tail of the fuselage (see the following section).

c) Mounting the tail fin
Before you can insert the tail fin (1) into the dedicated slot(2) at the tail of the fuselage, you must first lay the elevator servo cable (3) sideways in the shaft.
Ensure the cable is not pinched under the tail fin, or you will not be able to correctly fit the fastening screw.
Then put on the tail fin and screw it tight from below using the 2.6 x 14 mm screw (4).

d) Mounting the wing
Before you can mount the wing on the fuselage, you must first make electrical connections.
To do this, push the connection cable (1) of the aileron servo through the fuselage opening near the wing saddle and into the cockpit area.
Then connect the three motor connection wires (2) with the three wires that come from the flight controller.
There is no special polarity that must be considered when connecting the motor. Connect the aileron servo plug (3) to the free receiver output channel

1. Pay attention to the polarity and follow the cables of the already connected plugs.
   Before proceeding to the next assembly step, be sure to check the direction of rotation of the motor and the alignment of the ailerons.
   To do this, switch on the transmitter and set the trim to the middle position for each control channel. The necessary measures are described in detail in sections 10 and 11.
   Push the motor function joystick into the lower position and connect the charged flight battery (see Figure 7, no. 5).
   The flight controller emits four beeps via the motor. Slowly pushing the motor function joystick upwards starts the motor. Then push the joystick back to the lowest position at once and pay attention to the direction of rotation of the motor.
   If the motor turns clockwise when viewed from the rear, it is connected correctly. If the motor turns counter-clockwise, reconnect any two motor plugs to the flight controller by swapping them. Then check whether the direction of rotation has changed and whether the motor is now turning clockwise.

Then check the positions of the two ailerons. To do this, check the aileron servo lever. It should be approx. at a 90° angle to the linkage rods (see the dashed line in the upper picture in Figure 6). The trailing edges of the ailerons must then form a line (6) with the trailing edges of the wing. If there are any deviations, loosen the clamping screws (7) and readjust the ailerons. Then carefully tighten the clamping screws.
Also simultaneously check the fastening nuts (8) of the screw nipples. The nipples must be able to turn, but not wobble.
Following adjustment, unplug the flight battery and then switch off the remote control transmitter. Now you can set the wing onto the fuselage.
Make sure that no cables are pinched between the wing and the fuselage.
Fasten the wing at the front using the M3 x 25 mm screw and at the back using the two M3 x 20 mm screws. Use the included hex key (9) to tighten the screws.

e) Checking the tail unit alignment
With the wings in place, you can easily check the orientation of the tail units. To do this, look at your model from behind from a little distance. The tail plane and tail fin must be aligned at a 90° angle to each other. In addition, the tailplane must run parallel to the wing (see Figure 10, sketch A).
An inclined position of the tail fin (see Figure 10, sketch B) or the tailplane (see Figure 10, sketch C) can be corrected by inserting or underlying thin cardboard strips.

f) Mounting the receiver and the flight controller
It is recommended that the double-sided adhesive tape be used to attach the receiver (1) to the inside of the fuselage side wall.
The antenna (2) is guided to the outside through a small opening made with the help of a thin wire.
Important!
Do not guide the antenna in the fuselage. The current-carrying wires can cause radio shadows and thus disturb signal transmission.
The flight controller (3) is attached to the battery board with double-sided adhesive tape and additionally secured with the hook and loop fastener (4).

g) Installation of the propeller
The propeller driver must be disassembled before installing the propeller. Use the clamping pin (1) and the clamping ring (2) to clamp the motor shaft.
To center the propeller (3), insert an adapter ring (4) with an inner diameter of 5 mm and an outer diameter of 8 mm into it. Initially, screw the spinner cap (5) loosely.
Caution is important!
Make sure that the propeller is correctly aligned! The more curved edges of the propeller blades must point forwards in the direction of flight, i.e. towards the clamping ring (see illustration of the fully assembled propeller/driver unit).
Then put the propeller/driver unit onto the motor shaft and carefully tighten the unit using the hex key (6).

h) Inserting the flight battery
Attach the fleece part of the hook and loop fastener to the flight battery to prevent it from slipping during operation. The hook part of the hook and loop fastener must be attached to the battery board.
Then attach the battery with the fleece part to the hook part and secure it with the hook and loop fastener.
The exact position of the battery is specified in the following section.

Important!
Always ensure that the flight battery is correctly attached. Shifting of the battery in flight can change the model’s center of gravity.
This can in turn worsen the flight characteristics to the extent that will render the model uncontrollable in the air.

i) Checking and adjusting the center of gravity
After the flight battery is installed, make sure you check the center of gravity. To do this, put on the canopy. The center of gravity is 42 mm behind the leading edge. If
the model is supported at this point, it must be balanced horizontally.
The model structure enables precise adjustment of the center of gravity by moving the flight battery.
If the battery cannot be moved any further, you can also use commercially available small rim weights to adjust the center of gravity, if necessary.

Our tip from experience:
Attach two narrow strips of insulating tape to the bottom of the wing on the right and left in the area of the center of gravity (see Figure 14, no. 1).
By lifting the model right and left with your finger and balancing it, you will immediately find out whether the actual center of gravity is in the area of the adhesive strip.

Testing the remote control

Before you start using the transmitter, you should familiarise yourself with the controls.
a) Transmitter controls

1. LED indicator
2. Aileron and elevator joystick
3. On/off switch (see also Figure 17)
4. Aileron trim buttons
5. Elevator trim buttons
6. Motor function trim buttons
7. Trim buttons (without function)
8. Dual rate switch (see also Figure 25)
9. V-LAND switch (see also Figure 29)
10. Motor speed joystick
11. Reverse switches (see also Figs. 16 and 24)
    The model aircraft uses a non-hinged rudder. Therefore, the trim buttons (see Figure 15, no. 7) have no function and there is no need to move the joystick sideways (see Figure 15, no. 10) to control the model. When the motor speed joystick is moved up or down, it remains in its respective position. All other joysticks are automatically held in the middle position by spring force.

b) Inserting the batteries
The transmitter is powered by 4 AA/Mignon batteries (alkaline type recommended). Only use batteries to power the transmitter and do not use rechargeable batteries. Proceed as follows to insert the batteries:
The battery compartment cover (1) is located on the rear side of the transmitter. Press the two corrugated surfaces (2) and slide the cover downwards. Insert 4 AA/Mignon batteries into the battery compartment. First, insert the batteries in the right area and then slide them to the left under the bar (3). Observe the correct polarity of the individual cells. A respective note (4) can be found on the bottom of the battery compartment.
The spiral spring contact (5) must always be connected to the negative pole of the battery.
Then replace the battery compartment cover and push it upwards until it clicks into place.
c) Switching on the transmitter
Check the correct power supply of the transmitter by putting it into brief operation for test purposes.
Caution is important!
Before switching on the transmitter, always ensure that the motor speed joystick (see also Figure 15, no. 10) is in the lowest position since the flight controller and the motor are always activated when the model is started.
Otherwise, it may come to an activation of the programming mode on the flight controller. More information about the flight controller/programming mode can be found in section 12.

Then slide the on/off switch (see also Figure 15, no. 3) from the left position (OFF = switched off) to the right position (ON = switched on). The transmitter will emit a beep and the LED indicators (see also Figure 15, no.

1. will glow steadily.
   To switch the transmitter off again, slide the on/off switch back to the left switch position.
   When the power supply is not enough to ensure proper operation of the transmitter, the transmitter beeps in quick succession. In this case, discontinue using the model aircraft and replace the old batteries in the transmitter with new fresh ones.

Checking the remote control functions

First, start the transmitter. Make sure that the motor speed joystick (see Figure 15, no. 10) is in the lowest position.

a) Adjusting the transmitter trim
Before proceeding with mechanical adjustments of the model, be sure to check the digital trim on the transmitter. This is important because the trim setting is saved. The transmitter always resumes with the last trim values set before it was switched off.
The digital trim is set using the trim buttons (see Figure 15, nos. 4, 5, and 6). In this model aircraft, the trim buttons with position number 7 have no function. The complete trim range comprises approx. 20 individual steps in both directions when viewed from the middle position. The two end positions and the middle position are signaled acoustically by a longer beep.
Press all buttons one after the other and set the trim to the middle position. The transmitter beeps at every trim step. Then connect the flight battery to the flight controller. The flight controller emits four beeps via the motor. The model now responds to the remote control commands from the transmitter.

b) Checking the neutral position of the rudders
If you have already checked or readjusted the center position of the rudders when assembling the wings, the trailing edges of the ailerons must form a line (1) with the trailing edge of the wing.
If the ailerons are not accurately aligned, the wing must be removed again and the ailerons must be adjusted as shown in Figure 8.

The elevator linkage rod comes already prefabricated so no mechanical adjustment is required.
If the trailing edge of the elevator is not aligned with the trailing edge of the tailplane, use the trim on the transmitter to compensate for any deviation.

c) Checking rudder deflections and motor function
After adjusting the center position for all rudders, you can check and adjust rudder deflections.
Neutral position
In the neutral position, all the rudders must be in the middle position if the respective joysticks are also in the middle position. When checking rudder deflections, the motor speed joystick must be in the lowest position to prevent inadvertent start-up of the motor (see Figs.  20 -22).

Aileron control
When pushing the aileron and elevator joystick to the left, the left aileron should deflect upwards and the right aileron should deflect downwards (see light arrows in Figure 21). In this case, the model raises the right wing and lowers the left wing.
When pushing the aileron and elevator joystick to the right, the left aileron should deflect downwards and the right aileron should deflect upwards (see dark arrows in Figure 21). In this case, the model lowers the right wing and raises the left wing.

Elevator control
When pushing the aileron and elevator joystick down, the elevator should deflect upwards (see light arrows in Figure 22). This pushes the model’s tail down, causing the model aircraft to ascend if the motor power is sufficient.
When pushing the aileron and elevator joystick up, the elevator should deflect downwards (see dark arrows in Figure 22). This pushes the model’s tail up, causing the model aircraft to descend with the nose down.

Motor control
When moving the motor speed joystick up, the motor should start and speed up depending on the position of the joystick. The motor should turn clockwise when viewed from the rear.
Important!
When testing the motor function, the rotating and suction area of the propeller must be kept clear of loose objects, body parts, or hair.
Pushing the joystick all the way up sets the maximum motor power. As you push the joystick down again, the motor should slow down and come to a complete stop in the lowest joystick position (see Figure 23).

d) Setting the reverse switches
Should the rudders or the motor not respond as shown in Figs. 21 – 23, you can change the running direction of each individual channel.
This can be done by using four factory-set reverse switches on the remote control (see also Figure 16, no. 11).
The switches are assigned the following functions:
1CH = aileron
2CH = elevator
3CH = motor function
4CH = rudder (without function)
These switches enable you to set the correct running direction of the servos or the control function of the drive motor if necessary.

e) Setting the dual rate switch
The dual rate switch (D/R) enables to reduce of rudder deflections for the model to respond more smoothly to the control commands from the transmitter.
The dual rate switch is a slide switch located on the left side of the transmitter (see also Figure 15, no. 8). If the switch is in the right position (100%), the servos and thus also the rudders have the maximum deflection. Setting the switch to the left position reduces the travel of all servos to 70%.

f) Checking the V-LAND function
The model aircraft has a landing aid allowing its vertical landing without being damaged. For this purpose, the tailplane is unlocked and folds upwards by spring force.
The lock is released with the help of a servo that can be switched using the remote control. This function is assigned to a switch located on the left
side of the remote control transmitter (see Figure 15 and Figure 26, no. 9).
When the switch is in the right “OFF” switch position, the lock is engaged and the tailplane is in a horizontal position. This position is required for take- off and normal flight
operation of the model.
When the switch is pushed to the left “ON” position, the servo lever (1) pushes the lock linkage (2) forward and the tailplane (3) folds up.
Once unlocked by means of the remote control, the tailplane can only be reset by hand.
To lock the tailplane, set the V-LAND switch back to the “OFF” position. Then the tailplane can be folded onto the tail of the fuselage.
To lock the tailplane in this position, briefly push the release lever into the fuselage with your finger (see illustration in the middle in Figure 3).

Important!
Make sure that the lock linkage is not mechanically limited either in the locked or in the released position.
If necessary, the linkage can be easily adjusted by loosening the clamping screws on the screw nipple (see Figure 26, no. 4) and then re-tightening them.

Information about the flight controller

Important!
As already explained when switching on the remote control, the flight controller can be switched to pro- gramming mode. To prevent inadvertent switching, ensure that the motor function joystick is always in the lowest position when connecting the flight battery to the flight controller with the remote control switched on.
There is no need to modify programming in any way since the model aircraft comes with an already optimally factory-preset flight controller.

a) Beeps when switching on
When the flight battery is connected, the flight controller emits two identical beeps via the motor, indicating that a 2-cell flight battery has been connected. The two following beeps with different pitches indicate that the flight controller is working with the default setting and with the brake disabled.
If the motor function joystick is, for example, in the middle position instead of in the lowest position when connecting the flight battery, the flight controller will interpret this position as a reference point to switch off the motor. Since the motor control range is limited in this case, unplug the flight battery from the flight controller, push the motor unction joystick to the lowest position and then reconnect the flight battery.

b) Programming the joystick function
The flight controller should recognize the electronic signals for the two corner points or limit values in order to be able to optimally respond to the control commands for switching off the motor and running the motor with maximum power. Normally, there is no need to change this setting as it is factory preset.
It may be reasonable to reprogramme the corner points in the flight controller when using a different remote control.
Proceed as follows:

• Switch on the remote control and push the motor function joystick to maximum power.
• Now connect the flight battery to the flight controller.
• After the two beeps, push the motor function joystick to the lowest position (motor off).
• The flight controller emitting another two beeps indicates that it has recognized the lowest position.
• The flight controller then goes into ready status indicated by four regular beeps.

Flying the model

However, we recommend you contact an experienced model aircraft pilot or a model construction club in your area if you are not sure about how to fly a model aircraft.
If this is not possible, wait for a relatively windless day and look for a suitable flight location. A minimum distance of 150 m from industrial, commercial, residential, and recreational areas must be maintained. In addition, it is forbidden to fly near nature reserves.

a) Range test
Always ensure the flight battery has been charged according to the manufacturer’s instructions before the first takeoff. Also, use a battery tester to check the status of the transmitter batteries.
First, carry out a range test of the remote control on the flight location. Switch on the transmitter, and then turn on the receiver. Ask an assistant securely to hold the model as you check the range by slowly moving away from the model. Even with the motor running, all rudder functions should be reliably controllable up to a distance of at least 100 m.
Also, be sure to check the correct function and the running direction of the rudders as well as the correct locking of the tailplane. The vertical landing aid (V-LAND) switch should be in the “OFF” position and the D/R switch should be at 100%.

If the model flies beyond the remote control’s transmission range, thereby interrupting data transmission from the transmitter to the model, the motor will automatically switch off. The rudders will then remain in the position the last set with the remote control.

The running time of the motor depends on the required performance and can be up to 8 minutes in an energy-saving flight mode. Uninterrupted flying at maximum motor power significantly reduces the usable running time of the motor. Once you notice a significant drop in the motor performance, make sure you land your model immediately to avoid detrimental deep discharge of the flight battery.

b) First take-off
Ask a helper to launch the electric model running at full motor performance with a gentle push against the wind. The motor should work at 100% of its power.
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.
If assembled correctly, the model will ascend at a shallow angle, whereby the angle of the climb can be affected by the elevator. Do not attempt to steer it more than necessary. Only adjust the controls if the model changes its altitude, flies in a curve, ascends too rapidly or if the nose points downwards.
**** To sensitively correct the flight attitude and to carry out specific changes of direction in normal flight attitude, short and limited movements of the joysticks on the transmitter are sufficient.

c) Turning flight
Turning flight is initiated with the aileron; the model angles to the side. Once the model has reached the desired lean angle, the aileron joystick is pushed back to the center position. The curve can then be flown at a constant altitude by gently pulling the elevator joystick.
When the model flies in the desired direction, it is realigned horizontally by a brief aileron deflection in the direction opposite to the direction of the curve and the elevator is also brought back to the center position. If the model starts to sink in the curve, you did not pull the elevator joystick strongly enough. If the model starts to rise in the curve, you pulled the elevator joystick too strongly.
Pushing the aileron joystick insufficiently or for a very short time results in an extensive curve. Pushing the aileron joystick too hard or for too long results in a very narrow curve and extremely slanted model. In both cases, the aileron can be used at any time to correct a flight attitude.

Warning!
When flying, always ensure a sufficient flying speed. Pulling the elevator joystick too hard when the motor power is too low slows down the model drastically such that it can tip over forwards over the tip of the fuselage or sideways over a wing.
Therefore, ensure you fly at a safe altitude at the beginning until you get used to the control behavior of the model. Do not try to fly too far in order to be able to clearly evaluate, at any time, the flight attitude. When the model has reached a sufficient altitude, reduce the motor power and familiarise yourself with the slow flight characteristics of your model. You can even turn off the motor to save power. The model can fly and respond to control commands very well even without motor power.
However, always pay attention to the flight speed and do not slow down the model too much by pulling the elevator joystick too hard.
If necessary, switch on the motor again and only increase the motor speed until the model flies at a constant altitude. Reduced power consumption stresses less the flight battery and thus extends the running time of the motor.

d) Trimming the controls
You will be able accurately to trim your model once you have got a feel for it. Trimming can be used to correct the flight direction of your model should it tend to constantly fly in one direction in straight flight without the transmitter joysticks being manipulated.
Aileron trim:
If the model tends to roll around the longitudinal axis to the right, whereby the left wing tip is raised and the right wing tip is lowered, repeatedly press the left trim button (see also Figure 15, no. 4) for the ailerons (see white arrows in Figure 27). Continue pressing the button until the model no longer tends to roll. If the model tends to roll to the left,
use the right trim button (see dark arrows in Figure 27) for correction.

Elevator trim:
If the model tends automatically to ascend, repeatedly press the upper trim button (see also Figure 15, no. 5) for the elevator (see white arrows in Figure 28). Continue pressing the button until the model no longer tends to ascend. If the model tends to fly downwards, use the lower trim button (see dark arrows in Figure 28) for correction.

e) First landing
Standard landing
As with the take-off, the landing must always take place against the wind. To reduce altitude, you can fly large flat circles with no motor power. Do not pull the elevator joystick too hard so that the model does not become too slow. 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 correct the course significantly during the approach for a landing. If the model seems to drop altitude a little too quickly, simply switch on the motor in low power mode. The last part of the landing approach should be carried out with the motor switched off. Hold the model with the elevator in a horizontal position and wait until it drops altitude. When the model is approx. 50 cm off the ground, begin carefully to pull the elevator joystick harder such that the tip of
the fuselage is not raised too much. The model will slow down steadily until it finally lands gently.
Landing with the V-LAND function
When performing a vertical landing, the V-LAND switch unlocks the tailplane, thereby causing it to fold upwards. The tip of the fuselage will be raised and the wings will decelerate the rest of the forward travel. Since the model no longer has lift, the tip of the fuselage will be lowered, causing the model to sink down horizontally (see Figure 29). The model is kept balanced by the wings and the folded-up tailplane. Upon landing, make sure you set the V-LAND switch back to the “OFF” position and lock the tailplane by hand.

Caution is important!
You should first practice standard landing several times before attempting to perform a vertical landing. This is the only way you can effectively slow down the model before it sags due to insufficient lift.
When attempting your first vertical landing, fly the model to the landing point in the same way as during standard landing. When the altitude is low enough, press the V-LAND switch and follow the model.
If the model raises the tip of the fuselage much more than shown in Figure 29, this means that the flight speed is too high to initiate a vertical landing.
If the model fails to raise the tip of the fuselage despite the raised tail unit, the flight speed is too low.
Practice vertical landing at a low altitude until the model behaves as shown in Figure 29 and you get a feel for the right landing approach speed. You can then gradually increase the starting altitude for a vertical landing.

Our tip from experience:
In any case, we recommend that you resort to standard landing whenever possible for it is much more gentle for the model.

Upon landing, unplug the flight battery from the model and switch off the transmitter. Use a LiPo checker to check the remaining charge of the flight battery. It should not be less than 30%. A deep discharge can permanently damage the flight battery.
If necessary, you can readjust the aileron linkage such that the model flies straight and set the digital trim on the transmitter back to the center position.

f) Checking the center of gravity in flight
When you have a firm grip on your model after a couple of flights, you can optimize the flight performance by checking the center of gravity in flight and optimizing it if necessary. You would rather choose a windless day for that purpose. Let the model ascend to approx. 100 m and then switch off the motor.
With the motor switched off, the model should fly straight for a short time without loss of altitude. If necessary, perform a curve such that you can view your model from the side as it flies at a 90° angle to the viewing direction. Then briefly push the elevator joystick forward so that the model flies downwards at an angle of approx. 30°.

Without manipulating the elevator joystick, the model should automatically perform a gentle curve and then fly straight for a while (see Figure 30, sketch A). In this case, the center of gravity is set correctly. If the model automatically performs a narrow curve and then quickly raises the tip of the fuselage upwards, this means that the center of gravity is too far forward (see Figure 30, sketch B).
If the model fails automatically to perform a curve and does so only by pulling the elevator joystick, this means that the center of gravity is too far back (see Figure 30, sketch C).

If the center of gravity correction requires shifting the flight battery, the elevator trim must first be checked or adjusted before the next test.

Pairing function

To ensure that the 2.4 GHz remote control can transmit a signal without interference, the remote control and receiver must have the same digital code. The digital encoding (the connection between the remote control and receiver) can be configured using the pairing function.
The remote control and receiver are usually already paired when they leave the factory and can be used straight away. The devices only need to be paired again if the remote control or receiver has been replaced or to correct a malfunction.
To re-pair the receiver, proceed as follows:

• The transmitter and receiver must be in close proximity to each other and away from any other 2.4 GHz transmitters (Internet routers or similar hardware).
• Push the motor function joystick to the lowest position and switch on the transmitter.
• Connect the flight battery to the model.
• Press and hold the pairing button (1) on the receiver until the LED (2) flashes red. Upon releasing the button, the receiver LED should light up green. The receiver is now paired with the transmitter.
• Check whether the model responds correctly to the control commands from the transmitter.

Maintenance and cleaning

Check the rudder linkages and the control functions of the servos on your model regularly. All moving parts should move freely, but there must be not any slackness in the bearing.
The motor should turn easily by hand and the propeller should not be damaged or torn. Replace the worn propeller with the included replacement propeller or order an original replacement propeller. Cracks or breaks can be repaired with instant glue. However, the instant glue must be suitable for foam materials. During repair work, always pay attention to the weight and use as little glue as necessary. When repairing the wing, the model must eventually be balanced around the longitudinal axis. Trim weights must be placed in the lighter wing such that the model is properly balanced.
It is not recommended to repair a defective servo or receiver. In this case, it is useful to replace the defective parts with structurally identical ones.
Clean the exterior of the model and the remote control with a soft, dry cloth or brush. Never use aggressive cleaning chemicals or detergents, as these may damage the surface of the boat.
