Made in China

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated underscores where none should exist based on the GT's visual context. Hence, the OCR result is inconsistent with the Ground Truth.

INSTRUCTIONS AND USER MANUAL

SZD 54

GENERAL INFORMATION

• The model is designed for the components specified by us. Unless otherwise stated, servos and other electronic components are designed for standard supply voltage. Recommended cell count for Lipo batteries also refers to standard Lipos voltage of 3.7V per cell. If you use other servos, a different motor and controller, batteries, or propellers, please make sure they fit first. In the event of deviations, corrections and adjustments must be made by yourself.
• Before starting construction, always put the servos into neutral. To do this, switch on the remote control and move the joysticks and trim buttons (save the one for the throttle) to the middle position. Connect the servos to the corresponding outputs of the receiver and supply them with a suitable power source. Please observe the connection diagram and the operating instructions of the remote control system manufacturer.
• Do not leave your model in the blazing sun or in your vehicle for long periods of time. Too high temperatures can lead to deformation/distortion of plastic parts or blistering of covering foils.
• Before the first flight, check the wing symmetry, tail unit and fuselage. All parts of the model should have the same spacing from the left and right wing or tail plane to the centre of the fuselage or the same angle.
• If necessary, rebalance the propellers if vibrations are noticeable when the motor is running up.
• Bubble formation in the covering foils normal to a certain extent due to temperature and humidity differences and can be easily eliminated with a foil iron or hairdryer.
• For models in shell construction ("full GFRP/CFRP"), burs may occur at the seams due to the production process. Carefully remove them with fine sandpaper or a file.

GENERAL SAFETY INFORMATION

• Be sure to read the safety instructions carefully before operating your model.
  • Always follow the procedures and settings recommended in the instructions.
• If you are using remote controlled model aircraft, helicopters, cars or ships for the first time, we recommend that you ask an experienced model pilot for help.
• Remote controlled models are not toys in the usual sense and may only be used and operated by young people under 14 years of age under the supervision of adults.
  • Their construction and operation requires technical understanding, careful craftsmanship and safety-conscious behaviour.
• Mistakes or negligence during construction, flying or driving can result in considerable damage to properly or personal injury.
• Since the manufacturer and seller have no influence on the proper construction/assembly and operation of the models, these risks are expressly pointed out and any liability is excluded.
• Propellers on aircraft and all moving parts in general pose a constant risk of injury. Avoid touching such parts at all costs.
• Note that motors and controllers can reach high temperatures during operation. Avoid touching such parts at all costs.
• Never stay in the danger area of rotating parts with electric motors with connected drive battery.
  • Overcharging or incorrect charging can cause the batteries to explode. Make sure the polarity is correct.
• Protect your equipment and Models from dust, dirt and moisture. Do not expose the equipment to excessive heat, cold or vibration.
• Use only recommended chargers and charge your batteries only up to the specified charging time. Always check your equipment for damage and replace defects with original spare parts.
• Do not use equipment that has been damaged or got wet cue to a fall, even if it is dry again! Either have it checked by your specialist dealer or in the Robbe Service or have it replaced. Hidden faults can occur due to wetness or a crash, which lead to a functional failure after a short operating time.
• Only the components and accessories recommended by us may be used.
• Do not make any changes to the remote control which are not described in these instructions.

1. ASSEMBLY OF THE TAILPLANE:

Position the tailplane as shown in the illustration at the fuselage end and screw it tightly to the fuselage from above using the M4x25 screw. Make sure that the screw is firmly seated and do not overtighten the screw!

2. ASSEMBLY OF THE RUDDER:

Insert the rudder into the recess provided for this purpose on the fuselage and tighten it with screw M4x35 from below. Make sure that you also have a light fit without damaging the screw connection!

3. RUDDER CONNECTIONS:

too tight!

optimal!

The two clevis heads for the rudder and elevator must now be mounted in the corresponding rudder horn on the 3rd hole and screwed tight.

Make sure that the screw is only tightened firmly, that the linkage remains smooth running!

4. ASSEMBLY OF THE WINGS:

The two wing halves are attached to the fuselage by means of CRP tube 10mm. At the same time, thread the servo connection cable through the hole provided on the fuselage and make sure that the servo cable is not jammed! The wings are secured to the underside of the wing by means of a screw on the underside of the wing. Make sure that you are seated safely without damaging the screw connection by stretching it over! The two winglets have to be fixed to the edging arch with screws M3x10.

5. ELECTRICAL CONNECTION:

Now all servos must be connected to the receiver according to the sequence of connections of your remote control system. If your remote control system cannot handle two aileron servos, the model is supplied with a V-cable for one receiver channel.

The controller is also connected to the receiver.

6. FINAL ADJUSTMENTS:

Elevator Rudder Aileron

Next, all rudder functions and engine control on the transmitter must be set. In case of rudder deflections, we recommend that you use the following values for your first flight, which you can later adjust to suit your personal preferences.

ATTENTION: We recommend that you disassemble the propeller for safety reasons during all adjustment work on the remote control system in order to avoid injuries caused by e. g. sudden starting of the engine.

INSTRUCTIONS AND USER MANUAL

SZD 54

7. CENTER OF GRAVITY:

In order to achieve maximum flight performance, a correct centre of gravity is essential. For the first flight, make sure that the centre of gravity of 60mm behind the leading edge (measured at the fuselage base) is reached by moving the battery. Ideally, the fuselage should be levelled with the correct centre of gravity and a lightly suspended nose.

ATTENTION: if the centre of gravity is not correct, this can lead to a fall and may result in the following lead to property damage and personal injury!

8. TIPS AND NOTES FOR THE FIRST FLIGHT:

Before the first flight, check again that all mechanical and electrical connections are tightly connected. We also recommend to check this before every flight, as well as the direction of action of the control deflections!

ATTENTION: Loose wings, or other parts of the model may cause a crash. lead to property damage and personal injury!

Use the model only on suitable flying terrain and make sure not to endanger pedestrians in the vicinity or properly!

To get the model into the air, all you need to do is to push the model lightly by hand with the motor switched on and the trajectory slightly filled upwards. The model should then take off slightly uphill. Otherwise, trim corrections must establish the desired flight direction. The effectiveness of the rudders and the individual control deflections can then be flown at a sufficient altitude. The optimum centre of gravity can also be checked by slightly "pressing" the centre of gravity (soft inclination downwards) and then observing the interceptor sheet. The rule of thumb applies here, if the model's intercept sheet is too abrupt without the need for tax inputs, the model is too low-heavy. By contrast, the model would be too fail-heavy if it maintains its trajectory or even tends towards the ground!

2. Programmable adjustments:

1. Brake: enabled / Disabled
2. Battery type: Lipo / NiMH
3. undervoltage protection (Cut-Off Mode): Soft Cut-Off (Gradual reduction of power) / Cut-Off (Immediate standstill)
4. cut-off voltage for undervoltage protection (cut-off threshold): low / medium / high

1) For lithium batteries, the number of cells is calculated automatically.

Low / Medium / High cut-off voltage for each cell is: 2.85V/3.15V/3.3V.

For example: For a 3S LiPo, with „Medium“ switch-off setting, the switch-off voltage is 3.15V x 3 = 9.45V.

2) For NiMH batteries the cut-off voltage is: low 0% / medium 50% / high 65% of the output voltage (e.g. the nominal voltage of the battery pack) and 0% corresponds to the deactivated undervoltage protection.

For example: For a 6 cell NiMH battery the voltage after charging is 1.44V x 6 = 8.64V, for „medium“

setting the cut-off voltage is 8.64V x 50% = 4.32V.

1. Start mode: Normal /Soft /Super-Soft (300ms / 1.5s / 3s)

Normal mode is suitable for any aircraft. Soft or Super-Soft Mode is suitable for helicopters.

The first start in soft and super soft mode is slower, it takes 1.5 seconds for soft start or 3 seconds for super soft start from first start to full throttle. When the throttle is fully released (throttle lever in lowest position) and is operated again within 3 seconds (throttle lever in full throttle position), the repeated throttle shock is performed temporarily in normal mode to avoid the possibility of a crash due to too slow a throttle reaction.

This special function is especially useful for aerobatics, where fast throttle reactions are necessary.

1. Timing: Low 3.75°/ Medium 15°/ High 26.25°

Normally a low setting is suitable for most engines. For more speed a higher timing setting can be selected.

SZD 54

3. Using the ESC

IMPORTANT! Due to different throttle ranges with different remote controls please calibrate the throttle range before the first flight!

Throttle adjustment:

(The gas range should be reset each time the remote control is changed.)

1. Switch on the radio with throttle stick up (full).
2. Connect flight battery and wait for approx. 2 sec.
3. A "beep" sound should be heard, this confirms the setting of the full throttle position.
4. Put the throttle stick to lowest position, more "beep" sound should be heard, which show the number of cells
5. A long "beep" sound should be heard which confirms the lowest throttle stick position.

Normal Start-Up procedure

1. Throttle stick to lowest position, switch on radio.
2. Connect battery to ESC. Special tone as "123" means the voltage input is ok.
3. More "beep-" Iones should be heard to show the number of cells.
4. A long "beep" lone sounds after self-lesl.
5. Move the throttle stick upwards to increase the power.

Safety functions

1. Startup Fault protection: If the motor is not started within 2 seconds after throttle movement starts, the controller switches off the throttle function. In this case the throttle MUST be reset to the lowest position. (Such a situation occurs as follows: The connection between governor and engine is not stable, the propeller or engine is blocked, the gearbox is damaged, etc. (The throttle is in the lowest position).
2. Overheat protection: If the temperature of the controller rises above 110° C, the controller reduces the output power.

3. Lost of transmitter signal: The controller reduces the output power if the transmitter signal fails for 1 second, further loss for 2 seconds causes the output power to be switched off.

4. Troubleshooting

Failure Possible cause Solution
After switching on, the motor does not work, no tones can be heard.	The connection between ESC and battery is not correct.	Check the connection carefully. Change the connectors.
After switching on, the motor does not work, the following warning tone is heard: „beep-beep-, beep-beep-, beep-beep-“ (each „beep-beep-“ has an interval of approx. 1 second)	Input voltage is not normal, too high or too low.	Check the battery voltage.
After switching on, the motor does not work, the following warning tone can be heard: „beep-, beep-, beep- „(each „beep-“ has an interval of approx. 2 seconds)	Throttle signal is not correct.	Check radio and receiver. Check servo wire of ESC to receiver.
After switching on, the motor does not work, the following warning tone is heard: „beep-, beep-, beep-“ (every beep- has an interval of 0.25 seconds)	The throttle stick is not in lowest position.	Move the throttle stick to the lowest position.
After switching on, the motor does not work, the following warning tone „56721“ can be heard after 2 beep lones (beep- beep-)	Throttle is reversed, ESC is in programming mode.	Change the direction of throttle (servo reverse).
Motor turns in wrong direction	Change the connection between motor and ESC.	Exchange two connecting cables between motor and controller at random.

5. Programming the ESC with the transmitter (4 steps)

Note: Please note that the throttle curve is set to 0%, the throttle lever to neutral position and the deflection to 100%.

1. Start programming mode
2. Select program point
3. Setting the program point (value)

4. Exit programming mode.

5. Start programming mode

1) Switch on transmitter, set throttle stick to full throttle, connect battery to ESC
2) Wait 2 sec., a double „beep“ must be heard
3) Wait another 5 sec., special tone like "56721" should be heard. This confirms the programming mode.

3. Setting the program point (value)

You hear different tones in a loop. Set the value by tone by moving the throttle to full throttle. Then you hear a special tone „1515" which confirms and saves the selection. (Holding the throttle to full throttle brings you back to step 2 and you can select another point. Moving the throttle lever to the neutral position within 2 seconds will exit the programming mode.)

Point Tone

"beep-" "beep-beep-" "beep-beep-beep"1 short tone 2 short tones 3 short tones
Brake Off On
Battery type Lipo NiMH
Cut-Off Soft-Cut Cut-Off
Cut-Off voltage Low Medium High
Start mode	Normal	Soft	Super Soft
Timing	Low Medium High

2. Select program point

After starting the programming mode you will hear 8 tones in a loop with sequence. If you move the throttle to the neutral position within 3 seconds after listening to a tone, this point will be selected.

1. "beep"	Brake	(1 short tone)
2. "beep-beep-"	Battery lype	(2 shortl tones)
3. "beep-beep-beep-"	Lower voltage	(3 shortl tones)
4. "beep-beep-beep-beep-"	Cut-Off voltage (4 short tones)
5. "beep----"	Start Mode	(1 long tone)
6. "beep----beep-"	Timing	(1 long 1 short)
7. "beep----beep-beep-"	Factory reset	(1 long 2 short)
8. "beep----beep----"	Exit	(2 long tones)

4. Exit programming

There are two ways to exit the programming:

1. In step 3, after the special tone „1515“, move the throttle stick to the neutral position within 2 seconds.
2. In step 2, after tone „beep----beep „ (e.g. point 8) bring throttle stick inner 3 sec. Into neutral position.
