Opsætning
1. Opladning af batteriet
Connect the drone battery to the USB charger and plug it into a USB power source (e.g., computer USB port, USB wall adapter). The indicator light on the charger will show charging status. Ensure the battery is fully charged before each flight for optimal performance and flight time.
2. Installation af propeller
The propellers are marked with 'A' or 'B'. Match them to the corresponding motor arms. Ensure they are securely fastened. Incorrect installation will prevent the drone from flying correctly.
3. Opsætning af controller
Install the required batteries into the remote control. Ensure correct polarity. Power on the remote control.
4. App Installation (Optional for FPV)
For FPV (First Person View) and advanced control features, download the official SIMREX drone app from your smartphone's app store (iOS/Android compatible). Søg efter "SIMREX FPV" or refer to the QR code in the quick start guide if provided.
Betjeningsvejledning
1. Parring af drone og fjernbetjening
- Placer dronen på en flad, plan overflade.
- Tænd dronens strømafbryder. Dronens indikatorlamper vil blinke.
- Tænd for fjernbetjeningen.
- Push the left joystick (throttle) all the way up, then all the way down. The drone's lights will become solid, indicating successful pairing.
2. Kalibrering
After pairing, perform a gyroscope calibration for stable flight. Push both joysticks to the bottom-right corner simultaneously until the drone's lights flash rapidly and then become solid again. This indicates successful calibration.
3. Start og landing
- Start med én knap: Press the One-Key Takeoff/Landing button. The drone will automatically ascend and hover at a stable altitude.
- Manuel start: Slowly push the left joystick (throttle) upwards. The propellers will spin, and the drone will ascend.
- One-key landing: Press the One-Key Takeoff/Landing button again. The drone will automatically descend and land gently.
- Manuel landing: Slowly pull the left joystick (throttle) downwards until the drone lands. Once landed, push the joystick all the way down to stop the motors.
4. Flykontrol og funktioner

Image: The SIMREX X900 drone hovering above a grassy field, with an arrow indicating its stable altitude. Text highlights "ALTITUDE HOLD" and explains that releasing the throttle stick will maintain the current height.
Højdehold: The drone is equipped with an advanced barometer to automatically maintain its current altitude. You can release the throttle stick, and the drone will hover steadily at that height, making it easier to control and capture stable photos/videos.

Image: The SIMREX X900 drone viewed from above, with arrows indicating movement directions relative to the pilot. Text highlights "HEADLESS MODE" and explains that once activated, the pilot can fly the drone without worrying about its orientation.
Hovedløs tilstand: Activate Headless Mode by pressing the dedicated button on the remote. In this mode, the drone's forward direction is always relative to the pilot, regardless of the drone's actual orientation. This simplifies control, especially for beginners.

Image: Three instances of the SIMREX X900 drone performing a 360-degree flip in mid-air, illustrating the "3D STUNT" feature. Text indicates "360° flips and rolling with one single button."
3D Flips (Stunt Mode): To perform a 360-degree flip, press the 3D Flip button on the remote control, then quickly push the right joystick in the desired flip direction (forward, backward, left, or right). Ensure sufficient altitude before attempting flips.

Image: A hand holding the SIMREX X900 drone's remote control, with a blurred background showing the drone flying. Text describes "GRAVITY SENSOR MODE ON PHONE APP & CONTROLLER," explaining that both the phone app and controller can operate by activating gravity sensor mode, controlling flight by holding and moving the device.
Tyngdekraftssensortilstand: When using the smartphone app, you can activate Gravity Sensor Mode. This allows you to control the drone's pitch and roll by tilting your smartphone, providing an intuitive flight experience. This mode can also be activated on the controller.

Image: Two options for controlling the SIMREX X900 drone: "PHONE WIFI DIRECT CONTROL" showing a smartphone with on-screen controls, and "TRANSMITTER CONTROL WITH PHONE MONITOR" showing the remote control with a smartphone mounted. Text indicates iOS/Android compatibility for phone control.
FPV and WiFi Live Video: Connect your smartphone to the drone's WiFi network (SSID usually starts with "SIMREX" or "X900"). Open the SIMREX app to view a live video feed from the drone's 1080P HD camera. You can also control the drone directly from the app or use the remote control with your phone as a monitor.

Image: The SIMREX X900 drone shown in both its folded and unfolded states, with dimensions provided. Text highlights "FOLDABLE DESIGN" and states it "Saves the space & easy to carry." Aircraft folding size is 138x93x48mm, and unfolding size is 383.2x356.7x88.4mm.
Sammenfoldeligt design: The SIMREX X900 features a foldable arm design, allowing for easy storage and portability. To fold, gently push the arms inwards towards the drone's body. To unfold, pull the arms outwards until they click into place. Ensure all arms are fully extended before flight.
Opretholdelse
- Rensning: Brug en blød, tør klud til at rengøre dronen og fjernbetjeningen. Brug ikke skrappe kemikalier eller opløsningsmidler.
- Propelinspektion: Kontrollér regelmæssigt propeller for skader (revner, bøjninger). Udskift beskadigede propeller med det samme med de medfølgende reservedele.
- Batteripleje: Opbevar batterier et køligt og tørt sted. Opbevar ikke fuldt opladede eller helt afladede batterier i længere perioder. Oplad dem til ca. 50% ved langtidsopbevaring.
- Opbevaring: When not in use, store the drone in its original packaging or a protective case to prevent damage.
Fejlfinding
| Problem | Mulig årsag | Løsning |
