3. Setup Guide
3.1 Battery Installation
Ensure the drone battery is fully charged before first use. Insert the charged battery into the drone's battery compartment, ensuring it clicks securely into place. For the remote control, install the required batteries.
3.2 App Installation and Wi-Fi Connection
Download the official SIMREX drone application from your device's app store (Apple iOS / Android compatible). Turn on the drone and your smartphone's Wi-Fi. Connect your smartphone to the drone's Wi-Fi network (usually named "SIMREX-X900" or similar). Open the app to view the live FPV feed and access advanced controls.
3.3 Frequency Binding and Calibration
To ensure stable flight, perform frequency binding and calibration before each flight. This process synchronizes the drone with its remote control and calibrates its internal sensors.

- Power On Drone: Long press the power button on the drone. Ensure the camera faces forward and place the drone on a horizontal surface.
- Power On Controller: Press the power button on the remote control.
- Bind Frequency: Push the left joystick upwards then downwards. The drone's lights will change from flashing to steady, indicating successful connection.
- Calibrate: Push both the left and right joysticks 45° outwards simultaneously. The drone's flashing lights will change to steady, confirming successful calibration.
- Unlock Motors: Push both the left and right joysticks 45° inward simultaneously. The propellers will begin to spin slowly, indicating the motors are unlocked and ready for flight.
4. Operating Instructions
4.1 Basic Flight Operations
Familiarize yourself with the remote control layout and functions before attempting flight.
- Take-off: Push the left joystick upwards to take off, or long press the "One key rise" button for automatic take-off.
- Landing: Push the left joystick downwards to land, or long press the "One key fall" button for automatic landing.

4.2 Special Flight Modes
- Altitude Hold: Release the throttle stick, and the drone will maintain its current height, allowing for stable hovering.
- Headless Mode: In this mode, the drone's orientation is relative to the pilot, eliminating the need to adjust its position before flying. This is particularly helpful for beginners.
- 360° Flips: Execute impressive aerial acrobatics with a single button press.
- Waypoint Fly: Plan custom flight paths on the app interface, and the drone will automatically follow the designated route.
- Gravity Control: Control the drone's movement by tilting your smartphone, offering an intuitive flight experience.

- Battery Care: Store batteries in a cool, dry place. Do not overcharge or over-discharge. If storing for extended periods, charge to approximately 50%.
- Storage: When not in use, fold the drone arms to save space and store it in a safe, dry environment away from direct sunlight and extreme temperatures.
6. Troubleshooting
| Problem | Possible Solution |
|---|---|
| Drone does not respond to controller. | Ensure both drone and controller are powered on and successfully bound (refer to Section 3.3). Check controller batteries. |
| Drone is unstable during flight. | Perform calibration (Section 3.3) on a flat, horizontal surface. Check for damaged propellers and replace if necessary. Avoid flying in windy conditions. |
| No live video feed on smartphone. | Ensure your smartphone is connected to the drone's Wi-Fi network. Restart the drone, controller, and app. Check app permissions. |
| Short flight time. | Ensure the battery is fully charged. Flight time can be affected by aggressive flying or strong winds. Consider purchasing additional batteries. |
