Setup Guide
1. Unboxing and Components
Upon opening the package, verify that all components are present:
- SYMA X400 Mini Drone
- Remote Control
- 2 x Modular Batteries
- USB Charging Cable (Note: Wall charger not included)
- Replacement Rotors
- Rotor Guards
- Instruction Manual
2. Battery Installation and Charging
Install the modular batteries into the drone. Connect the drone's battery to the USB charging cable. A full charge takes approximately 90 minutes via USB. Ensure the drone is fully charged before its first flight for optimal performance. For the remote control, four AA batteries (not included) are required. Insert them into the battery compartment on the back of the remote.
3. App Installation and Connection
Download the 'SYMA Fly' app from your device's app store. Once installed, connect your smartphone to the drone's Wi-Fi network (usually named 'SYMA-X400' or similar) before launching the app. The app provides an alternative control method and enables advanced features like FPV and flight path mode.
Operating Instructions
1. Basic Flight Controls
Familiarize yourself with the remote control or app interface. The left joystick typically controls throttle (up/down) and yaw (rotation left/right). The right joystick controls pitch (forward/backward) and roll (sideways left/right). Always ensure the drone is calibrated before flight to prevent unintended movement.
2. User-Friendly Features
- One Key Take-off/Landing: Press the dedicated button to automatically launch or land the drone. This simplifies initial flight and safe return.
- Altitude Hold Mode: This feature allows the drone to maintain a stable altitude, making it easier to control and capture steady footage.
- Headless Mode: In Headless Mode, the drone's orientation is relative to the pilot, eliminating the need to adjust its position before flight. This is particularly helpful for beginners.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your SYMA X400 drone.
- Cleaning: Gently wipe the drone's body with a soft, dry cloth after each use to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
- Propeller Inspection: Regularly check the propellers for any signs of damage, cracks, or bends. Damaged propellers can affect flight stability and safety. Replace them using the provided spare parts if necessary.
- Battery Care: Store batteries in a cool, dry place. Do not overcharge or completely drain the batteries. If storing for an extended period, charge them to about 50% capacity.
