A: This is typically caused by signal interference. To ensure a clean, stable communication link between the remote controller and the aircraft, the controller's Wi-Fi may interfere with video transmission and control signals.

Solution:
Before or during flight, please just navigate to the remote controller's settings and make sure its Wi-Fi is turned off to achieve the best connection performance.

A: "Follow Mode" relies on the remote controller's GPS to determine your location. If the controller's GPS signal is weak or has not acquired a position, the function will not execute.

Solution:
 1. Confirm GPS Signal: Please fly in an open, outdoor environment and ensure the remote controller's GPS status on the APP interface shows a successful lock.

 2. Verify Positioning: Walk a few steps while holding the remote controller, then check the APP's map interface to see if the controller's position icon (usually a red dot) moves accordingly. If the icon does not move, please wait for the GPS to lock successfully before using this feature.

A: In "Follow Mode," the aircraft's maximum flight speed is approximately 28.8 KM/H.

Recommendation:
To ensure effective tracking and flight safety, please ensure your (the remote controller's) movement speed does not exceed the maximum speed.

A: This is a normal phenomenon. The aircraft primarily uses a barometer to sense altitude. Airflow near the ground, especially in complex environments, is often turbulent, which can cause minor fluctuations in the barometer readings and lead the aircraft to make altitude corrections.

Recommendation:
When hovering at an ultra-low altitude of 1-2 meters, be prepared to make manual altitude adjustments at any time.

A: Water surfaces can reflect signals, which may interfere with vertical signal transmission.

Solution:
When planning to fly over water for an extended period, it is recommended to adjust the remote controller's two antennas so that one antenna points vertically upwards and the other vertically downwards. This configuration optimizes omnidirectional signal coverage and reduces the risk of signal loss caused by water reflections.

A: In an ideal environment that is open, unobstructed, and free of electromagnetic interference, the maximum video transmission range can reach 7 kilometers. The actual distance will be affected by the environment (e.g., buildings and trees) and by interference sources (e.g., high-voltage power lines and signal towers).

A: Using the standard charger, it takes approximately 100 minutes to fully charge one battery.

A: Using the standard charger, it takes approximately 2.5 hours to fully charge the remote controller's built-in battery.

A: Proper maintenance can effectively extend battery life and ensure flight safety.

A: Yes, you can. To prepare for missions in areas with no cellular signal or network connection, such as remote fields or mountains, it is highly recommended that you cache the offline map of your mission area in advance while you have a Wi-Fi connection.

Part A: Appearance and Status Check

• Connect to Network: Ensure your remote controller is connected to a Wi-Fi network.
• Enter Map Interface: Open the SDFLY App and go to the main flight interface (the live camera view)
• Locate Target Area: On the map, use two fingers to pan and zoom to find the area where you plan to fly.
• Load Level by Level: This is a crucial step. You need to zoom in on the map progressively, from a wide overview to a detailed street-level view. Pause at each zoom level to allow the map tiles (the detailed map images) to load completely. Continue zooming until you can clearly see details like roads and building outlines.
• Pan Across the Entire Area: While at the most detailed zoom level, pan across the map to view every part of your potential flight zone. Ensure that the map details for the entire area have been displayed on your screen.
• Caching Complete: The app will automatically cache the map data you have viewed onto the remote controller's storage. When you are in the field without an internet connection, the map for these pre-loaded areas will be available.

Recommendations:
The larger and more detailed the area you cache, the more storage space it will consume.Periodically open the app while connected to a network to update or supplement your cached offline map data.

A: The payload release function allows for precise, segmented drops. The setup steps are as follows:

Steps:
1. On the APP's main interface, go to 【System Settings】>【Safety Settings】> Custom Button Settings.
2. Set C1 to 【Segmented Release】 and C2 to 【Full Release】.
3. After setup, you can control the release using the buttons on the remote controller's back.

A: No. To prevent accidental operation, the system is designed so that custom buttons C1 and C2 cannot be assigned to the "Payload Release" function at the same time. You can only choose one of these buttons to perform this action.

A: This is usually due to the high sensitivity of the zoom dial. When you stop turning the dial and release it, it may not return to the exact center. This slight deviation is registered by the system as a new input, causing the focal length to jump back.

Recommendation:
Try to operate the dial slowly and smoothly. After reaching your desired focal length, consciously ensure the dial is stable in its center position.

A: The remote controller's power-off function has an anti-mistouch design.

Correct Procedures:

• Long Press Shutdown: Please press and hold the physical power button for more than 3 seconds until the shutdown prompt appears on the screen.
• Software Shutdown: You can also go to the remote controller's 【System Settings】 menu, find the 【Shutdown】 option, and tap it to turn off the controller.

A: The remote controller has a water-resistant design. Due to temperature or air pressure changes, a pressure differential can build up inside, creating this "puffy" sensation.

Solution:
Please open the waterproof plug of the charging port at the bottom of the remote controller to equalize the internal and external pressure. This usually resolves the issue immediately. Remember to close the plug after you are done.

A: This may be due to a temporary glitch in the gimbal's software.

Solution:
Immediately find a safe place to land the aircraft. After landing, power the aircraft off and then on again. This usually resolves the issue. If the problem occurs frequently, try performing a 【Gimbal Calibration】 in the APP's System Settings > Gimbal Settings.

A: This can be caused by several factors.

Troubleshooting Suggestions:

• Signal Interference: Check if there is strong signal interference in the current flight environment or if the aircraft is too far from the remote controller.
• APP Performance: Try restarting the remote controller or the SDFLY3 App to free up system resources.
• Hardware Performance: Ensure the remote controller has sufficient battery power.

A: This happens when the memory card's write speed cannot keep up with the high bitrate of the video data stream. When the speed is insufficient, the camera automatically saves the video in segments to ensure no data is lost.

Solution:
It is recommended to replace the memory card with a faster high-speed Micro SD card (e.g., U3/V30 class or higher).

A: This is usually a temporary interruption caused by a momentary, strong interference in the video transmission link.

Solution:
If it happens only for a moment and recovers on its own, no action is generally needed. If the screen goes black frequently or for an extended period, return to home immediately. After landing, restart the aircraft to see if the problem persists.

A: The gimbal's horizontal value may need to be calibrated.

Solutions:

• Quick Fix: After landing, restart the aircraft. The gimbal's self-check upon startup will usually correct the issue.
• Permanent Fix: If the problem persists, place the aircraft on a perfectly level surface. Go to the 【Gimbal Settings】 in the APP and perform a 【Gimbal Calibration】.

A: This may be due to high system resource usage or a temporary software conflict.

Troubleshooting Steps: Please try the following steps in order:

• Restart the App: Go to the remote controller's background task manager, completely close the SDFLY3 App, and then reopen it. 
• Restart the Remote Controller: If restarting the app doesn't work, press and hold the power button to restart the entire remote controller. This is one of the most effective solutions.
• Check for Updates: Ensure that your SDFLY3 App and remote controller firmware are updated to the latest versions. New versions often include bug fixes and stability improvements.

A: This is also likely caused by the app being temporarily unresponsive.

Solution: First, try restarting the SDFLY3 App. If the problem continues, restart the remote controller. In an emergency, you can also use the physical "Return to Home" (RTH) button on the remote controller to trigger the function.
