Your drone will not connect to WiFi.
Your drone will need to pair with the mobile app on your device to connect to WiFi. To download the app, you can either scan the Quick Response (QR) code found in the drone instruction manual, or on the box. If you cannot find the QR code, you can search for the app in your device’s app store using the search tag provided in the instruction manual.
Ensure you are within the 82 foot WiFi-control radius. If not, your drone is out of range. You must operate your drone within this range.
The signal transmitting from your drone to your device may be experiencing interference from a nearby power source such as power lines or cell phone towers.
Scan the area of your flight zone for any such source and redirect your drone’s flight path away from the source.
There are two ways to control your drone: from the controller or from the app on your device. When switching between the controller and device, pull the throttle stick on the controller to the lowest position before switching.
Ensure the indicator light on the controller is on. If it is on, there may be signal interference. Turn both the drone and the controller off, wait five seconds, then restart the drone and power on the controller. If the indicator light does not turn on, the controller battery needs to be replaced. For steps to do so, please visit the Udi Discovery U818A FPV Controller Battery Replacement.
The camera fails to switch on or turn off.
The camera is controlled through the mobile app on your device. The controller is not designed to operate the camera.
Crash landings or inflight bumps to the drone can sometimes cause the camera to unplug from the device. Check the camera’s connector wire, and reconnect if necessary.
If the camera has been damaged, it will need to be replaced. For steps to do so, please visit the Udi Discovery U818A FPV Camera Replacement.
Pictures and video stored on your drone’s SD Card will not transfer to your device.
Ensure the SD card is properly seated in the SD-card slot located on the camera. To do so, remove the SD card from the slot, make sure the metal side of the card is facing up, and then reinsert the card into the slot.
If the SD card is seated properly and you still cannot view images, the card may need to be reformatted.
