Question 1. Why does the drone periodically stop in the air during an automatic route flight?
Answer: the front sensors of the vision positioning system of the TOPODRONE DJI Air 2S PPK can periodically be blinded by light. This is not a defect: it is caused by the dual front sensor system of the drone. If this happens, it is recommended to disable the vision positioning system. See details here.
Question 2. Why does the TOPODRONE DJI Air 2S PPK need a constant radio link through the remote controller to fly a waypoint route?
Answer: waypoint flight of the TOPODRONE DJI Air 2S PPK uses the so-called «virtual sticks» technology, where the app and the remote controller take full control of the drone. See details here.
Question 3. Why was no *.ubx file created on the memory card after several flights?
Answer: After initialization and normal indication of the TOPODRONE DJI Air 2S PPK receiver, the *.ubx file is created automatically and recording to the memory card starts. There are no documented cases where the *.ubx file was not created with correct indication of the TOPODRONE DJI Air 2S PPK receiver. Check the LED status before every flight. In the vast majority of cases, a missing *.ubx file was caused by the TOPODRONE DJI Air 2S PPK receiver not having been initialized because of operator inattention.
