I have a relatively new P4. I am using an NVIDIA k1 tablet to run DJI Go 3.1.1. This combination seems to work pretty well. I just bought Litchi. I could use my LGG4 cell phone to transfer data to Healthy drones (where I do have service). However I plan to fly in some areas where there is no cell service. Can the flight data be loaded to Healthy drones later? If so how is this done? I am a relative NOOB to all this stuff TIA
