Took the Q up to film some fireworks and was about 250ft up and 400ft out just hovering. Lost connection pops up on the screen and sure enough no stick control for around 30-40 seconds then got it back. This is the second time it's happened, with about 10ish flights in between. First 300ft up and 800 ft out. Both I had direct line of sight, no buildings, trees, open desert. I have 4k model with rakon frame. Any thoughts?
