so I started using healthy drones. Wow. What an amazing tool! I notice my drone is pretty healthy, but some things concern me. Mainly the GPS signal sensor. I'm always in the orange (good) but sometimes dip into red (poor) during my flights. This happened in the hand full of locations I've flown at all over the east coast. Is this normal? Is this safe? Do I need a P3A? Lol Thanks!
