That's a nice fleet. I know all about your situation. I have currently have 3 drones and one of them rarely gets flown, the other I have never flown. I bought a backup P4P with 1.3.509 with hacked flight ceiling, just in case I lose my original "mountain climber". I've never flown the backup, other than a test flight when I originally bought it. A year ago I had 5 DJI drones. My wife was surprised when I sold my P3P a year ago, and then sold my P4 about 6 months later. The P3P was emotionally the toughest to sell. It was my first DJI drone. I flew that bird in a lot of places around the country, even the statue of liberty. I really didn't want to sell it, but I never flew it anymore, it had to go.
