I have really got to know my phantom 3 well inside and out. Unfortunately it was through the school of hard knocks. I have put in water 3 times, lost compass and while it went out of control brought in down in a hay field. I learned that atti mode doesn’t like to stop quick and hit the back of my trailer. I hit low branches and it fell 10 ft. twice. I hit me once. After it was under a waterfall for 3 Days my wife told me not to fix it. She said buy a p4 with obstacle avoidance. I agreed. Today I was putting things together to sell the p3 for parts. I don’t have a battery so I powered it up with the charger and it went through the dance. Most all of my p3 is working. The camera works, the gimbal works even with a broken WiFi cable. I looked at the app and it says that I an not using a DJI battery and won’t let me fly. It says compass is good and imu also. Wow. $18 for WiFi antennas and a $124 for a battery. This thing should fly. Still my wife says sell. We aren’t putting any money into it.
