Ive had my phantom for just over a year made lots of flights, today wasnt a good day. First my battery ran down from 100-5 in about 3 mins, lucky i noticed it just in time and was able to get it down @ 4%. Never had that happen before, i have 4 batteries that i cycle through. Next im flying and the drone, and i see it spin on the screen then static look up to see it falling out of the sky. Luckily it was above an open field but it fell a good 50m-70m and got pretty messed up, it going to need some serious repairs, probably just get a replacement. My main concern is diagnosing what happened, I usually shoot real estate videos so i definitely don't want this happening again, fall onto a house. The battery is a little puffy, im going to toss it, didnt notice it before the flight but i dont remember if i would have noticed. (just doing some research and this battery is the only one I own that doesnt say v2.0 on it and im seeing reports of swelling on the v1) Are there any logs created that i can check or im just out of luck? Im thinking battery because I lost signal to my screen before it hit the ground. Im using a phantom 2 with a h4-3d gimbal, I bought it as a kit bundled with: 1 x 5.8 Ghz Tx Video Transmitter System 1 x 7" Super Bright LED Outdoor Monitor with built-in DUAL DIVERSITY RECEIVERS , Built-in Battery, and Battery Charger 2 x 5.8 Ghz Omni-directional receiver antennas 1 x 5.8 Ghz Omni-directional transmitter antenna 1 x GoPro to Video Transmitter Cable Thanks for any help.
