drone won't start and constantly beeps
I just got a new DJI Phantom 3 Standard a couple weeks ago. Today I tried to fly it (probably shouldn't have it was really windy) and on takeoff it got pulled into a tree. As it fell the battery fell out and hit the pavement. I put the battery back in, but now every time I start it it constantly beeps and the rotors twitch, but it won't let me fly. Please help me.
