Hey guys, the camp I work for had a Phantom 2 donated to the camp. Over the summer I crashed it into a tree and broke the upper plate on the damping unit, but fixed that. Ever since the crash the gimbal has been pulling to one side, the video shows the issue better than I can explain. I'm pretty new to using DJI products, so I'm not very good with it yet. I've updated all the firmware, and it is still happening. Does anyone have an idea or do I need to send it in to be fixed?   
This is the video                                                            

Pretty much means its done from my experience. I have never been able to bring one back once it starts doing that.

You will need to send it in for repair.
