    Well I guess it's always a matter of when, not if. I had my first real crash this evening - I was flying under a branch taking a panning video of my house construction when an altitude "blip" resulted in the props getting into the branch. I tried to quickly stick down to drop it out but I wasn't fast enough. The props shut down and the MP tumbled down about 10 feet, bouncing off a dumpster in the process.

    When I retrieved it I feared one of the arms was broken as it was folded back in against the body, but it swung out into position with no issues. I visually inspected everything and there didn't appear to be any damage. I cycled power and was able to take off without any issues, but there was no video. I inspected the camera assembly closer and realized that at least one of the tabs on the vibration plate is broken, and the gimbal acts kind of wonky (it acts like it's trying to initialize - turns far toward the vertical arm and just sits there. It repeats this process every few seconds.)

    I suspect that in addition to the vibration damper plate being broken, the video cable and likely the ribbon cable is damaged. I've watched some videos on these being replaced but I'm hesitant to take this on, especially without being sure of the problem(s). Do my assumptions about the issue sound like they're on track or might there be something more sinister at play with the camera/gimbal system?

    Kicking myself for not keeping better distance from obstacles :(

    Sorry to hear about your mishap. I think you are correct in saying it is only when not if. I have been lucky so far.

    What are you flying? Maybe @Thunderdrones could comment on how difficult it is to repair.

    I crashed my MPP and had to replace the gimbal ribbon and the mount plate(one of the rubber vibration dampers was broken so I just bought the whole plate). Its not really as hard as it looks, I was kinda skeptical about doing my repairs myself but all went well and mine is back to like new condition. Find a good video that walks you through it. I would say you will be replacing both cables, I still had video so I didnt have to replace that cable.

    I shipped mine out to @Thunderdrones today. I didn't really feel up to tearing down the MP after watching a couple of the videos on replacing the cable. It looked more tedious than I felt like adventuring into :)

    Well, Rob will have you back up and flying in no time. He spent a lot of time talking me through my repairs and offering information. He is a great asset to the drone community.

    DJI quoted me around $500 to replace the core board they said was blown. I decided to check it out myself, and found a board for $200.00, watched a couple of videos and replaced the board myself . During this process I tested both the old and new board and found no issues with the old one, and the problem was a damaged connector in a ribbon cable. Repair went fine and she was flying again.

    The tedious part saved me $300.00 and I learned not to trust DJI tech as far as I could spit into the wind
