Hi guys. I have the exact same problem. So I was cruising down the road at top speed outside line of sight when a tree branch reached out and *****-slapped me P3. I ran down the road to find my quad in the ditch minus a camera. After a quick search, I found the camera 5 yards off in a driveway. One of the gimbal arms and the ribbon cable were dead.
I found a repair kit with gimbal arms and ribbon on amazon. I took the gimbal apart and replaced both arms and ribbon cable (only needed to replace one but I had it apart so..). It was a little hectic at first but I got through it. I turned it on, linked it up to my phone, and started fiddling. I got a good image from the camera and the drone started right up but I have been unable to get ANY movement out of the gimbal! There was a warning or error or something but I can't remember what it said. I took it apart 2 more times now to make sure I had all ribbon cables properly seated (yes, this includes the 2 gimbal motor ribbons as well) with no luck. I don't even get the gimbal happy dance upon start-up!
Please, can anyone help???? How can I fix my baby!?
