Hi I tell you about the 4 problems I have encountered so far using the E90. As I have already mentioned in another thread, a micro SD card that meets all requirements but does not work. I mention it in the thread Micro SD problem. What Micro SD buy? The MicroSD card stays stuck in the slot from time to time. As if that little spring function that you have to press it exits does not work. I've had to pull it out several times by squeezing hard and using a thin screwdriver and pliers. Having installed the latest version 1.31 of the Gymbal, twice already take off with the camera tilted, with the wrong roll despite being the aircraft completely horizontal. It's only been happening to me since I installed the latest version. The lens frame support, where we screwed the adapter to place a filter, is loose. It looks like it can't be screwed into the base of the camera and I have a feeling it's stuck. Today the first time I put the adapter in place to put a filter and record the snowy landscape it turned everything around and simply pulling out the whole set, it is not necessary to force and it seems that inside it has residue like glue. Is anyone else going through any of this? What worries me most is the last point. It is not normal for everything to come out so easily, at any moment it could fall.
