I have had an extremely frustrating day with my Phantom. I finally got the Zenmuse gimbal today. Its apparently version 2, but I'm not sure how to tell for sure. I used the upgrade kit. In my opinion the instructions/videos were horrid. Why can't DJI make a video that shows how to do an upgrade using the upgrade kit? I ended up finding instructions in this forum so that was helpful. It turns out that after installing the upgrade kit, installing the gimbal isn't that hard, but its not clear at all what do do in the video and which steps you can skip. Also the mount for my gimbal looks different than it does in the manual and the process for attaching it was different. This took me like an hour to figure. I never did find correct instructions online - I just had to figure it out on my own. Finally, after re-assembling everything, I noticed that the level on the controller wasn't working, so I took the control back apart and noticed that pot was damaged and so it wasn't turning because it was bent. I must have damaged it when installing it. I tried to bend it back but not the controller is dead. I'm just so frustrated with this whole process from the delays, to the "plug and play", to the poor initial logt of gimbals. I haven't decided if I'm going to try to replace the controller or sell it. In any event I'm frustrated.
