Just posting to give an update to my last post. I took the gimbal with the slight vibrations out to take some video. It worked reasonably well but I wasn't happy to keep it.
3DR was having problems with their systems when they responded on Sep 21st. They issued me an RMA right away after asking for my serial numbers. I had included a video showing the vibrations at certain pitch angles.
Because of the system issues they were having, they couldn't issue me a correct waybill to take care of the shipping of the gimbal back to California. They advised I should pay for it and they would reimburse me.
Well we finally got some good weather and I was a little bummed out that I would have to send the gimbal off, wait for cross border shipping times and lose out on shooting, so I kept it over the weekend.
To my surprise, this week I got a shipping notice. Thought maybe it was my leg extenders - even if they weren't supposed to have tracking numbers? Well turns out 3DR sent out a new gimbal replacement for me right away direct from China. Didn't even wait for the gimped gimbal or charge me extra. Installed it today and it works perfect out of the box. No vibrating, no fuss.
Others have posted bad experiences, but 3DR really came through for me, despite the delays and issues. I'm really liking the product now that we have access to the gimbal. For sure, we're still missing some features, but I feel they are making updates rapidly enough for my use case.
