Here is another good video stress testing the gimbal

I had also heard of the gimbal going limp under excessive high loads, there are examples showing otherwise so its a bit odd. I have seen a few people on phantoms that have had them go limp and I suspect it may be something to do with the PMUv2. Seeing DJI have announced the new phantom board that does away with the new PMU this may be for more reasons then simplifying the install and weight reduction. Though after seeing the board I would much rather use that then need to have the PMU and Zenmuse controllers also inside the space limited phantom.
