Looks like DJI finally smartened up and installed a steel plate at the rear motor joint. Now, instead of a steel shaft press fit into soft aluminum, it looks like steel pressed into steel, a much stronger bond and better design. I am basing this on a photo I saw of a brand new replacement camera/gimbal. I have not seen this up close or taken one apart yet to verify it is what I think it is. Anyone else seen this on a new camera or quad or have any info to add? If this is what it appears to be, the separation problem should be solved for the most part, and the new design should help dramatically or eliminiate the out of level camera(after crash or hard landing) issue. EDITED TO ADD: Confirmed this design change with DJI today. The metal disk is embedded into the aluminum arm/housing for a proper motor shaft pressed fit connection, eliminating the separation problem. The other two motors have always had a similar design, they use a stainless steel housing where the motor shaft is press fit into it. I have seen zero crashes where either of the other two motors separate at the shaft joint. Time will tell, but my guess is this will gradually eliminate the market for gimbal protectors/brackets.
