Can post a video or a few photos of this trick.
By far, the easiest method to relieve pressure on the lever pivot pin is to position the assembly somewhere in mid stroke prior to removing from the drone. The way I do that is start the gear raising, and pull the battery as soon as it starts to move. This is faster, easier, and maintains original alignment of the parts during disassembly and reassembly. Call this the "Battery Method".
However, it is not always desirable, or even possible, to use the battery method. In such case, you will need to manually turn the gears after disassembly to relieve the alignment pressure. Call this the "First Gear" method. That method is described in the document below, which also provides some general pictures to assist, even if you used the battery method to relieve the pressure.
Apologies for the rushed look to this. I didn't have enough time this morning to do much more than get pictures and add words. I will try to clean it up sometime later, and update the post with a cleaner version.
