A new member with first post here. I've finished modifying RC controller for AT Duo ii. It is quite easy to unassembled the controller but had to be very precise on drilling holes as shoulder width of the RC is a bit narrow. I stick 3M Magic Tape on the controller so I can draw two circles where I wanted to drill holes and it would help if you practicing drilling holes in whatever piece of plastic you have to make sure that you drill exact size of hole for a male QMA supplied from AT. In addition, I've put
rubber O-rings under QMA to adjust for a slight slant of shoulder areas of controller to make QMA shafts straight vertically (see attached images). All in all it comes out better than I expected and I can use this controller for my mini 3 pro and Mavic 3.
