All I've seen in between then and now is some other guy giving instructions in a thread on this server but I haven't seen any official word on the actual kit since
Without wishing to praise the creators, the kit and instructions are really well done and assembly is simple! You can take a look in the dedicated sub!
When I say didn't see twist or brake axis, I mean any input on those axes wasn't picked up. I can see the thumbstick though. And the actual base's inputs.
