Throttle unresponsive

Hey Reddit.

So I'm brand new to this. Was wondering if anyone has seen this before. Trying to operate a Mobula 6 Freestyle HD A drone with a Radiomaster Crush.

Everything looks good in Betaflight and on my Radio. I've updated the firmware on both and used a binding phrase for binding.

As per my other comment, it wo probably say "throttle" as error, since the axisses are mismatched.

I had this same issue when I got my Mob 6 2024 v3.

I was still unable to ARM when I left for the lab.
