Where do you get that part?  If you crash and break it, where do you get another camera mount?

That would be really easy to fabricate in metal so that it couldn't break.

I set 2000° deg/sec.  So I tried in horizon mode real quick.  I had gyro set instead of setpoint.  The computer got confused, couldn't stabilize.  I lost a motor on the 2205.  I've ordered 2208 and backed it down back to 1333° which was stable though I need to run test again after.  I assume the motor hit the fence on the way down so I lucked out nothing else bust or it landing in another yard.

That sounds really unlucky.

Looking at the telemetry it was a combination of the computer being confused and lack of throttle input.

2000° deg/sec is just too much.  No one really does that.  The reliable limit is around 900° deg/sec.  When you engineer stuff on your own and have the capability to go above and far beyond the safe limits, you are on your own.  You should've seen what happened when I put too much power on my RC boat..  What has happened never ever happened on any internet video.

We can safely stay within the limits like a DJI drone and never ever crash but that is boring.

Definitely user error on my part but the I term relax was set to gyro instead of Setpoint.  I had good luck with it before but the deg/sec was lower.

How much damage did the drone suffer?

The front left motor wire inside the motor broke.  Going iFlight XING 2208 2450KV.  They were emax 2350KV 2205s from way back.
