Sudden loss of control

Could I get some assistance on why sudden loss of control. It doesnt look like I ever lost radio contact (checked RIN against ROUT), or had brownout, but during about 1 min (or less) into flight, I lost all control. See accelerometer for actual time crash happened.

logs are attached.

Though I am noob, I have followed troubleshooting page and tried best to do this on my own. … sing-logs/

I found the issue. The antenna on my TX had been damaged thus was not getting range above 30m.
