1st flight betaflight 3.5 failsafe and loss. Not related to firmware.03:21

My firmware testing 4s rig (beater). 1st flight with Betaflight 3.5. Lost this rig with Gopro on Friday. Got it back on Monday. 🙂
Only 1/10 mile away, but when it went behind the trees and metal mobile homes video was toast.
