Quadrotor rollover

Hello!Today, the flight tested four rotors and eight propellers. The first two flight normally, and the aircraft rolled over during the third flight. Please analyze it, friends, thank you!

It’s hard to tell, it looks like there was stick input causing the roll before you got off the ground. But also there’s no motor/ESC logging so it’s impossible to tell if there was a motor or ESC failure from that log.

Stick to one post for the same problem. Cross posting will not help you.
