Hi community,
The quadcopter just crashed after flown about a minute of flight. Can anyone guide me to get the reason for crash from the flight log.
Flight controller CUAV V5+ with NEo3 GNSS system on T.Drone M690 with 4S battery system.

You are running some old firmware. Suggest you update it to current Stable.
You have a problem with a motor or ESC. 3 of the motor outputs are close to max and one, Motor 1 is very low. Then Motor 2 hits Max (stops producing thrust), Motor 1 drops to Min and down it goes from lack of thrust. There is no ESC telemetry but possibly overheating on Motor 2.
And disable Replay so you have reasonable sized logs to share.
Thanks for the reply @dkemxr
The 3 motor goes high because the pilot given simultaneous pitch forward and roll left command continues.
I believe that motor 2 ESC will not overheat because it doesn’t have the huge payload and even flight time was just 1 minute when the incident happened after the takeoff.
Pilot said that one CCW propeller was missing after the crash and exactly on the motor2 . Meanwhile all three propeller were on the appropriate motors. That’s the reason I strongly believe it might propeller went out during the flight with its rotational forces somewhere away. That’s the reason pilot cannot able to find the motor 2 propeller.
