Not really, but you have the flight time in telemetry and the motor status.
Real flight time, where the motors are running, can be identified by flight mode (all modes except 16, emergency (12) and calibration modes (10, 11)) or by motor start/stop in Remote CH0, value zero (CH0 in flightLog = Ch1 in Channel settings). Motor Status says, which motor is on and running.
This is valid for all Yuneec copters + Blade Chroma except H520. H520 is another SW family with completly different FlightLogs.
