On all of our X8 flying wings we are using APM2.5 and 2.70 firmware. Every day we perform several 40 minute long flights, after which we remove all batteries and charge prior to next flight. All of the days data is contained in one very long tlog file.

I would like to isolate each flights data to a separate file, for many reasons.

Is there a process between flights that I'm missing or is poorly documented in the instructions?

Thanks!
