Pitch & DesPitch mismatch ==> Crash

Hello, Guys,

As you can see from the topic, i had a crash and now I am trying to figure out why did it occur.
The plane was flying nicely in Manual mode, as soon as I switched it to AUTO mode it started loosing altitude very quickly, switched it to RTL - nothing changed, and before i could switched it to Manual again it was on the ground. All setup was the same as during previous successful flights, except for Radio Controller, we used new one. Since Radio worked correctly in Manual mode it cannot be the reason for crash, because it happened in AUTO mode. Probably it has something to do with bad elevator tuning.

Could you help me to figure out, what was wrong?

In the link below you can find Log files from the last flight:

Thank you in advance :wink:
