Iris going crazy

Firstly post it in wrong section of forum, don’t know why, sorry to moderators.

Yesterday (now before yesterday) flight was strange. Iris didn’t hold at one place in loiter.
Try to disconnet/connect batteries and start again. Iris flew straight to the fence in loiter mode and broke last props. :cry:
I think its in last 2 logs.
Help me please to understand why its happen.

[color=#00BF00]No, you didn’t post into the copter forum. A moderator moved your post there because it belongs there because you have a software problem / log analysis, not a hardware problem :slight_smile:.[/color]
