Please, can someone have a look at my log and let me know what went wrong?
At ~912 seconds, the aircraft began experiencing Speed and Yaw errors ( Basically a compass error ). The aircraft switched to ATTI Mode, which it is designed to do in the instance of a compass issue. In ATTI mode there is no GPS positioning, thus the aircraft began drifting in the wind. It looks like you were unfamiliar with flying in this mode. The aircraft continued to drift and you applied full throttle and hit the tree.
