today i went flying with a friend of mine in order to teach him the basics of multicopter flying. He flew around a little bit and when the lipo alarm began buzzing (3.2 V) i told him to switch to RTL mode on
the remote. The quad went home and about 6 to 10 meters above the ground (while landing) it suddenly started spinning around and crashed immediately into the hard ground : (. Two of the motors are damaged and the frame is also a total loss. Bevor i start any repair attempt i wanted to make sure what happened. Would you please take a look at the log file? For me one of the motors seems to have a problem but i cannot read anything more than this from the file. Could you verify this and find something out?
Thank you so much
