I respect your opinion as an opinion. I have not, nor has my enterprise dealer, heard of a 600 crashing over a single motor or propeller failure. If I do I'll post it here...I'm not dealing with legents.
If you stay in this forum only will probably never hear about other things related to m600 as this one is mainly oriented to inspires. There are posts in the dji forum on that matter as well there was one youtube video but I don't have the time for diging them out. You can do your research on that matter. The main reason for their fail was broken screw in the folding prop.
