I am here to be the newbie over his head in arducopter. I recently had a low altitude incident with my heavy lift LiDAR drone. I hate to ask, but my experience with logs is very limited and could really use some impartial eyes to have a look-see and maybe identify the root of the issue.
Here is a link to the log file
I have intentionally not provided much flight info in an attempt to get the most objective results. If details are required I will gladly give them up. I also have PFV video of the incident.
