The trouble with these guys is, you never really know how bad the slit is inside and exactly when its gonna go when you're cutting it. Yes you can take precautions, but if the middle is mush, she'll wanna go sooner than you think, since there's less solid meat in there to hold it together. I think I'd do something like Skeans said, and drop a bigger tree on it after making some test cuts, but I really like the tannerite idea!! Does your drone hover by itself? You could set that up in the air along with your ground filming for the full effect!
