I think the hassles getting aerospace clearance would make it uneconomic.


It would be way cheaper to have the drone string some det cord. An old
ordnance guy my dad knew used to do that--works great at smallish diameters.

Pull the top of the tree over , as detailed earlier, then it would be
easier to use such cutting wire close to vertical action, much safer
than chain saw whirlygigs

That's how a pine tree near my house was done a few weeks ago. It was
pulled over by a machine. I haven't a clue how the pull cord got
attached so high up the tree.
