too much, so you would need a cable. The power supply could be to

lose focus/strength?

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


Indeed, easier to simply put a chain saw on a drone (really ducking!).

I would use a drone to loop a fishing line nylon, up around the tree at
required height, and down . Use that to run a rope around the same path
.. Bang a good ground anchor in the ground and winch the top of the tree
over. Then make some sort of running guide to fix a chain saw to a rope
and pull that up the rope while it is running, while I'm standing well
away of course. Require some extra ropery to get the angles and cutting
progress though
