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
You can take a chain saw chain and push out one pin. Then fashion ends to
the chain. Pull it up to the branch with your rope and then pull back and
forth to cut the branch. They actually sell these commercially, they have
a very light line with a weighted bag on the end of the heavier rope.
