My question is, Why?

Interesting to watch, obviously a very skilled pilot. But what happens when drop line fouls in a tree, or the saw stalls part way through a cut and the operator is left with no option but to jettison an expensive piece of kit?

How is this saw able to cut through a tree in 1 second of contact? Presumably it is spinning incredibly fast. How does it avoid gyroscopic precession?

[astroscuba]

Possibly has two blades going in opposite directions to cancel the gyroscopic motion?

Maybe they sell the cutoffs as Christmas trees.
