I do not have the capacity to do the numbers but I have been thinking for a while that a helicopter with an electric transmission may well be a viable option real soon now. The next question is, does it look like a helicopter or a say four (or more) fan drone?
If the latter, no more Jesus nut, no more single points of failure (close anyway).
Option to consider a smaller than otherwise cruise engine with battery boost for take off, landing and emergency use.
Or maybe it's too soon?
