Just a note on your comparison - aviation engines/motors are not directly comparable to land vehicle engines/motors. They have different expected duty cycles[1][2] and thus, are designed quite differently. I believe the engines in an Apache are jet turbines, which may also not be directly comparable, but that's only a guess. They are also "war machines", and likely are built to tolerate abuses Tesla cannot imagine and do not design for (my assumption here is that is what adds quite a bit of weight to the Apache engines). All this is to say the obvious, one could not simply take a Tesla electric motor and install it in an aircraft, expecting good things. Things may eventually change, and ultimately you may be right - I just don't want to put that much faith, yet, into this idea.
