I have been using a G-1000SDX to turn the C-3E/EF-240S combo for about 7 years,
and the C-3 alone for 3 years before that. No problem. The EF-240X is a
bigger antenna (longer elements) but I think based on my experience it will be
fine.
My EF-240S is above my C-3E, and I'd recommend going that route. At 6-foot
clearance I had to turn the 240 90 degrees relative to the C-3E to get rid of
severe interaction on 15 meters. Go at least 10, preferably 12-foot spacing if
you can manage it.
Incidentally, that's another advantage of the Yaesu rotator - I simply added a
second pointer to the direction indicator to indicate where my EF-240S is
pointed, and that was that. I hardly ever get confused before 4AM Sunday
morning in a contest!
