Might be very useful. I reckon at the time you're going there will be every man & his dog travelling both ways across the Simpson. You could use a RC aircraft with cam to look over the dunes ahead for the 4wd's & bikes coming toward you without Cb's or flags. Seriously I reckon a lot of care will be needed as it'll be the busiest period & there's bound to be a few bozos who left their brain at home out there, & head ons on top of dunes aren't what anyone wants.
