Something that stuck out to me:
The AeroScope signals are not encrypted, despite what we wrote in a previous version of this post — even though DJI and an independent source both told us they were encrypted, and DJI insisted they were when we did a fact-check, DJI now admits that they aren’t encrypted at all. So they could be picked up by other kinds of receivers.
Depends on where you live.
Florida? Probably not necessary.
Northern Canada? Gotta get thru the waist high snow from last night that the plows didn't bother with. 4wd and some ground clearance is a must.
