That was a great thread!
After reading all of of it through and watching/reading all the links, it seems like it makes sense that the whole ordeal, needs to have 2 identical rigs to cover overlapping the battery swap and tape flips necessary. You could probably do this with 2 tapers, hat-mounting, and each of them running a Nak 250 instead of its older brother. Definitely need a pass to get the gear in, but the whole thing could be done stealth pretty thoroughly that way.
Anyway, this is a totally cool way to spend some time!
