That probably is the reason why it's still only a concept. ScanEagle is good because it's cheap, it's a simple airframe with a really good set of optics on it for 'eyes on' situations.I will confess that I don't really understand what the target market is for this concept. It's size limited payload is just a mini gun and a pair of hellfires, that suggests to me that it is intended for the counter insurgency market, but it's an LO airframe, and a small one at that, which means it's probably got a fairly short range.
I think it is too small to be particularly useful.
But VARIOUS?
Seems just a bit crap IMO. Factor in the cost of developing it and i'd rather not.
