What's the flying time? Is it within the limits of what a round of SPMBT would be? Couldn't you just then create a UAV under an existing helo class and then modify its weight and the carry capacity of affected infantry so that they could carry it?
90 minute flying time. I've also thought about making it a helo class; but then that means it would automatically "run away" when it's routed or damaged, which doesn't really apply to an UAV, they're designed to be expendable.
