Avenger has a ~$15M per copy pricetag, compared to, supposedly, ~$30M for Reaper
That would be arse about face to me - an MQ-9 costs about $15M each depending on the spec of the sensors and weapons and I would expect Pred-C to be twice the price. But don't forget that a system is more than just the air vehicle; there's ground control stations, comms infrastructure and maintenance support. That said, compared to manned CAS/ISTAR, it's still cheap as chips as the more you fly the cheaper it becomes per flying hour.
On the endurance side it is very dependant on weapons load-out on MQ-9. That is no surpise though, I remember the drag index on the Hawk carrying 2x AIM9 and a gun pod and the Hawk T1A would be running out of gas inside 45mins compared to a clean jet doing 75mins.

Don't know, but as it is logged in a normal RAF log book (as actual) then I can't see how they differentiate? That said, it wouldn't do much good for multi time for an ATPL! Maybe there is up side to BAES' Mantis after all!!
