Lockstock
It's been a while, but if I recall correctly the RPAS course was about 40hrs in Grob (including solo), about 90 hrs in the Tucano Sim and a live flight (and a mini IRT), thence to USA for their UAS Fundamentals Course (about another 60 hrs of sim RPAS flying) then a Predator or Reaper Formal Trg Unit (read OCU in UK terms) for a bunch of live flying and sim flying. Again, if I recall correctly they had slightly more hands-on time than a Multi-Eng RAF student pilot and more than a CPL frozen ATPL.
As I said before,
de facto pilots...Piloting an aircraft through the sky under IFR with a fly-by-wire wireless cable about 8000nm long!!!
