A drone is an unmanned aircraft for towing targets or being a target to shoot at. Reaper is Combat ISTAR; a very big difference. What you've just said above about the "RAF's only drones before Reaper and alike" is like saying a Tanker is Fighter or a Helicopter is Strategic Airlift!
Towing/Being a target in a range for target facilitation is completely different to providing long-range Armed Intelligence, Surveillance, Target-Acquisition and Recconaissance able to operate on or ahead of forward line of our own troops.
Don't fall for the media clowns that seem to think that unmanned systems are just glorified model aircraft - because they ain't!

PS. The other thing about the Queen Bee was that it was optionally manned - I know because I've flown one of the last ones at RAF Henlow. It is basically a wooden Tiger Moth.
