Even if the thing is being controlled in realtime, Baldock (Ofcom) have remote monitoring heads all over the place down there. If they can isolate the signal from the command unit then that presents a nice, juicy target for a bit of triangulation.

Those toy drones like the DJI Phantom operate on similar frequencies to wifi networks so you'd be lucky to get more than a mile or so range from them.

If this is a professional unit as the reports suggest then it'll probably be operating on the de-regulated short range device frequency allocation around 458MHz. Maximum legal output on that band is 100 milliwats which is more than enough for 5-10KM. You can even buy illegal radio units from those online Chinese junk marts which claim 20KM+ range.
