I think my Hood’s turned into a den of iniquity overnight - another copter, think it’s probably a police one, has been hovering and moving in close range for the last three quarters of an hour. Maybe last night’s was a police one too. It’s just gone, phew. It seems that sensors are all different, if only by a small margin. There’s always a short getting to know you period and a mental readjustment to accommodate the new one’s personality.
