Facts.
Drones which can achieve more than a garden distance flight away costs $1000 and up. SO a few pounds model will only get you a few meters away.
You cannot see them at more than 300 meters distance even with binoculars so the ability to see one at 2 miles is not likely.
Anything larger than the size of a football and the costs spiral upwards very rapidly. Way beyond any chav's means.
