The aircraft I fly does not have any normal CA markings as it is in US Army military colours ,but that's not the point.
I was really questioning the legality of flying below 500 feet if not nearer than 500 feet to any structure,people etc.
Reading the replies it appears that bearing the 500' rule in mind, it is legal to fly at any height in open countryside especially if over friends farms where there are no footpaths,houses etc.
