Hi Guys! Bit of an extreme topic title! i know the altitude restriction is 400 feet with model aircraft, I live no where near any air bases or airports, i fly to 400 feet above my home to take pictures. On several occasions luckily when not flying, helicopters pass over and I'm sure there within my flying area of 400 feet altitude. This is usually on the weekend. Im pretty sure its not police or air ambulance from the local hospital because of colour and model of helicopter. It appears to be leisure or business type flight. Where do i stand in this situation?
