In my part of the world, very many helicopters fly around us all the time. From ambulances to construction aiding and what have you not. I see NONE of these in FlightAware, but most of them in FlightRadar. I know my site reports (some of?) them since I see them with SkyView.
All the explainations in the previouse posts make very little sence to me, since I reliably see them in FlightRadar.
Is there anyway FA could show them too? Maybe even as an option?
