This isn't a flight sim, it's a RC Simulator. Designed for practise to simulate RC planes/heli's etc..
It's designed for the user to be using their own RC transmitter. I used to have a previous version of it. Photorealistic scenery has been around for years in these sims.
Does this look like an RC aircraft to you? http://www.youtube.com/watch?v=oGN35BeYkeE&feature=related
