Good night to everybody!Well,I

1) rc controllers are live people who have recorded thousands of wavs, which are put together as rc runs. we think it is more real atc.2) in version 3, i know where the ai planes are, and i make traffic calls to them, and to you, when they are within the boundaries that require a traffic notification. but that is about it for ai interaction. in version 4, which is being developed as we speak, the rc controllers talk to all the ai planes as they progress through the various phases of flight.3) in version 3, and you turn off the ai traffic, there is canned-recorded chatter that can play, if you choose, to make the flight less boring. the controllers though, would only be talking to you.4) nav 3 is good, super flight planner is coming out with a new planner, and the fs200x planner does a good enough job in most casesjd
