I've read really good things about Radar Contact and downloaded their 400+ page manual. It is very instructive and helpful form someone who is just learning the world of IFR.But, after using Voice buddy, I also like the concept of actually talking to ATC ... hence VoxATC.Could I get opinions from users on these two products? Learning curve, support, upgrades, framerate hit (if any), helpfulness of forums, IFR/VFR, etc?

I've done hundreds of flights with RC4 and find that it far more realistic than the default ATC. I was able to begin using it right away, but if you are not familar with ATC procedures, a flight or 2 with the tutorial should have you up to speed. Support has been great and most questions are quickly answered on the forum. I don't notice any frame rate hit on my aging system.One real plus is that I no longer have go-arounds caused by AI traffic - RC4 maintains spacing. I also like the optional use of the virtual copilot to handle the radios. It's realistic and lets you make a restromm break during the cruise portion of the flight.The only drawbacks I have seen:-No help on taxi - I use FSNAV and figure out my own route, but this is more difficult at complex airports at night.-RC4 is strictly IFR - No real support for VFR flights, but you can always use the default ATC for this.-RC4 sometimes vectors you to the ILS intercept outside of the ILS transmitter range - this is done to keep you above the MDA (minimum descent altitude) surrounding the airport.I haven't tried VoxATC, so I hope someone else can comment.Dale
