Hi Pete, I have an interest in using RCv4.3 for ATC in P3Dv4 and was wondering if you foresee this as a possibility. I see that you intend to create FSUIPC 5 and was wondering, would a new 64bit version of MakeRunways be necessary, or would the current version work? For all I know there is a new scenery folder structure in P3Dv4 that does not play well with the current make runways and was wondering what the possibilities were. Of course I use several add-ons that require MakeRunways like STB, and FS captain among a few others. People don't realize how invaluable such utilities are, until they realize it. lol Thanks, Paul
