jpwpq8,
In answer to your last question, the UCanDo is in the G3 Expansion Pack. You'll need to have the Realflight G3 sim to get the basic software and the RealFlight controller (it's a TX made by Futaba and made to work on your pc without any batteries or anything else), and then you'll need that Expansion Pack. The expansion pack has a bunch of new airplanes and photo realistic flying fields in it, so it's worth it.
