if its realflight and i think it is.. the serial number for the sim is on the controller.. you can download the software from thier website.
RealFlight coming with a Horizon model????? I don't think so..... lol
I don't remember what Horizon's sim was called, FS One or something like that? Any way they quit making it and is probably the reason the new PTS's don't come with a sim anymore. Horizon sells Phoenix now but RealFlight (Knife Edge Software) has always been tied into Hobbico.
For the OP; there were a few issues with the original PTS Mustangs, may 'wanna try the search engine here for some of the threads on that model.
