RE: Difference between OS 46 fx, and fxi?
The way I heard the diff. to be between the .46FX and the .46FXI, is that the "I" in FXI meant that it was already "run in" and required no run in before flying, thus making the NexSTAR truly RTF. I may be wrong but that is what I heard. I have the FXI, FX and AX and they all seem to run the same.
