RE: OS FX vs FXi ---Is there really much difference?
G'day Mate,
I don't think there is any difference, the FXi comes packaged with RTF planes, I believe.
The FX is the older version of the AX, which does have slightly more power, & is possibly slightly quieter, but the FX is still a great motor.
A guy in our club had a ST 51, in his pattern type plane, had all sorts of problems with it, so he changed to a 46FX, & has won the last 2 pattern comps that he entered, & with no engine problems.
