He deserves a reward for keeping a sense of humor in spite of losing a jet because of a radio system that failed to perform as advertised. XPS has proven itself to be grossly inadequate as a remote control system.

Want to talk about stupid? I saw an incredibly idiotic comment on another forum about how XPS is a fixed channel system just like Spektrum, as if that made it just as good as Spektrum. That is precisely the problem with it and why Spektrum uses two channels and two receivers, because that works and what XPS does doesn't.

I use Spektrum because it works best. It is the only system designed from scratch specifically for RC. I've talked to people at Spektrum familiar with the design phase. They looked at frequency hopping schemes and rejected the idea. They found the dual channel dual receiver system just works better. I have also talked with high level jet flyers and turbine people involved in early flight testing and evaluation; same conclusion, Spektrum works better than any other scheme.

XPS, in spite of what they advertise or claim, apparently operates on a single frequency with a single antenna. Ever notice that all wireless microphone and guitar systems are dual channel, dual antenna true diversity systems? Even that stuff uses two channels, not single channel or frequency hopping.

WARNING:

If you fly an RC airplane with XPS there is a very high probability it will crash due to the inadequacies of the radio control system.
