No, I think you're right, I believe that the 127 is Futaba's main-line PPM RX (or is one of them anyway). I just don't think that this receiver is very "tight" for lack of a better word, in maintaining good contact with the TX in the midst of any significant interference.

From what you described, you were having an issue with an outside interference source and you need to try and figure out what was going on there (I don't believe it was the radar either), its just that from what I've heard and my experience, the 127 will have issues long before the Futaba PCM stuff will...

I don't have 16 planes (wow!), but I do have more than the number of PCM RX's I have and so I do an RX swap when I need to. The acquisition of the DX6 will help that tho as the 148 that was in my TRex will be coming out in favor of a DX6 RX so I'll have one more PCM RX to throw in the mix...
