I may be mislabeling the 127...these are the standard dual-conversion PPM RXes that come with a new Futaba system. NEVER had an issue with them before. Don't want to convert my rather large fleet to something else like PCM...we are talking some 16 receivers. If I had to do that, I would just wait a year or so for the next generation spread spectrum.
I also have Hitec receivers of several types, with no issues.

I really do not think it WAS the hardware at all, but something outside.
And it was like interference was switched on, then switched off.

The first plane was an F117, it's a very stable and slow flyer, it got hit twice, and I came down.
The second was a brand-new model for review, it got damaged pretty badly, it's a real pain, as I had not gotten flight shots on it yet, but repairable.
Third one was a Toki Sabre, I just ripped the rudder off and bent a few things, at least I did not total out three aircraft. I consider myself lucky. But also a bit stupid, as after two incidents, I should not have tried to fly the third aircraft. Obviously.
