Evidence I don't have; I just wanted to add...I received a new DX8 today, and tested, got a 'glitch'. Due to incorrectly allowing the default framerate for my older servos and ar6100 rx.

Thought it was Hitec 'pollution'

Going back to the DX7...when I fly I can note aerodynamic discrepancies vs. (other) various discrepancies. (pilot error...lol) In all seriousness, based on my observation, someone's gotten a fly into the ointment. Without really knowing it. Cell tower signals. Although the rx's can filter sometimes they have to go 'hold'.
It's not outside the realm of possibility that some holds can receieve code.
