Interesting to hear that your M11x shows the same kind of behaviour. I am actually considering to swap my Futaba for the M11 because I like the hand feel of the Tx and the rx unit is really small. Your report makes me think twice...

To me it is clear now that in HRS mode the failsafe circuit "senses" something that it does not like (could be voltage below/over a certain threshold or digital radio signal corrupted) and shuts operation briefly down. After a second or so it comes back alive and the car continues to run normally for a while...
