Ah, I would have thought it was more like "feedback loop" going to "feedback loop with DSP" going to "feedback loop with DSP with wireless" or similar. I think

Ah, I would have thought it was more like "feedback loop" going to "feedback loop with DSP" going to "feedback loop with DSP with wireless" or similar. I think I am thinking more specifically about the flight feedback example compared to what you are describing, but I'm definitely all for using cheap powerful ARM chips in place of obsolete stuff. I'm just hoping that most of that spare computing power was used for something cool and not just spinning the wheels.
