Default RE: Telemetry Flame-out Detector for Twin Turbines .. for less than $5

Hi Guys

I'm just in the throws of building my first twin turbine airframe and this thread caught my eye
Perhaps I'm over simplifying things but when the turbine shuts down it gets colder and the fuel solenoid would go from from 5v to 0v
My std Specy telemetry can monitor both voltage and temp, cant we just monitor one turbines temp and the others fuel solenoid voltage?
"Could we not use these two telematry sensors to"
If the right turbines solenoid shuts off voltage the drops from 5v to 0 so set that alarm to "tone"
Then if the left turbine shuts down the temp near the tail cone will drop very quickly, set that alarm to "vibe"
(Temp sensor range is -40c to 538c)
Tone = "Right engine dead"
Vibe = "Left engine dead"
Vibe + Tone = "Go get me some new pants!"
