The Australian rules for turbines require a radio controlled method of shutting the turbine down independant of the ECU as well as a manual shut off valve.
I use this arrangement to do both jobs.
The servo is also set up with the failsafe to shut the fuel valve.- John.

Its the same in the UK and most of Europe. I use a manual festo valve before the turbine. On my on TX either pulling the trim down or loss of signal and switching off the fadec will kill the pump. In addition, I use a one way switch to the pumps power lead, so by servo in the air or by hand on start up in the pits, I can kill the the pumps power instantly. The switch is one way to be manually reset only. It looks as if this type of setup might have saved some models becoming crisp and well done.
