Default Rcexl kill switch good or bad idea

I recently had a throttle servo freeze up while taxing out to take off. I had the radio set up with throttle cut but with no servo that didn't work. I was able to run the plane down and stop it but it got me thinking about installing some kind of kill switch.
Today when I arrived at the field a club members was picking his plane up after crashing he said it was due to the rcexl kill switch going bad I don't know if that was the cause or not so the question. Is it a good idea to install a kill switch or not? It seems you only hear the bad things. I would like to hear your thoughts about kill switches.
Thanks
Dan

I wouldn't fly a gasser without one. I have hundreds of flights with RCXL 2.0 kill switches. Can they go bad? Probably, same as the receiver, ignition, servos, or any other electronic component. Is there a pattern of them going bad? Not that I've observed

I have one in each of my planes and they work well for me, great idea. I am aware of one going bad, cracked board, loosing contact. Replaced by seller no problem. Big planes require as many safety devices as possible in my humble opinion!

Gassers really need them, IMO. It's not as easy to use your throttle trim to kill the engine, and having the failsafe there to shut off your engine in the event of a signal loss is good.

Signal loss, throttle servo loss, linkage issue.

The problems it will save will be many more than any problems it might cause
