Now, you can use a fiber optic switch to do the same thing, but it ties up a channel on your receiver and it has the exact same effect as a throttle cut. Its just adding yet another step that can be done just as well without it. I suppose the only thing the optical version protects you from that throttle cut cannot is throttle servo failure. With the optical switch if the servo fails you can still kill the engine.
That is all good and well.... as long as the throttle servo is functioning!

Agreed as I mentioned at the end of my previous post. Its a relatively lightweight option to add so its not a big deal to add it in there. There are just so many things on these planes that can fail, heck all of it can fail. Servo arms fall off, servos fail, linkages break and bend, batteries fail, regulators fail, servo extensions come apart, engines fail, wings fail. Granted, this is a way to take all the business out of the business end of the plane so it is a practical option with no real penalty other than a few extra bucks and a channel on your receiver tied up.
