George's piece makes interesting reading.
Indeed I am just asking which type of servo's are out there in those bigger fuel/noise converters. The last two years I was not into buying new high class powerful servos, so I lost touch a bit, that's why I'm asking.

Basically George is right. Why pay for extra if not needed. Of course I want only the best for my jets, but it is only so safe as the weakest component, and there is MORE in a jet as servos.
I think nowadays highclass servos all perform above a required level.
So if I am convinced the top(price) servo's will bring me more safety, precision or other advantage, no doubt, they will get in. But I am not going to buy just to "feel" more safe.

I selected Jetcat because of a good price/performance, but technically AMTs might be better.... so the same policy I use in my servo choice.
