There is some interesting stuff in this thread. My thought is that most modern full scale jets are designed with computer stabilization in mind. I am pretty much 100% opposed to a gyro in almost any model airplane, except for jets and particularly ones where the full scale versions fly using some type of fly-by-wire. I fly in precision aerobatics contests so I am all-for full pilot control of an aircraft. But if an aircraft is designed with known inherent instability traits it seems crazy to me to hold it against anyone for trying a gyro.

I don't fly a jet yet but believe that venture will start in the not-so-distant future. I have started thinking about a scratch built airliner with twin 120mm fans and might grab a 'little' edf jet plane in the mean time. I am sure I'd try flying it (the big one) without a gyro but I do plan on having one basically from the beginning.
