The "Summary" screen only will give you running info of the last four runs and an abnormal code line if something happened. I think at this point, I would need the ability to download the ECU data to my PC to see the failsafe although I will check the summary again and see if it kicked a code of the failsafe run. I don't think there's a list of codes in the manual though.
Yea, that's the issue - no confirmation as to what type of shutdown you observed. The Jetcat setup is nice, just turn off the TX with the GSU attached, and if you have it setup correctly, you get a nice "F" on the display letting you know that the ECU recognized the RX failsafe.
Next time I get out the Cougar with the K-85, I'll have to look at it and see what I can see. I did verify that turning off the TX shuts down the turbine, but I can't recall if I timed it, or if I looked at it in the GSU display. I do know I wasn't really worried about it too much as I fly that little thing in so close I'm not worried about failsafes - just making sure that the turbine shuts down in any case. A bigger, heavier, more expensive airplane though like your F-16, and I would be.

ps. Len, we all know the difference between an RX failsafe and an ECU failsafe - the question is, getting the ECU to recognize an RX failsafe. Older ECUs, with the exception of Jetcat's, DID NOT have a mechanism for recognizing an "out-of-range" pwm signal from the RX as an indication of an RX failsafe. The whole debate is how do you *verify* that the Kingtech ECU DOES have that mechanism.
