So ran engine in the plane today and turned off the radio while the throttle was a few clicks above idle. The throttle came down and it seemed like two seconds and the engine shutoff.and then it went into cool down. Display did not indicate failsafe but it should have been available to see as is explained on page 64 of the manual. I didn't see that in the manual until later after I ran the engine one more time and powered up the plane a few more times so it was too late to look for a failsafe indication.
