RE: fail safe??
The JetCat ECU tells you how many failsafes you had during the flight (you can read it on the Ground Support Unit after flight). You can also set the delay time after you have a failsafe for turbine shutdown, that way you do not have any instant shutdowns, and maybe people will actually set their failsafe to sutdown (you would not believe how many people are not setting their turbines to shutdown on a failsafe!)
If you had one, and you had not been having any, I would check things over very well and do a very good range check like Lee outlines. If everything checks out, I would fly, but that is just me.
