I would really appreciate anyone who is already flying the FX-79 to post their PID settings, as I am having a heck of a time getting mine tuned in. Thanks in advance.

Indeed, turned out my issue was two fold. Too high of throws on the TX and had "use airspeed sensor" enabled in the parameters. Fixed those, and autotuned with no issues. Nav tuning could still use some work. I really wish I would have rechecked parameters before my first fully auto mission, on the last waypoint it lost quite a bit of airspeed and was turning from downwind into upwind, and got indicated airspeed down to around 9, and went into an unrecoverable death spiral. Min airspeed was set to around 10, shold have been closer to 20 with max at around 55. I'm thinking after all the crashes this airframe has endured, I might just order new foam, as this last crash took a decent chunk of foam out of the main body side, right wing screw down point. Not sure if gluing it back in will hold very well.

Are you able to share your PID values from automatic tuning procedure? I'd like to start with something useful and then hit autotune to only have smaller adjustments in air :)

Note that this was the mission with the tip stall crash I mentioned, so make sure to fix the speed settings.
Oh man, sad to hear ... death spins are quite an issue with flying wings ... have a look at this video: https://www.youtube.com/watch?v=nh8PbcFY_Gg .
