Today I went for the new experimental version (no longer a mod, it’s a standalone plane now) and it completely alleviated the oscillation issue for me (I was running stable ver. yesterday). Night and Day. This thing is just awesome, I get no unusual oscillations whatsoever now, and I can finally enter mach speeds in the FCU. Now the only thing I’m waiting on them to implement is the Constraints (CSTR) feature to the MCDU for speed and altitude.
