Fluttering and high speeds.

[Ruedii]

When SAS is enabled, I noticed that some of my rockets severely flutter at high speeds (In excess of Mach 3). If I turn off SAS, or revert to stock SAS they tend to work fine.

I am suspecting there may just be another conflict between MechJeb's SAS enhancements and FAR, this time causing a control feedback loop into the hypersonic range Mach effects. The other possibility is this mod isn't quite correcting them all the way, even though it may still be helping.

To be clear, the flutter is far worse without the FAR Extension module . . .
