[FAR] Static Analysis stable - obviously isn't

Everything is green or white across the board in static analysis from mach 0.35 all the way up to ~5km (and it's stable at mach 0.26 @0km), but the aircraft is have serious stability issues during takeoff and shortly after - particularly when SAS or FAR's SAS equivalent are turned off.

With SAS off, the plane starts to drift left on the runway, then yaws and rolls left. If I turn SAS on, I'm able to take-off fine, but then I start to get yaw oscillations and any kind of turn or yaw makes the aircraft unstable. I'm not really sure what I can change to fix this.

Maybe the tailfins is doing that. Did you try with sas off? Or, do you have enough air intakes?

[Boersgard]

Air intakes are fine, tried both SAS on and off.

It did turn out to be the tailfins causing the issue. I went back to the classic T and everything's working pretty good. Still a lot more instability than I'm used to without FAR, but I'm not sure if that's poor design or just how FAR is.
