Yeah I had to rename my plugins folder to something else and put a new empty one to properly disable them. I downgraded back to xEnviro 1.07, just need to check to see if it's any better now!

This could be the issue. I would've thought the slider did something but apparently not. I'm going to try and reinstall 1.07.

Yeah. Right now I'm trying a fresh install of the tbm 900 with no plugins folder. If that gives the same results I'll reinstall X-plane. Uninstalling is frustrating because X-Plane is so big! And 'straya's slow download speeds + low harddrive space is a nightmare. Anyone have settings I could try EDIT/UPDATE: Tried with no plugins except for TBM(not a fresh install). Set weather to CAVOK. Aircraft flies beautifully. Now to reinstall each plugin to find out what it might've been.

I'm having this problem too. I'm running xEnviro 1.09(not sure if it's affecting the flight model or not). It's really strange it seems to be pretty random. It'll fly okay when it's straight and level but when turning and climbing/descending it bounces around like crazy. And once it's leveled out and normal it still takes a while to to calm down. Okay well now it's flying level and it's still bouncing around like a maniac so not really sure :/
