I was taking off in the TBM 930 and on rotation I noticed the aircraft dip to the right, so I corrected the dip and retracted the gear, pitched up to maintain climb speed and raised the flaps all while using 3/4 left deflection of the yoke to control the roll. What the hell is going on here I’m thinking? I’m going to have to circle back and land, I scanned the cockpit, AP not selected, but I cycled the AP switch just in case, looked down at the MFD and the aileron trim indication was 3/4 to the right, how did that happen? Selecting the trim buttons had no effect (This was a mouse select problem) and I couldn’t remember the button config that I had set up on my yoke so I did my best to get the aircraft down, but realised that would probably end badly, so paused the sim and checked how I had the aileron trim configured and set the aileron trim to neutral and all was well.
I use a generic checklist for most aircraft and it sits on my yoke, and it lists “Check Elevator Trim” so out of habit I do that, but didn’t check aileron trim and that probably would have ended badly in real life for me as it has for others. I have no idea how the aileron trim was moved, I don’t really ever use aileron trim much and it’s never happened before and hasn’t happened since, but it taught me a valuable lesson.

Most probably an unexpected control assignment - I had it with the “cockpit reset view” command (space key) that had additionally bound “rotor brake” - not so nice when in flight. Luckily I wasn’t able to gain altitude at all, and the strange rotor sound made me check all gauges.
So lesson learned - before flight check list in FS2024 has to include “open controller assignment window and check for correct settings”.
