Confirmed. Nor there was any actual use in reality AFAIK.

Ok I solved this mistery. I had to swap the axis in FF assignment settings. This was the reason why I thought my vertical trim trimmed alierons. Trim with FF Joysticks are actually changing the "zero" position (like in reality, simulating trim force on stick). This exactly reflects the real stick but if your system expose FF asis in different order than joystick axis, it will push the stick sideways instead of forward/backward.

Hey, the triming seems to be broken in my case too. What's even more weird, when I bind the mig21 trim to hotas, it seems to trim alierons xD yep I know how stupid this seems but plane is banking when applying a trim and my forcefeedback joystick is moving out of zero position to the trimmed side. More over, triming by keyboard bind seems to do something (the elevators start to move as well as the virtual stick) but after I grab my Microsoft Sidewinder joystick it resets to neutral position. Also, usually triming in other planes moves the force feedback neutral position (like on Mig 19) here it does nothing in case of triming by keyboard. In general I'm unable to trim by any way which would be working as intended... This is 100 reproducible in my case. It's not trim subsystem that is off. Does anybody else has the FF and can try the trimming in Mig21?
