thanks a lot ,i had used UJR & vjoy make gas and clutch as a single axis..it's good for me..
it's strange when i only plug G27 and with nothing set just use my KB Rctrl+; , . /
the Su33's trim light worked fine....but the stick still don't move any more....
i don't know how could nothing happened but the trim light turn off mean the trim should be worked T_T
