I use one of those. My setup was thrown together a big haphazardly, but here's my settings from config anyway:
[rts_joystick]
1X=0 78 84 88 92 95 97 100 100 100 100 10
1Y=0 47 58 65 72 78 83 87 91 96 100 10
1RZ=5 26 44 59 74 84 90 94 96 98 100 10
1U=0 100 100 100 100 100 100 100 100 100 100 0
1V=0 100 100 100 100 100 100 100 100 100 100 0
FF=0
See if that does you any good.
