I have a Logitech Wingman Cordless Rumblepad. Using the Wingman software it is possible to remap any control to another control. So you can remap the left stick x/y axis's to the right stick x/y axis's. You can even remap the d-pad to any stick, or the x-axis to one stick and the y-axis to the other stick. In fact you can remap almost anything to anything. Doesn't your Thrustmaster software allow this?
If not, get one of these Logitech Wingman Cordless Rumblepad's. They're excellent and so is the software. Check it out. 13 buttons (11 programmable) including 4 front buttons and six top ones, 2 analog sticks, 8-way d-pad, variable throttle control, gutsy rumble, real comfortable adult-size ergonomics with no annoying ridges and everythings fully remappable. You can even set the wingman software to use different button mappings automatically when you load different programs.

They aren't as cheap to run as what you have (unless you buy rechargable batteries) although they are much better IMHO...
In short, I have yet to find a better gamepad for PC. I can't fault it anyway. Feels nice and solid too. Doesn't look or feel like a toy.

I've had mine for well over a year now, and it gets used virtually every day. It doesn't seem like it will ever die, but if it does, I'll buy the same one again.
If anyone does buy one, don't get the corded version. The corded one has less buttons and there are ridges in the design, the sticks have much thinner shafts, the buttons aren't as nice to use, and the d-pad is nowhere near as good either. The corded version is a lot cheaper, but it sucks in every respect when compared to the more expensive cordless version. :happy:
