CH Pro Throttle USB -- twin engine planes

[FBScud]

I've got things pretty well set up, everything calibrated in Windows, then in AH.  Stick and throttle mapped, rudders working fine.  The only problem now is that my throttle won't properly control twin engine planes (haven't tried four engines yet).  As soon as the engines get up to speed, the plane turns circles on the runway.  When I advance the throttle, the two needles in the manifold guage go in opposite directions.

Any suggestions?

BTW...I've tried mapping the throttle to throttle 1, then to all throttles in the stick set up.  

Thanks!

You have to invert the throttle via the box on the joystick set up screen, just the 2nd throttle tho. Its on the same screen as the roll, yaw, etc selection...

That did the trick.  Thanks!!
