A couple of things come to mind. Are you setup for electronic mixing of mechanical mixing?

If you are using electronic mixing it could be your swash plate settings are reversed. That is you are using a negative number when it should be a positive number.

Another thing could be that you have the arm on the wrong side of the servo and that would reverse your settings.

Also, if you look at the book for the Caliber setup pay close attention to where the bell cranks are located in regards to electronic/mechanical mixing. This is where I screwed up the first time.

Hope this helps.
