Ahem...
Lets disconnect the motor wires for this.

Power everything up and throw it into idle up.
Move the collective stick upwards, the swash plate should move downwards.
When you move the collective stick down the swash should move upwards.
Is it moving in the opposite direction?
If it is you have to go into the mix CCP menu in the radio.
Goto the CP6 option and reverse the value, if its +50 then move it down until it's -50. That'll correct the swash movement.
Make sure that CP2 and CP3 are exact opposites, ie: +50 and -50.
Once you get all the servos moving in the right direction use CP6 to increase/decrease your pitch range.
