How to reverse servo out put in quad copter mode?

I am working on a project that uses servo controlled puffer jets to stabilize the aircraft, but in quad copter mode you cannot change this setting, I was going to use a Y harness to control both pitch and roll puffers but as you increase throttle it would close one puffer and open the other. I used all 4 channels and it fixed the problem but now I need to reverse one roll and one pitch servo how can I do this, the software does no allow for this.

Hi Ed,

I’m not sure exactly what you want so perhaps a servo reverser might help.
