A Question

Hi Everyone!
Brand new here. Just found this site and I am stoked! Been flying heli’s off and on for years. The old eyes just ain’t what they used to be! Looking forward to trying APM on my heli’s. I have a question though. I fly a lot of older heli’s that have mechanical mixing. In other words they do not use 3 servo 120 mixing. The collective servo raises and lowers the swashplate without changing its level. The roll servo tilts the swash left to right, and the elevator tilts it back and forth. Is there a setting for this in APM:Copter? Also is there digital servo support?

Thanks So Much!
