RE: Benefit of two aeileron servos - could i make this mod to DPS?
I'm not one to rain on anybody's parade, but I'm going to inject some reality here. If it's your first build, and you're asking the question, I would bet $100 that you will not be able to tell the difference in the air. The slight downside is that it does add some complexity, and something more to fail (the Y cord).
