I think I'm still a bit confused. The drawing (as shown) seems to indicate equal throw for up and down ailerons. Don't we want more up than down? Do you set the end points to enable more up than down? Sorry if this seems obvious, I just want to be sure. Also, you all use a Y-cable to make this happen?

Thanks guys!

Edit: One last question: what does dual ailerons do for you that a single does not? Logically, it seems you've got considerably more control... but a properly configured single seems like it would do just as well. Thanks again!
