I couldn't tell in the model instructions what the control throws were supposed to be. That said, the diffrential for my deltas has only been a issue when I wanted to do repeated rolls and stay in a straight line. Other wise after the third or so roll it starts to kinda do a barrel roll and not on the axis of the model. Normally I don't worry about diff. The biggest thing I would thing about when progaming the Tx is how much throw for each action wether ail or ele and then dial in some expo (I like 30%) to make things a little softer at the center of the stick.
