I have a JR10X, I used to have an 9ZAP and it was not difficult, first set the amount of mix start abut 50% then the offset will be set while you feed elevator input , i.e, 50% elevator input then push the offset key to mark the start point of spoileron movement.Anyway that's part of the hobby I like to find out about new program features, and you said it about the amount of features a radio can have, I think that about 60% of the computer radio user only use ATV, Subtrim, Expo and D/R. Good luck!.
