For more aileron throw, here's an FAQ that outlines one approach (the preferred approach):

Another way is to edit the servos (Servos tab). Make the control horn longer.

I like the method in the FAQ because the editable parameter is the max deflection in degrees, whereas when tweaking the servo control horn length the max deflection comes by trial and error.

Glad to help here. I think our tech support approach is to cover what we can here in the forums, and then Horizon/FSOne has their weekday toll free support.
