I just checked what I claimed a little earlier. Yes, you can configure the Xbox Wireless Elite 2 Controller on the PC, and these changes then apply to Aerofly on the iPad. Since the vertical axis swap change in iOS alone didn`t really work, I changed that setting on the controller connected to the PC. Also, I changed the input curve for the right stick to "delayed". This changes the input so that I can now make very, very gentle steering inputs which help especially in the helicopters. Max value is still the same, the curve is dvidided into three sections: first normal rise, then a more shallow rise, at the end pretty steep, but that`s where you would mostly want full deflection anyway.
Also, the additional four pedals are by default assigned to the A-B-X-Y buttons, so I have an alternative gear operation button.
Together with the adjustable friction of the sticks, swappable sticks and it`s general much better built it makes a real cool controller for Aerofly on the iPad.
The desktop software needed for that configuration is just called "XBox Zubehör" (Xbox accessories), and you need to connect it via cable to configure it.
The Y-Button (PS: triangle?) still seems unused is Aerofly mobile, as are the stick and menu/start buttons, right?
