Let me also thank Ghost officially for this tool.
If you have an IPad you should try it. The cost of buying the TouchIR App + Upgrade (around 5€) is good spend, because you can use that App to make yourself buttons for any other sim. Pretty practical (similar to the multifunctional panel from CH).
Ghost put a lot of effort in making working buttons and a nice background for the IPit.
I really hope, one day there will be also live functional CDU and MFD screens, so you don't have to look for the button on the IPad, then look to the screen, then back to IPad. Would be awesome. Anyway it is a great start for this App.
