Installation was pretty straight forward, the panels information automatically added itself (I use FSX 2 P3d tool). The only manual thing I did was copy the gauge into the prepar3d\gauges folder.

Well, I started prepar3d with my ipad and airtrack open, but nothing happened. What am I missing here?

Well, I was missing a very important step, which was selecting FSX on 192.168.1.7. Resolved.

:) Yes, it is not always obvious that you need to tap on it :)

Glad it works,
