iPad X-Plane--OBS knob on the CDI spins airplane

[breadwild]

Per Cameron I'm going to ask a question about the iPad (yes, I have the desktop version, but my wife doesn't want my whole computer in our bed...that's an attempt at humor).

 

Anyway, when in the latest X-Plane for iPad, when I try to adjust to the OBS knob on the CDI to line up the needle, my plane goes in to a death spiral. What am I missing?

 

Thanks!
