Hey, I'm having a similar problem. When I first launch the flight sim (In my case P3D V2) and choose the default plane (in my case, a Cessna 172 that I imported from FSX), the 2D Mini Panel won't display. What I've discovered, however, is if I first launch one of the bundled planes that came with P3D V2 (for example, the Maule), the 2D Mini Panel works just fine with the bundled planes. Then, when I switch to the Cessna 172, the 2D Mini Panel "magically" starts working again. I'd like to figure out how to launch the flight sim without having to do this song-and-dance each time. Any insight into this issue will be helpful.
Thanks all!
