A little more progress yesterday. I cross loaded a few of my favorite aircraft from FSX to P3D: C172 w/ floats, C185, C208, and the DH-6 Twin Otter. Unfortunately, I couldn't get my Ultimate Alaska scenery package to work and it doesn't look like the publisher is in any hurry to port it.
I'm also going to have to wait for EzDok v2 to release. The current version (1.17) "unofficially" works (with fiddling) but v2 will be a full release only, with no free upgrade for current users. I don't want to pay for it twice, so I'll just have to get along without TrackIR working in P3D for who-knows-how-long. Makes me appreciate how much it spoiled me in FSX.
