Chris, if you don't mind me asking, how much was your TrackIR5 and where did you purchase it? I've had a TrackIR3 for many years now and am considering an upgrade but at over a ton to replace a working product, I'm not sure it's worth it.
True, a new engine would have more problems, but not the SAME problems. And you can't excuse everything by constantly saying "it's an Alpha". I too was expecting a new engine, and so far am just a touch disappointed.
