I received a TrackIR 5 on Friday. It was supposed to come with the Track Clip Pro, but it was missing from the shipping box.

Initially it isn't as smooth as my Track IR3, but with some more tweaking, things should improve.
I haven't got a handle on the new setup and I'm struggling with the range of movement. Your virtual head can swival over 360* , very annoying and disorientating in a dogfight. I have it setup now so that atleast it pauses before jumping past the rear center position. I should have it sorted tonight, but I seem to be losing interest in flying. Hopefully the release of ROF will renew my interest.
