Thanks guys, I'm having a blast in it at the moment. Helios on the touchscreen is a whole new dimension of awesome.
I don't see how three monitors would bring a large difference to immersion and aircraft control with the availability of TrackIR.
With that set-up vsempizdetz you can see that it gives you peripheral vision looking forward and the TrackIR would still work perfectly when you look to the sides to locate your targets

David is quite right vsempizdetz. I've picked up missile trails, tracers, targets etc on the side screens that I would have missed without the peripheral vision. Also it allows me to make the TrackIR pan a bit less sensitive, as I can turn my head further and still be able to see the side screens.
Is that based off an Akers-Barnes with an Aces replica?
Exactly right. It's SpeedOne ACESII design, with a (working) navy ejector handle of my own construction (basically garden hose and electrical tape). The Akers-Barnes design is modified (wider, longer, higher) to fit the ACES. It doesn't often come to pieces nowadays, but when it does the whole thing fits in the back of my Subaru for flight sim expos and so on.
