i can only recommend track IR 5 Pro. It is way more stable when sunlight (IR-Rays)hits a wall in the background . The Immersion is massive, in GA as in Big Stuff. It was one of the best investments i made in fsx. If you have the Saitek Yoke too, map the on/off button and realign button to the clockbuttons on the yoke - very useful. I love the little device...
