When I first got track IR I imaged I would be able to see better. Yes of course I could see better. I could effortlessly and naturally lean just a little to the right to look through the Revi as I line up a shot.
But the thing which I didn't expect from Track IR is the feeling of flying. When you do a loop you lean back and look up and over as you pull through ... If you are flying full throttle at tree top level at 60 degree bank you lean with the turn to stay upright and it FEELS like you are turning.
I think you can turn any web cam into facetrack for free. Try it
With track IR the revi is perfect on the right side out of the way until i need it.
One of the things they used to say to the new pilots is keep your head on a swivel.
