RE: Rudders
don't necessarily need them with the X52/X45.
The X52 stick will twist iirc.
The X45 has the rudder option on the throttle - like a rocker of sorts that works fine.
RE: TIR5
There are 2 ways the camera gets input. One is with reflective tape attached to a metal thing that you sit on your ball cap. (if you're like me, you lose the metal thing and place 3 pieces arranged in a triangle and pasted to your forehead - works to ward off random children, cute chicks, UFO's, and the occasional black helicopter).
The other way is with the clip - which the camera picks up the 3 points of light/energy/photons/magic fur/whatever.
You get more precision with the side clip, but the hat thing works fine in most cases.
Get a TIR 5 regardless the costs.
