Regarding feeling dizzy watching those videos, in my experience it is to some extent dependent on the fact that the tool he used to record the videos, fraps, takes away some fps and thereby makes it a bit more jerky. Also, when you are actually in control of the head movements you don't get dizzy like you do when you passively watch the video. It's like when somebody sits next to you when you play a fast moving game like Battlefield or driving Colin Mcrae - they also get sick while you don't notice anything. Once you get used to Track IR, it's a walk in the park.http://www.alcom.aland.fi/kitte/pmdg/spitfire_ksan.wmv

Ya I know its great, thanks for trying out the TCAS.(To my knowladge the TrackIR 3 and 4 use the same software, so the profiles are the same. If you can find a way to send a profile, i'll buy you a cookie!! (not that xmas hasn't brought on enough of those...;) )Muchos gracias para la ayuda

Definatly the DF 727, a truly AMAZING package. And about the TCAS question, unfortunatly it does not work with VATSIM out of the box. but i believe there is something out there that can make it work. check out the DF727 forums.Adam
