Has for the TIR5 the 4 or 5 will do as excellent job. However keep away from 3 it's more fiddly as i always found my self always setting it up to were \ how i was seating were as with the tir4\5 once setup and got your settings how you like them you don't need any changing. and BTW TIR support is the best you can get.
Once you used a TIR4\5 or even 3 your in game flying driving will never be the same just watch out for feeling sick while using them for the 1st week or so as it makes some people that way.
