Just to be sure that its the stick and not the game, be sure your either in a fly by wire aircraft, or that you have your aircraft trimmed propperly. Also make sure your totally patched up; as the "smooth" option slider in 1.1 is broken on the axis, it is corrected in 1.12a available here.

I have to agree with Buzz, flight sticks are generally somthing of a personal preference... personally I started with CH products but found I was replacing them every year or so due to normal wear and tear... then again I try to put in a couple dozen hours a week on the sticks. Since then I have moved over to a Saitek X45, although the X52 looks like a nice second choice it dosn't offer (me) the same feel that the 45 does; as the 45 can have the spring set pretty tight and the 52 "felt" a little cheap. The STT programming software for the x45 works fairly well opening up quite abit of compatibility to alot of titles, plus mode selections exc exc... offering alot of keyboard functionality to the stick. I.E. for lomac I have an air to air mode, air to ground mode, and Air def/Nav mode which changes most every key bind on the stick with a flick of a toggle. Product support is not quite as good as the CH stuff, for example, to do a lomac setup you either have to hunt for a file, borrow one from someone here, or create your own (expect to take 2 hours to do this). There is some incompatibility with some titles that usually has to be patched out; due to the way its setup on the USB (dont want to go into it) but you see this on games like "planetside". As far as CH goes I am interested in picking up some of there rudder pedels before the end of the year. I think most will agree though that CH and Saitek both put out quality products, its a matter of options and what "feels" right to you, I would suggest a trip to Frys or Bestbuy and put your hands on some before you order/buy anything.
