I switched from an old somewhat worn set of Thrustmaster F22 Pro, Tqs throttle, and rudder pedals to this new USB x36 combo Saitek throttle, stick,, and even the CH USB Pro Pedals you mentioned. As a result I left a stick set up with numerous button options and hats.
Originally I purchased it as the only USB set up available until CH products would release their USB equipment, but I was very surprised to find this Saitek x36 combo to be superior to my old Thrustmaster. It's smooth as silk, easy to program, has more button/hat options than you can find commands for, has an excellent feel in the hand, and has just the right amount of spring action.
Make sure you absolutely get the USB version. All the problems you heard about on bulletin boards were related to the old analog version. It's automatically calibrated everytime you boot up, and I haven't had any spiking at all. With Thrustmaster I used to have to set dead bands and dampers fairly high. I have my dampers set to zero with this Saitek, and my dead bands are barely off the bottom of the slider.
As for the rudder pedals I could barely take off in an F4u with my old Thrustmaster pedals. I had to have damping turned up, and a fairly good dead band which cuts down on the accuracy of your control. With the new CH USB Pro Pedals I have damping all the way off and only a small dead band. I can put the calibration cursor exactly where I want on the chart very quickly.
This is an excellent combination, and the only fully programmable set of Throttle/Stick and Rudders on the market. The current CH USB stick lacks enough programmable buttons/hats.
I have nothing negative to report about this combination, and it is very easy to set up with Aces High. The product will indicate that it does not work with stand alone rudder pedals, but it does in Aces High.
If you make the right choice and get this product feel free to download my Saitek Profile offered on the downloads page. It was given a lot of testing and thought, and it will get you started quickly. If you need help setting it up in Aces High with rudder pedals let me know. It's very easy, and I believe the read me file attached to the downloadable profile explains how.
Good Luck,
