Dunno' but I have these for my FSX Gold acceleration edition and am quite pleased with them.

I've seen others, tho I know nothing about them, ALL my stuff is Saitek, rudder peddles, flight yoke, throttle quadrant & joy stick,, the Aluminum & steel combat rudder pedals ran me bout 170.00 and the flight yoke & throttle quad bout 150.00 , the joy stick I picked off EBay new for 18.00 a year ago. Coupled with my Track IR5, which bout' 100.00 and I don't remember what Fraps cost me?  I have FSX Gold/ Acceleration edition, My puter has a XFX 6850 Graphics card with a Quad core processor and 12 GB of Ram.  I have 2 / 27" flat screens , and 1- 20" in. screen. that just on my Flight Sim Computer only,,,, my other computer across the Desk,, i'm on now has bout the same specs , minus the graphics card tho.   I am totally very pleased with all the Saitek componets I have, and have had no problems , its been over a year now. I mainly Fly Vintage propliners and Vintage older Jetliners from the 1950's 1960's 70's era , NOT really into all these over hyped Corporate logo Tubes thats out there now !!!
