I bought a Saitek ST290 Pro just for Freespace 2.
I also have a Logitech Wingman Extreme 3D Digital. Its twist sometimes needs to be rocked back and forth a couple times to settle it down when I start a game session. This is my second WE3DD stick. The first one absolutely would not calibrate the twist and I'd go corkscrewing along in any game that used the twist function unless I held it twisted off to the right. (Sorta like flying a P51-D Mustang, with extra turbocharging and nitrous oxide injection...)
I also have a Sidewinder Force Feedback Pro. Why MS made that beast gameport only, when they'd already introduced a USB version of the Sidewinder... The motors are so frigging big it looks like it could break your wrist.
For the Sidewinder 3D Pro die-hards,
http://en.wikipedia.org/wiki/Microsoft_SideWinder and
http://www.descentbb.net/viewtopic.php?t=7090 The person who built the USB converter isn't making more, but you can get the info to build your own. (Now if only someone would cook up same for the FF Pro!)
I think that forum thread also has some posts on how people have got the 3D Pro to work with XP by manually installing a standard 2-axis, 2 button stick, hooking up the Sidewinder, which gets detected as a 2-axis, 2 button stick- then deleting the first one they manually installed. Then XP smacks itself upside the head and recognizes the Sidewinder. You need the switch on the front of the base in the middle, between the | and ||.
I have an ADB version of the Sidewinder 3D Pro, but never could get it to work with Apple's Game Sprockets drivers or anything else on any Mac I tried it on. I have an ADB to USB adaptor that works with Mac mice and keyboards on Windows, I suppose drivers could be written for the ADB Sidewinder, or that it might possibly work on a Mac with the USB Overdrive drivers.
Most Force Feedback sticks have a sensor that prevents the stick from moving when there's no hand on it. CH uses a photocell on the right side of the handle while the Sidewinder has an IR emitter and sensor pair above and below the grip. Your fingers block the beam when your hand is on it. the CH one could be 'fooled' by a sufficiently dark room.
