I'm using a "TOP GUN FOX 2 PRO" joystick which came in a package deal with the FS2004 package in March 2006 for about $90 total. It has plenty of features including throttle slide button and rudder yaw control by twisting the stick one way or the other (That feature would be nice on my trike in X-wind landings).
I've also downloaded and installed the Vista Oz packages (www.vistaoz.org/), which helps with the scenery, as well as a freeware FA-18 from I can't remember where, but it's a hoot to take for a blast through the Grand Canyon, 500kts at 50ft & bouncing off the walls occasionaly. No I don't fly that low in the real world. . .
Has anyone found any good trikes for FS2004?
Cheers,
Glen
