I have a the Suncom dual throttle and win2k. Works fine - but I
have it hooked up to the Suncom F15 Talon joystick, and running both through a USB converter I got at Radio Shack.
Yep, Suncom is defunct. I don't expect any support. I paid about $50 for the both, and just expect it to last until the 2nd batch of Cougars ship.
I haven't noticed any advantage in flying the 38, but it sure is fun to advance the engines independently. When I tried to make my turn sharper by throttling back 1 engine, what I notice happening is the wing with power tends to rise. I suppose this is because of propwas flowing over the wing, causing a lift differential between the wing without power. I haven't noticed that I can crank a turn any sharper without spinning out. But I am by no means master of the 38. (or any other plane, for that matter).
I got mine at ebgames. Don't know where else they are available, but a search on Google should turn up something.
