hi chimp. I just tried putting my old analog CH throttle on my USB converter, and it kind of works. You can see the throttle axis going up and down etc no probs, but none of the buttons work. I suspect you would have to plug the extra keyboard bypass plugs between your keyboard and then either install the CH software, or just map the keys to functions within AH. I dont think the first option would work as CH say you cant mix USB and analog gear. So try the second. Converters are cheap you can get em of the web or at your local radioshack or equivalent. I selected the mode switch on my RockFire converter to mode 2 which is 4 axis, 4 button joystick - the 4th axis being the throttle axis. Seemed to work. You would then just need to 'inline' the keyboard and map which ever keys they simulate to whatever you want them to be in AH and remap any default conflicts as required.
