If your having problems getting your flight controls whatever they might be to get recognized by EAW v1.2 try these programs. I only got one report that said these programs work well with combining controllers, throttles, pedals of different brands into one virtual joystick. EAW v1.28c and up supposedly support 3 devices and separate pedals and throttles natively, but people are still having problems. So these programs may help even with those versions of EAW, including 1.40.
I haven't added this info to my EAW Joystick help guide yet as I haven't been able to test them out myself as I only have one controller. http://eaw.neocities.org/eaw-joystick-remappable.html
Try these two programs that I'll link. They combine multiple controllers into 1 virtual joystick.
