I've got a Airtronics Legend (elev, rud, 2 ail and 2 flap). I'm needing a setup for a DX9 that gives me 4 flight modes,,,,,,I've got most of it worked out except for the flaps. I can't get them to attach to the throttle stick and the flap system doesn't show uo with a glider selected even with a 2 ail/2 flap wing type selected. HELP!
