I have a tyro 99 I am currently using a bulky fs-ia6b receiver and a fly sky fs-i6x transmitter. I am trying to hook up ibus. I bridged the middle pad and ibus pad together and soldered the yellow wire from receiver to ppm on under side of flight controller. I plug it in to beta flight and I get nothing on the receiver tab. I can move the sticks and nothing happens. I have my trans and receiver bound together my i6x is setup up to ibus
