I set up elevon mix on my dx6i and my new dx8, the problem is that the control surfaces move correctly with one radio but when i try to use other radio on same plane the control surfaces are all willy nilly.move the stick side to side and "elevator" moves. move stick back and forth, "ailerons" move. I want to fix this in the radio instead of switching servo wires around when i switch radios. reversing will not fix. any body have a fix. Thanx
