I have a twin tail Stryker and I want to program the rudders to act as speedbrakes. I.e., when I flip a switch the rudders either both go in or both go out depending on how I have them setup. Right now I have right rudder on ch4 and left rudder on ch6, then have a rudder to flap mix to operate them together. My radio is a 9C on 2.4. Can anyone help me out with the proper programming to do this? thanks, Steve.
