Fixed wing trainer set up with rudder only / no ailerons?

Previously I simply connected the aileron channel to my rudder servo. Is this still the only way to go or is there now a better way? I did search wiki didn’t seem to see anything yet I swear I saw something about this a year ago or so. thx

I haven’t tried it myself, but I’ve seen the section about rudder only planes before: http://ardupilot.org/plane/docs/parameters.html#rudder-only-rudder-only-aircraft

Don’t know if you’re using that.

ahhhh yes there it is thank you!
