Tough call on that one. Traditionally the rudder is operated from the aileron stick on a 3-channel plane but this has caused minor problems down the track when switching over to 4-channel planes and the "aileron" stick now won't keep the plane straight on takeoff or on a bungie/winch requiring the previously unused rudder stick to get some action. I can see the reason for having it "correct" from the start but it might be a mode I vs mode II human factor thing?

Now I'm experienced (?) I set up my 3 channel planes with the rudder on the correct stick BUT mix it over to the Aileron stick as well so I've got rudder on both sticks. Sometimes I find myself holding in a bit too much rudder and a bit of opposite "aileron" during a thermal turn like I do with the DLG ????
