Default No, its a poor idea

The point of coupling rudder to the aileron either by computer radio or with a 'y' cord is to minimize an effect called adverse yaw which causes a tendency particularly in climb for the nose of the airplane to point in the opposite direction of a turn. That thread is in the context of the training environment. This adverse yaw is most prevelant with high wing cabin types (trainers) and minimal with a low wing. therefore coupling is not useful and can cause some other problems with a low wing.

Rudder and elevator on the same channel won't accomplish anything but making a modern model uncontrollable. You'd be coupling your pitch and yaw controls. I can't think of why anyone would suggest that, other than for malicious reasons.

Default OK!

Well. Strobelight, the question is so bizarre that the first two replies talk about aileron/rudder not elevator/rudder. I guess those gentlemen misunderstood as well.

As MikeL says, it serves no purpose to mix elevator and rudder. What would you be hoping to accomplish?

Did you by chance mean the same STICK rather than the same CHANNEL?

Default No confusion here

It seemed obvious that ail to rud mix was what he was talking about particularly since he seemed to be referring to a commercial flight school of which there are only a few and at least one does use this method for primary. My intent was mearly to expand the reasons for the practice.

If someone replied with just a question that may possibly be construed as rude as in #6, then I may become a bit defensive also with the resultant breakdown in communications.

Well John maybe you could explain what is rude about #6. I merely asked if the gentlemen was really asking the right question, and he repeated that he was.

So much for being obvious.

Default 3 channel?

On a 3 channel plane you've only got rudder and elevator. I find that you need to feed in a little up when you turn with the rudder.
This is on a polyhedral plane which banks quite readily in response to the rudder.

But then coupling the two together might screw things up if you needed to use the elevator on its own....
