Thanks, aeajr.

In other words: a full yaw input (extreme left stick) will deflect the rudder 50% of the deflection achieved by a full roll input (extreme right stick).

You have made me change my approach to this issue, since I have been thinking surface instead of function until now.

I have a three channel glider with the roll function assigned to the left stick!..........Time to correct it.[sm=thumbs_up.gif]

Sure.

When you fly planes that have both ailerons and rudder and make use of the rudder, it is normal to go for the right hand to roll and the left hand to yaw.

On my AVA for example, there is only the rudder which produces both roll and yaw.

Rather than having to remember which plane, what surfaces it has and where they are located, I can actually access the rudder from either hand. So if I am looking to bank the plane to turn I naturally do that with my right hand, banking the plane, then pulling elevator as needed, same as I would with ailerons or elevons.

My Futaba 9C allows me to mix controls in this fashion. I have the left stick set up at 50% so that I get mostly yaw and less banking so I am less likely to over control the rudder when all I really want is the yaw effect. If I am looking to yaw the plane, such as on a landing, then I naturally go for the left hand.

So, both hands find what they want, even though I only have one surface doing the work.

I think function rather than surface. What do I want to do, not what surface do I want to use to do it.

BTW, on an elevon plane that has no rudder, like a flying wing, nothing gets mixed to the left hand as there is no yaw control on many elevon planes. There is only pitch and roll.
In a full-scale flying wing such as the B2 bomber they use what is called "split ailerons" that are computer controlled (like all other surfaces on the plane) to remove any yawing movement. A bit extreme for most models of course. And the space shuttle uses a split rudder for air braking.
