Rudder servo control on (left)throttle stick -vs- rudder control on (right)stick.
 
My son is experienced Slow Stick flyer with rudder control on right control stick. We now have purchased 3D plane with ailerons. Does anyone have any expert advice regarding keeping the rudder control on the right stick and moving the aileron control to the left stick?

You're better off connecting the ailerons to the right stick.
After all, he learned to turn in the air, using the right stick.
The ailerons will turn better than the rudder.
The rudder then goes on the left stick.
And he'll be able to fly other people's airplanes which are set up this way.

Typically, the primary yaw control is put on the right stick. On a rudder-elevator plane, the primary yaw control is the rudder. But on a rudder-elevator-aileron plane, primary yaw control becomes the ailerons and the rudder is used for different purposes.

Move the rudder to the left stick. The learning curve is quite minimal.

Thanx. We did move the rudder control on his Slow Stick to the throttle stick and he crashed right away because it was so foreign to him. Note: he is very experienced with turning the plane with the right stick; however, it was my suggestion that we move rudder control on Slow Stick so he gets familiar with rudder on throttle stick. Do you have any suggestions on how he can make the migration to left stick rudder? Perhaps i don't realized that the ailerons will now provide the majority of the turning?

Can you explain "Yaw" ? (new term for us)

The way I meant yaw is synonymous with bank or lean.

I wouldn't move the rudder to the left stick on a plane without ailerons. Leave it on the right stick. You typically only put the rudder on the left stick on a plane with ailerons because they replace the rudder as your primary bank or yaw control.

Thank You! This forum has made all the difference with my son learning to fly rc planes.

The three motions of a plane are:
Pitch... around an axis extending out the wing.. Vertical rotation around that axis is usually controlled by the elevator.
Roll... rotational motion around a line going from nose to tail, generally along the center of the fuselage. Usually controlled by the ailerons.
Yaw... rotational motion around a vertical axis extending up and down thru the airplane's center of mass. Usually controlled by the rudder.
The rudder when used as the turning control relies on the wing's dihedral to achieve the change in the roll axis which moves the nose around in a turn due to the imbalance of forces on the dihedralled wing.
With no dihedral, rudders tend to be ineffective.
Ailerons turn the plane by creating an unbalance of forces around the longitudinal axis.. more on one side, less on the other.. the airplane turns toward the side with the lesser force.
Due to the force setups in the other axes, the plane turns as well as rolls.
Ailerons tend to be the primary flight control for most models..
Rudders tend to ineffective with most planes at speed, so these are considered secondary flight controls.

Ok, when I said yaw I meant roll but bank will work too. Of course a rudder-elevator plane typically has exaggerated dihedral which causes the plane to roll or bank when the rudder yaws it so ....

Aw, never mind! ;)

Well - say what you mean and mean what you say.. ;)

Yaw and roll are completely different..

You can "yaw" the airplane and keep the wings level.. You cannot roll the airplane and keep the wings level..

ive flown a 3 channel and then convert to 4 channel.

It was only natural to have the primary turning control on the right. The rudder becomes a secondary part of flying that you re-learn to use in an aileron plane for onlly balancing the turns (initially)

Hey Tram I think you CAN roll a plane and keep the wings level - if you're landing on a rolling carrier deck! Depends on your point of reference. :D

Speaking of which - rudder on the right when it's all you've got, move it over to the left when you have ailerons. Keeps the thumbs happy and lets everybody else fly your model, which is what we all want... right? ;)

You'll want the "primary turn control" on the right stick, no matter what you call it.

So on a R/E only model, rudder on the right. On a model with ailerons, however, put them on the right, rudder on the left. On an aileron ship, you won't use a rudder to turn as you did on the R/E one..

If you land on a rolling carrier deck - your wings are level with the ship's deck but not the horizon.. :) The attitude indicator would still indicate a roll.. :D

you said that exactly right, except for one phrase.

Substitute "turn control" for the three uses of the words "yaw control".

As other have mentioned, roll and yaw are not the same thing...:)
