I did this on one of my models - but no longer have the hex for it!

It is not too complex.

Do you have 3 surfaces in total per wing?

So... elevator, aileron1, aileron2

Have you got aileron / elevator control working already?

Ok.... so you ate most of the way there!

Simply add in 4 mixes. One for each of the channels, setting the rudder stick as the input.

Adjust the weight to be -100 or 100 on each to get the direction right.

Actually this is not possible with only 2 servos per wing. If you do it with your current config of wing, you will get a hell of a lot of drag when deployed, with almost no rudder-effect, as the split of the counterworking sections are placed halfway in wing. It should be placed further out.

For better performance of the rudder, you need to split the aileron (which is placed in the right place for this) into 2 and add a servo for the added section. So then you have 3 servos pr. wing and can mix yourself a nice working drag-rudder B-2 style.

The mix goes like this:
Under both outer Ail channels/servos, you need one line with source iRud, weight 50%

Under both inner Ail-channels another line with source iRud, weight opposite above -50%

During full R-Rudder you should see this
