Keith, I am not familiar with that TX so cannot tell you the particular steps but most TX will have either a separate mix just for this or you will have to go into your P mixes and assign the two channels you want mixed, the amount of mix and the directions.

That being said, I am curious as to why you desire such a mix as it is useful/required on only a very few models such as full house sailplanes or a Cub type airplane.

RC guys Decathlon 30cc gas. They say it flies better with a little rudder mix in with ailerons

Not being snarky but thats what your left thumb is for

But yes, a P-Mix with the master as the ailerons, the slave as the rudder and about 15 percent should do it.

Default Aileron to rudder mix

I had to get out my 9C to figure out how to do this again. I really don't like the programming on the 9C. But here goes...

Press and hold Mode/Page
Press Mode/Page to go to the Advanced Acro menu
You can turn the wheel (on the right) to highlight the Prog.Mix you want, but usually you can use Prog.Mix1
Press the wheel to select the Prog.Mix
Turn the wheel to set the rate for left and right. Move the aileron stick to select the right or left. I like to use +40% for both
Press Mode/Page
Turn the wheel to change MIX to OFF
Press Select (Cursor) (down) to select MAS
Turn the wheel to select AILE
Press Select(Cursor)(down) to select SLV
Turn the wheel to select RUDD
Press Select(Cursor)(down) until you get to SW
Turn the wheel to select the switch you want. I like to use H
Press Select(Cursor)(down) to select POSI
Turn the wheel to select DOWN
Press END twice to get out of the menus

This will set up switch H to turn on the AIL/RUD mix when it is flipped up (or towards you). You can play around with these settings to get exactly what you want.
Good luck!

Do they say anything about aileron differential? I would try that first.

A scale plane like that you're going to need some rudder to keep it from dragging its butt in a turn. I prefer to fly it rather than mix it because if you have a mix and you're landing its trying to turn while you are just wanting to level the wings with the ailerons.

Hi!
Agree fully! Never ever mix aileron with side rudder! Learn to fly using both of your hands/fingers instead!
Why! Because side rudder must be used separately in some situations and ailerons in some.

There is another good reason to mix rudder with aileron on a trainer with a steerable nose leg. It makes it much easier for the beginner to manage the transition from ground steering with the rudder to airborne steering with ailerons. Yes I totally agree that all beginners should work at educating the left thumb but lets make it easier to get off the ground.

Using aileron differential to reduce the adverse yaw will result in less rudder required for coordinated turns regardless of either using a mix or manual.

Best thing to do is learn how to coordinate your turns without the mix
