I've got to agree with Bruce, Grey Beard, and Somegeek as well. When I train a student I tell them to turn off ALL mixes in their radios (in fact, if possible I will have them us a radio that can't do mixes). Then when I teach them I show them how to use the sticks to coordinate their turns, or do other things by hand. This way they learn what is supposed do be happening before they try to set up a radio do it. Now I know that some may say that this is "bull" in this day and age of computer radios, that it's super simple to set up the computer to do mixes for you. Yes, this is a true statement. But I ask them this...... How is the student supposed to know what to setup? If they don't know how to manually perform what they are trying to program the radio to do, then how can they successfully program the radio to do it? Yes, they may be able to read on the internet how to do it. But IMHO it's better in the long run if the student has a working knowledge of what they are trying to do. I feel that it makes them a better all around pilot.

After a student has learned how to do it by hand I'm all for using the radio to take care of mixes such as Aileron-Rudder. In fact, I use it on m Slow Poke to help smooth out the flight.

That's my 2¢ worth
