Default "MIX 101" for newbies with mix capable radios

With just enough knowledge to be dangerous. (US Navy NFO flight training 32 years ago) Moving from a beginner 4 channel Tx to a 6 channel with mix capability. What are some common mixes for "normal" airplanes (not delta, or other unique ones). Additionally what situation would you want to "turn off" the mix? For example I understand that adding a little right rudder when aileron is pulled to the right helps "coordinate" the turn and pushes the tail around. It seems that perhaps during a aileron roll you would not want this. If I had this mix would I want to flip the switch and turn this mix off before executing aileron rolls? I have added a 50% rudder mix into my aileron for now and will experiment with rates set to low on next flight with my ultra micro T-28 which is the model which I am right now most comfortable with. Additional hints or tips for mixes which help smooth flight, and when I should consider turning them off? If there's an online reference for this kind of info, it would be awesome reading for me right now. Thanks in advance for any help in this area you may be able to provide.

I think the most common mix you will find is to add some elevator to flaps.

Rudder to aileron is too, but you are right.....you would want to disable it for
aileron or point rolls.

Helicopters don't really fly.......
They're just so ugly, that the earth repels them.

Without getting into mixes for 4 servo wing sailplanes (a book in itself), I have a few common mixes for my powered planes (fuel and electric).

Knife Edge mix - adds a little elevator to keep the plane from pulling to the canopy or gear (usually gear)

Elevator-Flaperon mix (switched) couples ailerons (acting as flaperons) to the elevator. One of my 3D planes (Edge 540 profile) has this set up on a 3 way switch. Off, Elev/Flaperons follow each other, Elevator/Flaperons work opposite of each other.

If you have a JR radio, then you can go to Horizon's site and read up on how they set up different radios with mixes and some very special things that they do. It's interesting to read anyway and you can learn how they do mixes.

The only mix that makes sense to me is to add down elevator to flaps for models that tend to balloon with flaps down. I use this mix just keep me from having to keep the stick down all the time that the flaps are deployed. My belief is that you should trim the plane to fly straight and level hands off and then use the sticks for all other controls. For me the idea is to fly the planes, not to have a computer do it for me.

Hmm, I can understand that point, flying it by hand.
But on the other hand (she wore a glove), Why not use the advancements/advantages available?

Seems to work for the airlines and military. Fly by wire.
Heck some real birds could not be flown by a pilot without computer aid.

Not saying you shouldn't understand the basic concepts and how to use them, but at least for me, any aid is a benefit, as long as it's not used as a crutch for not knowing how to fly a plane correctly.

Mixes/expo/differential and such can make a plane that's a bear to fly a joy.

Heck I'm still waiting on someone to come up with a voice warning system for me. "PULL UP-PULL UP"
"STALL-STALL" TREE- TREE" would be some good ones for me.

When I die, I want to go like my Grandfather did, in his sleep...... Not screaming like the passengers in his plane.
