Also known as "flaperon" mixing, i.e. proportional down flap with up elevator and vice versa.

How much is enough?
How do you determine when you have too much?

Only objective is tight loops with no snaps, right?

With the mixer turned off, and playing with aileron droop, I notice down ailerons make the plane pitch down, up ailerons make the plane pitch up. Is this normal behavior?

I trim the airplane pitch by setting the elevator level with the stab, and setting aileron droop so trim is neutral in flight. This is something I do after I have the engine thrust line to my liking. Any problem with this strategy?

Note from the above, turning the mixer on will cause the flaps to cancel out some/most of the elevator pitch input. I have crashed a plane because of this, and not paying attention. Look Mom, no "up" :stupid:

I find myself cranking more and more elevator throw into my plane, only to increase the amount of flap defection with the mixer (Which of course seems to cancel out most of it)

How far is enough?
How tight should be loops get on a properly set up plane?
At what point do you conclude there is no (further) benefit?
What types of planes are better/less suited to this mix?

Is there a FAQ anywhere on setting up / trimming FF planes?
