Yes, exsactly....that was the excuse I used for gettin' a computer radio...( heh heh heh ).

The Futaba 6Xas will do it...I know.....(some said it wouldn't)...
Flaps, flaperons, airbrake, and crow.....
As well as elevator to flap mix...
flaperon to elevator mix.....
And will reverse a servo...for like dual elevator servos....(use Ch. 5 as a slave off Ch. 2 ) This won't work, if you have retracts on Ch. 5.

The only thing the "6" won't do is... "couple - flaps/ailerons".
( the guy at Futaba told me...the "6" won't do this stuff, but they will ).

Bruckners in N.Y., sells 'em for $219., and If you ask him...he will include the 3004 BB servos...

How do you like the 120 size ??? I have a YS 120 4-popper lookin' for a home....
