I used a 10C when I wrote [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=1134]THIS REVIEW[/link]. Then I gave the plane to my dad and he's been flying it with a 6EX ever since
A six channel will work but both ailerons and flaps will need to work off of a Y cable. I like to have the ailerons on separate channels so that differential can be set if needed. That is why I would use a Futaba 7C radio.
