I am setting up my first plane (I am currently into helis). I have a friend that is going to help me tweak the plane at the field but I need help now. I bought an uproar and need help with radio setup with the dx7. I know the following for servo to rx. thro to thro rud to rud ele to ele. What I can't figure out is what to do with the alirons. Do I turn Flapperon on in the radio. Help.
