The Sig 1/6 Cub is a hoot to fly you will love it.
By the way when I said "a lot"I did not mean how far, I was talking about how often you move it, as in that you would be making corrections often; perhaps I should have said it in that way, to avoid confusion. As you pick up speed, the time between your corrections will be spaced further apart, and the rudder will get real strong hence my statement about very slight movement needed.
As an aside, the cub is so responsive that you can make both the model and even a full size one, dance on the ground.

Jim was right on about the aileron setup to reduce adverse yaw, but you can learn how to cancel the adverse yaw by control inputs (the rudder). All high wings fall prey to adverse yaw and a lot of full scale aircraft use the method that Jim described regarding differential in the set up of the ailerons, "more up than down".
Have fun with it...
And good luck!
