No, it isn't smart to begin to learn to fly without using ailerons. None of the instructors at our club would start off a new student using rudder and elevator, only. Our instructors for the first flight or two, depending on the student, (simulator time if any, dexterity, etc.) limit the student to the right stick, elevator and ailerons. This gets the student used to the two control surfaces which contol, at least in part, altitude (pitch) and direction.

Find a good instructor at your local club. They will be glad to assist you.
