Important! If you have not already built the wing check to see if it has the option of a smaller dihedral angle with ailerons or greater for use without ailerons. I would strongly suggest, if you have help, using the ailerons from the start. If you don't have help I would strongly suggest getting help and using ailerons. If you build it with a greater dihedral angle it will not perform as well later when you progress into more advanced maneuvers. With an instructor the smaller dihedral will still be sufficiently stable to learn easly.
