This paper is a based on work by Werner Würz, published in the papers of the ISF-Seminar¹ in December 1989 in Baden, Switzerland. Dr. Würz built and performed drag measurements on linkages, as they are used on the wings of F3B models. These models are usually equipped with flaps and ailerons, which are driven by 2 micro-servos in each wing, resulting in a total of four control horns and pushrods. Although these parts have only a small frontal area, they cause additional drag, which had not yet been examined on model aircraft. |
