Wooden parts set Mullisch 3.1

The Mullisch 3.1 is a flying wing for methanol engines developed by Tim Weißbach, which complies with the Club Pylon rules: In this competition class, there are a rectangular wing with a span of at least 900 mm and an area of at least 18 dm² as well as a box fuselage with certain minimum dimensions and a minimum weight of 1,100 g (dry) specified. The enclosed construction plan was published in FMT 07/2023.

The wooden kit contains all components such as ribs and frames made of balsa and plywood in selected quality and control horns made of GRP. In addition, strips, CFRP profiles, linkage accessories and the wing screw connection are included in the kit. RC components, a tank and adhesives, foil and paint are also required.

The stated goal of the Club Pylon racing class should be to fly races with commercially available, inexpensive equipment and low construction costs. It must be possible for every conventionally equipped model builder to create a competitive model without special equipment. Furthermore, expensive special engines, high-tech aircraft, subjective evaluations by judges or complex scale documentation should not decide victory or defeat, but exclusively the technical and flying skills and the nerves of the pilot teams.

In addition, the fun factor should not be neglected.
