Constuction plan 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 construction plan print is delivered from the publisher (in contrast to the supplement construction plan) printed on one side and undivided on white paper. The delivery includes the building description.

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.
