IMHO the dihedral imparts a feeling of better tracking to the plane. A plane without dihedral will feel much more tippy, which is nice that it screams LIFT. The Paragon is a good example of the di and poly where Mirage is and example of the only poly, (my age is showing). > Does this advantage outweigh the weakening of the wing by introducing another join >in the most stressed part of the wing? It does if it helps you fly the plane more smoothly, but I think it mainly depends on YOUR flying style. On planes that are used it contest with landing task, it is a bonus to maneuvering close to the ground without catching a tip. Rich B RCSE-List facilities provided by Model Airplane News.
