weather vane effect on sailplanes
if a plane has too much side area behind the cg it may have the tendency to point at the wind and resist going any other way.
just like a weather vane. resisting to change direction.
Frank Zaic mentioned a method to keep this in balance by a very simple method without calculations. he called it center of lateral area.
from cardboard he cut a profile of the model showing all the components viewed from the side, including the side of the wing with the dihedral. then pinned it at the desired cg and saw if it balanced. i tried it with all my models and it worked.
if any1 has some experience with this, please bring it.
please only comments polite, positive and to the point.
i started a thread on the issue here:
