Hello all,
I was designing a wing for my plane when I stumbled across this question. How to find the amount of polyhedral necessary in a plane? Is there any equation to find it out? How does the amount of polyhedral(length) needed vary with angle?
What is the amount of polyedral suggested for different types of planes?(cargo,trainer,aerial photography,glider etc.)

Thanks in advance!

interesting question.

may be this will help you https://www.rcgroups.com/forums/showthread.php?1804757-Dihedral-how-much

but it does not show how to calculate the angle.

Yes and wing sweep...how does that change the characterisitcs(quantitatively and qualitatively
)
Yes, that post was a bit useful.
