Re: dihedral
Hi romanxdsouza!!
Dihedral means the wing looks like a wide "V" when looked from the nose of the plane(), what you are saying (\___/ 5 20 5) is a Polyhedral.
2 inch Dihedral on 30 Inch Wing span means that the wing tips are lifted 2 inches up from the ground level while the wing root remains at the ground level. I don't know if it is a good definition of "what you need" but you can figure it out. You are always welcome to ask for more help.
Thanks.
Cheers.

Re: dihedral
So you need to modify the wing between the edges not the wing tips. Friend, The polyhedral or Dihedral are the terms actually applied to the whole Wing span not on the Leading or Trailing Edges of the wing. Do you mean to bend down the airfoil to achieve "Under Camber".

Re: dihedral
k let me try to explain friend im making a 30ws so want to know if 5 20 5 is ok for polydihedral, so wat im try to ask is if it is ok to make the same that is .........The tips could be short, about 5" long and would only need about 2" of dihedral or rise at the tips. so i then i would have a flat 20" center section and that is much easier to build and much stronger than having a dihedral joint in the center of the wing. im not making under cambered trying a simple kfm. im just trying to find out if this measures ar ok guess dihedral break is not the word
