Whats A Dihedral

[LandSpeed]

Hi
this is my first balsa build, I build plastic car models. anyway in the instructions on my 404 Zero it says not to cement the 1/4 inch leading edge to the dihedral joints at this time. this is before the install of the ribs. I hope this makes some sort of sense

Thanks

Dihedral is the amount the wings are angled toward one another, as opposed to being flat right across from side to side.
Imagine taking a flat sheet of paper, then folding it in 1/2. The unfold it.....you will then see the paper does not lay perfectly flat again, the two sides and angled a bit. That angle is dihedral.

The joint mentioned is the section where you are joining the 2 wing halves together during the build. Its telling you not to glue the wing halves together yet, just build the 2 wing panels flat first because later you will be lifting one wing up at an angle to the other and then gluing the 2 panels together. Thereby you put a certain amount of dihedral in.

Make sense the way I explained it?

Thanks for the help. It makes sense now.
The fuselage went together well. I'll get the wing finished, then the big job of the papering. I will have lots more questions coming up and maybe some pictures.
