There's a few really great ways. Let me post a pic of how i did a big powered glider for my friend. I set the ribs at the angle i wanted.

Chuck, are you staring at a pile of parts, or are you staring at two wing halves?

It's easy with a pair of flat-bottomed wing halves: just prop up the tips by the desired amount and join up the center section.  If they're symmetrical wings then you need to do other things.

So -- what do you have?

I have neither. I have been looking at a lot of plans and most call for a dihedral wing and I wondered how they are built. Thanks for your replies. y1

If you want to see how to do CL wings go to Stuka Stunt and do search on Al Rabes construction of his planes.   He is also here in the Vendors section if you would like to get all of his stuff on discs.    I have a set of his discs and they are well worth it.
