Building the wing with dihedral
Here's a look at how the high dihedral wing is going together. Since flight without any added vertical stabilizer is desired, I've built in quite a bit of dihedral into this wing prototype.

Underside of wing; reflex / washout is set in the trailing edge first
The undercamber is done next; (I decided to use the creasing method on this wing.) The 4" tube and rolled counter top edge were used to do the shaping; GPW's "Bendfoam Jig" coulds be used if it will handle this long a wing panel
Center was sanded for dihedral joint, 'woodpeckered' so 5 minute epoxy would penetrate deeper, then glued. Lead weights& a handy block were used to hold everything in position while the epoxy set.
