Not to doubt what you're saying cwrr5, but that brace is a key item for the structural integrity of the wing, and the reason it's glued in before the bottom sheeting goes on is to insure that the brace is properly glued against all the other major components in that area. I can't see any way to insure that with the way the wing is constructed unless you have the sheeting off to double check all the glue joints. I think it would be a mistake not to take the sheeting off and glue the brace in properly, and for the little time it would take to do that, it would be worth it for the peace of mind knowing it was done right and you don't have to worry about the wing folding!

cwrr5 - I would only have a small gap where the dihedral brace inserts to apply the epoxy and I wouldn't be able to check any of the joints once it is in there, kind of like an arf.
Sorry guys, didn't mean to create any confusion. I'm modifying mine with a removeable blade type dihedral brace extending several rib bays more out into the wing inside a plywood/hardwood "box". Not to worry, it's plenty secure, and the technique has been used for a long time sucessfully. I just kind of went off on a tangent describing mine, and was not a suggestion for yours. sorry!
Here's another vote for counter-balancing the control surfaces. (just my opinion)
Looks good so far Gene... keep up the good work!
